A large number of electronic consumer products, automotive electronics, aerospace equipment, military equipment, etc. have added satellite navigation modules. Comprehensive, scientific and accurate quality assessment of navigation products has become a widespread and urgent need. Generally, automated test systems are used to perform automated testing on navigation products. Automated test systems use instructions to automatically manage and control the equipment under test and various instruments. Its application has penetrated into all aspects of product development from prototype to production.

[0003] However, the test contents and projects of satellite navigation equipment are increasing, the test cycle is getting longer, and the test requirements are constantly changing, which makes the design of the automated test system complex and unable to respond quickly to changes in requirements.

[0011] Furthermore, step S1 further includes the steps of:

[0012] The workstation setting principles are checked to prevent abnormal workstation settings and signal connections, provide correct workstation information for subsequent parallelization, and perform signal calibration on the equipment based on the signal connection between the equipment in the test environment and between the equipment; the equipment workstation setting principles are as follows: shared equipment can be connected to all workstations, and workstation equipment is only connected to the equipment in this workstation and shared equipment. Equipment at one workstation is prohibited from being connected to equipment at another workstation. The equipment type, quantity, and connection method in each workstation should be consistent. Equipment placed in a certain workstation is called workstation equipment, and equipment that does not belong to any workstation is called shared equipment.

[0013] Further, in step S2, the test item consists of a test sequence and a variable set, the test sequence consists of an ordered connection of different test steps and parameter configurations of the test steps, the test steps include a general process control step, a processing instruction step, and a device instruction step, the general process control step includes a condition judgment step, a loop step, a parallel step, a test start step, a test end step, and an expression step; the test step includes a required entry port, an exit port, and an optional branch port, wherein the selection mode of the branch port is divided into a mutually exclusive selection mode, a parallel selection mode, and a loop selection mode, the mutually exclusive selection mode means that only one of the branch ports is selected to run according to the condition, the parallel selection mode means that all branch ports are run in parallel, the loop selection mode means that the branch port is repeatedly run until the condition is not met, and the loop selection mode can only contain one branch port; the exit port or branch port of the test step is connected to the entry port of another test step in a directed manner, but the exit port is prohibited from being connected to its predecessor, that is, the test sequence is a directed non- Ring graph, the nodes of the graph are test steps, and the directed edges of the graph are directed connections between ports; the test start step represents the entry point of the test sequence process, and the entry port of this step is prohibited from being connected; the test end step represents the end of the test sequence process, and the exit port of this step is prohibited from being connected; the variable set includes multiple variables, each variable includes a variable name, data type, initial value, parameter tag, and workstation tag. The variable data type can only be selected from the preset data type component. A data type component provides support for a data type used in the test, including the name of the data type and a class definition code of the data type, including basic data types: integers, floating point numbers, strings, dates, and data containers, etc. Provide built-in support; parameter tags are divided into parameter variables and running variables. Parameter variables set values ​​before testing, and can only take values ​​during the test, but cannot change values. Running variables do not have the above restrictions. Workstation tags are divided into workstation variables and shared variables. Workstation variables have an instance at each workstation, and shared variables have only one instance;

[0014] When setting the test step parameters, it includes setting the conditional expressions of conditional steps and loop steps, setting the parameter expressions of processing instruction steps and device instruction steps, and the variables for saving the return values ​​of instruction calls;

[0015] When setting the visualization configuration of the test process, the display mode of the test data generated by the test process and saved in the variables is set by binding the variables to the display components of text, curves and charts.

[0016] Furthermore, step S2 further includes the steps of:

[0017] Provides a test item checking mechanism. When configuring a test item, it checks in real time whether the test steps are valid and gives prompts for invalid places, including expression checking, checking whether all expressions conform to the expression specifications and whether the input parameter data type matches the data type of its expression.

[0018] Further, in step S3, the test item test mode includes a serial test mode, a parallel test mode, and a mixed test mode. The serial test mode tests one workstation at a time until all workstation tests are completed; the parallel test mode only tests once, and all workstations are tested simultaneously; the mixed test mode is a multi-pass test, each time testing one or more specified workstations until all workstation tests are completed.

