BRIEF DESCRIPTION OF THE DRAWINGS
[0024] Figure 1 is a block diagram of a test system for updating test information in real time according to an embodiment of the present invention;
[0025] Figure 2 It is a flow chart of a test method for updating test information in real time according to an embodiment of the present invention. DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0027] A test system for updating test information in real time according to an embodiment of the present invention is designed with a layered architecture, including a data access layer, a business logic layer and a presentation layer.
[0028] The data access layer is used to initialize the data interface board and provide the data input and output interface of the data interface board. For example, during the test process, the DIO interface, AD / DA interface and CAN interface are accessed to realize data input (DI, AD, receiving CAN messages) and data output (DO, DA, sending CAN messages).
[0029] The business logic layer is used to encapsulate the test class according to the test requirements of the product to be tested. The test class is used to interact with the product to be tested through the data input and output interface. That is, the business logic is encapsulated according to the single machine technical requirements, and data is interacted with the single machine under test through the data access layer.
[0030] The presentation layer is used to encapsulate the human-machine operation interface and the test function management interface.
[0031] When executing the test, the presentation layer in the main thread creates the test tree and test thread according to the user's test configuration input. The main thread completes system initialization, test thread creation, and display and saves test information; the test thread mainly performs tests according to the encapsulated business logic process.
[0032] The business logic layer traverses and executes the test threads, implements the test of the product to be tested through the test class, and sends the test process information and test result information to the presentation layer through a blocking message mechanism for storage and display.
[0033] Preferably, the blocking message mechanism means that after sending the specified test process information or test result information to the main thread, the test items after the current test item are continued to be executed until the message that the main thread has processed the specified test process information or test result information and displayed it on the interface is received. Specifically, the specified message is sent to the specified window through the SendMessage function of MFC until the receiving window program processes the message and returns to execute the subsequent program.
[0034] Preferably, the test result information includes the conclusions of the test items and information of concern to the user; the test process information includes the operation information performed during the test process and the information received by the business logic layer.
[0035] The working principle of the test system is as follows: the presentation layer provides an interface for users to configure test information. After the user clicks "Start Test", a test tree is generated. During the test, the test item status (green for normal, red for abnormal), test process information and test result information in the test tree are updated in real time. After the test, the user is prompted to enter the test information and save the test data. The business logic layer encapsulates the business logic according to the technical requirements of the single machine, that is, according to the required process, the board operation interface provided by the data access layer is used to input the switch quantity / voltage / control instructions, etc. to the single machine under test. The state information (switch quantity / voltage / status message, etc.) fed back by the single machine under test is collected through the data access layer, and the information is interpreted as required, so as to realize the function, performance and interface verification of the single machine under test. During the test, the test process information (action instructions and status information) and result information (test items and test conclusions) are sent to the presentation layer in real time for display and output. The data access layer provides the initialization function of the DIO board, AD / DA board and CAN board, and provides the input and output interfaces of the above boards to realize the interaction with the single machine during the test.
[0036] like Figure 1 As shown, the presentation layer includes the following classes: operation interface class, test tree class, real-time information class, test record class, and test information class.
[0037] The operation interface class is responsible for managing the test configuration interface and receiving the user's test configuration input, such as selecting the product to be tested, clicking to start the test, etc.
[0038] The test tree class is used to display the status of each test item in the test tree on the interface according to the received test process information or test result information. For example, all test items of the tested product selected by the operator are displayed in the form of a tree in the interface, and after the test starts, the test items are marked with different colors (yellow - executing, red - test abnormality, green - test normal), so that the tester can view the test information intuitively.
[0039] The real-time information class is used to display the received test process information in the real-time information box.
[0040] The test record class is used to display the received test result information in the test record box.
[0041] The test information class is used to save test-related information and can be called after the test is completed, such as the product code, number, test time, test location, tester, etc.
[0042] The business logic layer includes the following classes: a common test class, a self-test class, and one or more product test classes (eg, a product A test class and a product B test class).
[0043] The test common class is the parent class of the self-test class and the product test class, and is used to manage common properties and methods, such as parent class and child class object conversion, calling and executing tree structure test items, output switch quantity, input switch quantity, output DA, read AD, send CAN message, read CAN message, etc.
[0044] The self-test class and product test class inherit from the test common class and have the common properties and methods of the parent class. In addition, methods such as test item initialization, test tree construction, and test functions are defined according to the test requirements.
[0045] The data access layer includes the following classes: driver management class and test exception class. The driver management class is responsible for opening and closing all boards and providing board access interface functions, such as DO output, DI input, DA output, AD input, and sending and receiving