[0019] Furthermore, in step S4, the test items are loaded, the station set for the current test is determined, and the variable set is initialized, which specifically includes the following steps:

[0020] According to the set test mode of the test item, determine the station set of the test item in this test pass, the station set includes the station ID of the station tested in this test pass;

[0021] Instantiate the workstation variables and set the initial values. Instantiate the workstation variables according to the workstation set, and index the workstation variables and workstation equipment through the workstation ID.

[0022] Further, in step S4, the test sequence directed acyclic graph is analyzed to determine the synchronization point mark of the test step entry port and the execution mode of the test step, which specifically includes the following steps:

[0023] Traverse the directed acyclic graph formed by the test sequence to determine the execution mode of each test step, wherein the test step using the station equipment or station variable is the station step, and the other test steps are shared steps, all shared steps are in the merged execution mode, the station step using the modified processing instruction or shared running variable is in the serial station execution mode, and the station step with a branch port, if the step of the subgraph where its child node is located contains a test step of the merged execution mode or the serial station execution mode, then this step is in the serial station execution mode, and the remaining station steps are in the parallel station execution mode;

[0024] When determining the synchronization point mark of the test step entry port, the entry endpoint of each test step whose execution mode is the merge execution mode or the serial station execution mode is marked as a synchronization point.

[0025] Further, in step S4, an initialization control group and control flow are created, and all control flows are placed in the entry port of the test start step, specifically including the steps:

[0026] Initially, an initial control group is created, including a group ID and a workstation ID set. The workstation ID set contains the workstations that need to be tested. A control flow is created for each workstation. The control group to which the control flow belongs is the initial control group. All control flows are placed at the entry port of the test start step at the same time.

[0027] Further, in step S4, according to the control flow operation rules, the control flow is made to stay and flow on the test sequence directed acyclic graph, the operation of the test steps is controlled, and the automatic control of the serial and parallel timing of multiple stations is completed, which specifically includes the steps of:

[0028] When the control flows into the entry port of a test step, if the port is not marked as a synchronization point, the control flow flows directly into this test step. If the entry port is marked as a synchronization point, the control flow stays at the entry port and needs to wait until all control flows in the control group to which it belongs also arrive at this entry port before all control flows in the control group can flow into this test step at the same time;

[0029] After the control flows into the test step, it stays in the test step and is processed according to the following rules:

[0030] When the test step is in the merge execution mode, the control flows that stay in the test step are grouped according to the control group, and the following processing is performed on each control group: the operation represented by this test step is executed, and the operation result is temporarily saved. If there is no branch port, this test step is executed, and all control flows in the control group flow into the next subsequent port at the same time. If there is a branch port, a copy is made of the control group and the control flow in the group as a sub-control group of the current control group. The copied control flow is the sub-control flow. All control flows in the current control group are set to a suspended state. According to the step operation result and the selection mode of the branch port, all sub-control flows flow into the branch port and run until all sub-control flows have finished running. All control flows in the current control group are restored from the suspended state, and all control flows in the control group flow to the next subsequent port;

[0031] When the test step is in serial workstation execution mode, the control flows that stay in the test step are grouped according to control groups, and the following processing is performed on each control group: the following processing is performed serially on each control flow in the control group: the operation represented by the control flow in the test step is executed, and the workstation equipment and workstation variables referenced by the test step are different according to the workstation ID of the control flow; if there is no branch port, the control flow is processed; if there is a branch port, a copy of the control flow is made, and the copied control flow is a sub-control flow, and the control group of the sub-control flow is a new control group. The workstation set of the new control group only contains the workstation of the current control flow, and the current control flow is set to a suspended state. According to the test step operation result and the selection mode of the branch port, all sub-control flows flow into the branch port and run until the sub-control flow is completed, the current control flow is restored from the suspended state, and the control flow is processed; after all control flows in the control group are processed, all control flows in the control group flow to the next subsequent port;

[0032] When the test step is in parallel workstation execution mode, the following processing is performed in parallel for each control flow that stays in the test step: the operation represented by the control flow in the test step is executed, and the workstation equipment and workstation variables referenced by the test step are different according to the workstation ID of the control flow; if there is no branch port, the current control flow flows to the next subsequent port; if there is a branch port, a copy of the control flow is made, and the copied control flow is the sub-control flow, and the sub-control group of the sub-control flow is a new control group. The workstation set of the new control group only contains the workstation of the current control flow, and the current control flow is set to a suspended state. According to the step operation result and the selection mode of the branch port, all sub-control flows flow into the branch port and run until the sub-control flow is completed, the current control flow is restored from the suspended state, and the current control flow flows to the next subsequent port.

[0033] Furthermore, according to the step operation result and the selection mode of the branch port, all sub-control flows flow into the branch port and run, specifically including the steps of:

[0034] For the mutually exclusive selection mode, the sub-control flow selects to enter a branch port according to the condition of step operation; for the parallel selection mode, the sub-control flow enters all branch ports in parallel; for the loop selection mode, the sub-control flow selects one branch port to enter;

[0035] The control flow to the next subsequent port specifically includes the following steps:

[0036] If the selection mode of the branch port of the test step is the loop selection mode, the calculation result of the conditional expression is judged. If it is true, the next subsequent port is the entry port of the test step. In all other cases, the next subsequent port is the exit port of the test step.

[0037] The sub-control flow has completed execution, including the following steps:

[0038] When a sub-control flow enters a branch port or an exit port, and the branch port or the exit port is not connected to any port, or the sub-control flow enters the test end step, the sub-control flow is completed. Otherwise, the sub-control flow follows the directed connection and reaches the entry port of the subsequent test step to continue running until it is completed.

[0042] The third setting module is used to set the test plan, connect the test equipment, set the test item test mode, and then read the test environment file and the test item file to start the test;

[0043] The test and display module is used to run the test items in the test plan in sequence according to the test plan. For each test of the test item, the following processing is repeated until the test is completed: load the test item, determine the station set for this test, and initialize the variable set; analyze the directed acyclic graph composed of the test sequence, determine the synchronization point mark of the test step entry port, and determine the execution mode of the test step; create an initialization control group and control flow, and put all control flows into the entry port of the test start step; according to the control flow operation rules, make the control flow stay and flow on the directed acyclic graph of the test sequence, control the operation of the test steps, and complete the automatic control of the serial and parallel timing of multiple stations; display the test data and test results in real time according to the visual configuration of the test item.

[0061] The embodiments of the present application are described in detail below in conjunction with the accompanying drawings, but the present application can be implemented in a variety of different ways defined and covered below.

[0062] like Figure 1 As shown, the preferred embodiment of the present application provides an automated parallel testing method for a satellite navigation device, comprising the following steps:

[0063] S1. After setting the device under test, the signal connection method of the instrument, and the workstation of the device, save the relevant data into the test environment file;

[0064] S2. After setting the test step flow, test step parameters, variable set, and visual configuration of the test process of the test item, save the relevant data into the test item file;

[0065] S3, after setting the test plan, connecting the test equipment, setting the test item test mode, reading the test environment file and the test item file to start the test;

[0066] S4. According to the test plan, run the test items in the test plan in sequence. For each test of the test items, repeat the following processing until the test is completed: load the test items, determine the set of workstations for this test, and initialize the variable set; analyze the directed acyclic graph composed of the test sequence, determine the synchronization point mark of the test step entry port, and determine the execution mode of the test step; create an initialization control group and control flow, and put all control flows into the entry port of the test start step; according to the control flow operation rules, make the control flow stay and flow on the directed acyclic graph of the test sequence, control the operation of the test steps, and complete the automatic control of the serial and parallel timing of multiple workstations; display the test data and test results in real time according to the visual configuration of the test items.

[0067] Figure 2It is an automated parallel testing system for implementing the above method, which consists of a general automated testing platform, an external component set, a test environment set, and a test item set. The automated testing platform and the external component set mainly exist in the form of software code, and the test environment set and the test item set are data accessed by the software and exist in the form of files, including test environment files and test item files, respectively.

[0068] Various components define component interface definitions with unified interface specifications. Developers and users can add components to the automated testing platform as needed. The platform provides a framework for managing and running components, as well as a test environment editor and a test editor to provide editing, debugging, and running functions for the test environment and test items respectively.

[0069] Necessary external component types include: data components, test step components, equipment components, and processing instruction components. Each component type contains many components of the same type. Users can generate components through code. The following describes each type of component:

[0070] A data component in the data component collection provides support for a data type used in the test system, including the name of the data type and a class definition code for the data type. The platform provides built-in support for basic data types such as integers, floating-point numbers, strings, dates, and data containers.

[0071] Each test step component in the test step component set is an executable unit that can be placed in the test flow, and is used to orchestrate the test process in the test sequence, including the test step definition and its implementation code. The test step definition includes: step unique identifier, step name, number of branch ports and parameter definition. According to the selection mode of the branch port, it is divided into mutually exclusive selection mode, parallel selection mode and loop selection mode; the mutually exclusive selection mode means that only one of the branch ports is selected to run according to the condition, the parallel selection mode means that all branch ports are run in parallel, and the loop selection mode means that the branch port is repeatedly run until the condition is not met. The loop selection mode can only contain one branch port.

[0072] The platform provides basic test step components, such as general process control types: conditional judgment steps, loop steps, parallel steps, test start steps, test end steps, expression steps, as well as processing instruction steps and device instruction steps. Figure 3As shown, all test steps have an entry port and an exit port, and the branch port only exists in the test steps of the process control type. For example, the condition judgment step has two branch ports, representing the running branches when the condition is true and the condition is false respectively. The loop step has one branch port, representing the branch of the loop running when the loop condition is met; the parameter definition refers to the input parameters of the test step. For example, the parameter of the condition judgment and loop steps is a Boolean expression, and the parameter of the parallel step is an integer, which represents the number of parallel branches.

[0073] The device components in the device component collection are devices, instruments, or other hardware and software entities that can be controlled by instructions used in the test system, including device definitions and their implementation codes. The device definition includes the device unique identifier, device name, device connection method, number of signal ports, the name of each signal port, the type of signal flowing on the signal port, and the signal transmission direction.

[0074] The device component also contains the definition of its device instruction set, which contains multiple device instructions. The device instruction is the smallest operating unit for operating the device. The definition of the device instruction includes the name of the device instruction, a detailed description of the instruction, the name and data type of the instruction input parameter, the data type of the instruction return value, and the instruction type. The data type can only be selected in the data type component. The instruction type is divided into change-type instructions and non-change-type instructions. Change-type instructions mean that the instruction will change the device status, and non-change-type instructions mean that the instruction will not change the device status. The device instruction can be called in the device instruction step. The parameters of the device instruction step are composed of the device unique identifier of the called device instruction, the name of the device instruction, the input parameter expression, and the return value.

[0075] The processing instruction components in the processing instruction component set include processing instruction definitions and their implementation codes. The processing instruction components mainly include some data processing instructions such as calculation, analysis, and evaluation. The definition of the processing instruction includes the processing instruction name, a detailed description of the instruction, the input parameter name and data type of the instruction, the data type of the instruction return value, and the instruction type. The data type can only be selected in the data type component. The processing instruction can be called in the processing instruction step. The parameters of the processing instruction step are composed of the processing instruction name, input parameter expression, and return value of the called processing instruction.

[0076] The automated testing system provides a test environment editor that can load, edit, and save the test environment. In the editor, the required devices in the device components can be added to the environment. The matching signal ports of different devices can be connected using lines. One or more workstations are created in the environment. The device or devices under test can be placed in the workstation. The device placed in a certain workstation is called a workstation device, and the device that does not belong to any workstation is called a shared device. The principle of device station setting is as follows: shared devices can be connected to all workstations, and workstation devices are only connected to devices in this workstation and shared devices. Devices in one workstation are prohibited from being connected to devices in another workstation. The type, quantity, and connection method of the equipment in each workstation should be consistent.

[0077] The test environment editor detects the station setting principles to prevent abnormal station settings and signal connections, provides correct station information for subsequent parallelization, and performs signal calibration on devices based on the signal connections between devices in the test environment.

[0078] The automated test system provides a test item editor, which can load, edit, save, debug and run the test items. The test items are composed of test sequences and variable sets. The test sequence is composed of the ordered connection of different test steps and the parameter configuration of the test steps. The exit port or branch port of the test step can be connected to the entry port of another test step in a directed manner, but the port is prohibited from connecting to its predecessor, that is, the test sequence is a directed acyclic graph, the nodes of the graph are test steps, and the directed edges of the graph are directed connections between ports. The test start step represents the entry point of the test sequence process, and its entry port is prohibited from being connected. The test end step represents the end of the test sequence process, and its exit port is prohibited from being connected. The variable set includes multiple variables, each variable consists of a variable name, data type, initial value, parameter tag, and station tag. The variable data type can only be selected in the data type component. The parameter tag is divided into parameter variables and running variables. The parameter variable can set the value before the test, and can only take the value during the test, but cannot change the value. The running variable has no such restriction. The station tag is divided into station variables and shared variables. The station variable has an instance at each station, and the shared variable has only one instance.

[0079] The test item editor also sets parameters for the test steps in the test sequence, such as setting conditional expressions for conditional steps and loop steps, setting parameter expressions for processing instruction steps and device instruction steps, and setting variables for saving the return values ​​of instruction calls.

[0080] The automated testing system provides a test item checking mechanism. When configuring the test items, it checks in real time whether the test steps are valid and gives prompts for invalid places. For example, expression checking checks whether all expressions comply with expression specifications, whether the input parameter data type matches the data type of its expression, etc.

[0081] The automated testing system provides visual configuration of the testing process and completes the setting of the display mode of the test data generated by the testing process and saved in the variables, for example, by binding the variables to various display components such as text, curves, and charts.

[0082] The automated testing system provides a test running engine. When testing needs to be implemented, the user loads the required test environment and adds the test items to be tested to the test plan. The system automatically checks the validity of the test items and the matching of the test items with the test environment, and issues prompts for problematic areas. The system obtains the environment and workstation information and determines how many workstations in the test environment are used for testing.

[0083] The user connects the device in the test environment to the real hardware device and modifies the test item parameters as needed. The user determines the test mode of the test item, which is divided into serial test mode, parallel test mode, and mixed test mode. The serial test mode tests one station at a time until all stations are tested. The parallel test mode only tests once, and all stations are tested at the same time. The mixed test mode is a multi-pass test, each time testing one or more specified stations until all stations are tested.

[0084] Compared with the prior art, this embodiment has the following beneficial effects:

[0085] 1. The automated parallel testing method for satellite navigation equipment of this embodiment provides an automatic parallelization mechanism, automatically derives serial test sequences, solves resource conflict problems, and thus generates parallel control timing in real time, maximizes the parallel rate and resource utilization efficiency of the system, and reduces the difficulty of writing and debugging parallel test programs;

This embodiment provides highly flexible and highly customized support through an extensible architecture design: it provides a device expansion mechanism, can continuously expand multiple types of devices and instruments, encapsulates device instruction sets, provides an expansion mechanism for processing instructions, and improves test processing functions.

[0089] 5. This embodiment can be used as a general automated parallel test, which can not only respond quickly to changes in demand and has great flexibility and scalability, but also automatically optimize test time and space efficiency to reduce test costs. While meeting the needs of the satellite navigation test field, it also supports other fields that require automated control and testing, greatly reducing the R&D cost of the test system.

[0090] Preferably, in a preferred embodiment of the present application, step S1 further comprises the steps of:

[0114] When the control flows into the entry port of a test step, if the port is not marked as a synchronization point, the control flow flows directly into this test step. If the entry port is marked as a synchronization point, the control flow stays at the entry port and needs to wait until all control flows in the control group to which it belongs also arrive at this entry port before all control flows in the control group can flow into this test step at the same time;

[0115] After the control flows into the test step, it stays in the test step and is processed according to the following rules:

[0116] When the test step is in the merge execution mode, the control flows that stay in the test step are grouped according to the control group, and the following processing is performed on each control group: the operation represented by this test step is executed, and the operation result is temporarily saved. If there is no branch port, this test step is executed, and all control flows in the control group flow into the next subsequent port at the same time. If there is a branch port, a copy is made of the control group and the control flow in the group as a sub-control group of the current control group. The copied control flow is the sub-control flow. All control flows in the current control group are set to a suspended state.

[0117] When the test step is in serial workstation execution mode, the control flows that stay in the test step are grouped according to control groups, and the following processing is performed on each control group: the following processing is performed serially on each control flow in the control group: the operation represented by the control flow in the test step is executed, and the workstation equipment and workstation variables referenced by the test step are different according to the workstation ID of the control flow; if there is no branch port, the control flow is processed; if there is a branch port, a copy of the control flow is made, and the copied control flow is a sub-control flow, and the control group of the sub-control flow is a new control group. The workstation set of the new control group only contains the workstation of the current control flow, and the current control flow is set to a suspended state. According to the test step operation result and the selection mode of the branch port, all sub-control flows flow into the branch port and run until the sub-control flow is completed, the current control flow is restored from the suspended state, and the control flow is processed; after all control flows in the control group are processed, all control flows in the control group flow to the next subsequent port;

[0118] When the test step is in parallel workstation execution mode, the following processing is performed in parallel for each control flow that stays in the test step: the operation represented by the control flow in the test step is executed, and the workstation equipment and workstation variables referenced by the test step are different according to the workstation ID of the control flow; if there is no branch port, the current control flow flows to the next subsequent port; if there is a branch port, a copy of the control flow is made, and the copied control flow is the sub-control flow, and the sub-control group of the sub-control flow is a new control group. The workstation set of the new control group only contains the workstation of the current control flow, and the current control flow is set to a suspended state. According to the step operation result and the selection mode of the branch port, all sub-control flows flow into the branch port and run until the sub-control flow is completed, the current control flow is restored from the suspended state, and the current control flow flows to the next subsequent port.

[0119] Preferably, in a preferred embodiment of the present application, the step of flowing all sub-control flows into the branch port and running them according to the step operation result and the selection mode of the branch port specifically includes the steps of:

[0120] For the mutually exclusive selection mode, the sub-control flow chooses to enter a branch port according to the condition of the step operation; for the parallel selection mode, the sub-control flow enters all branch ports in parallel; for the loop selection mode, the sub-control flow selects a branch port to enter.

[0121] Preferably, in a preferred embodiment of the present application, controlling the flow to flow to the next subsequent port specifically comprises the steps of:

[0122] If the selection mode of the branch port of the test step is the loop selection mode, the calculation result of the conditional expression is judged. If it is true, the next subsequent port is the entry port of the test step. In all other cases, the next subsequent port is the exit port of the test step.

[0123] Preferably, in a preferred embodiment of the present application, the sub-control flow is completed, specifically including the steps of:

[0124] When a sub-control flow enters a branch port or an exit port, and the branch port or the exit port is not connected to any port, or the sub-control flow enters the test end step, the sub-control flow is completed. Otherwise, the sub-control flow follows the directed connection and reaches the entry port of the subsequent test step to continue running until it is completed.

The method for automated parallel testing of satellite navigation equipment according to claim 9, characterized in that: According to the step operation result and the selection mode of the branch port, all sub-control flows flow into the branch port and run, specifically including the steps of: For the mutually exclusive selection mode, the sub-control flow selects to enter a branch port according to the condition of step operation; for the parallel selection mode, the sub-control flow enters all branch ports in parallel; for the loop selection mode, the sub-control flow selects one branch port to enter; The control flow to the next subsequent port specifically includes the following steps: If the selection mode of the branch port of the test step is the loop selection mode, the calculation result of the conditional expression is judged. If it is true, the next subsequent port is the entry port of the test step. In all other cases, the next subsequent port is the exit port of the test step. The sub-control flow has completed execution, including the following steps: When a sub-control flow enters a branch port or an exit port, and the branch port or the exit port is not connected to any port, or the sub-control flow enters the test end step, the sub-control flow is completed. Otherwise, the sub-control flow follows the directed connection and reaches the entry port of the subsequent test step to continue running until it is completed.
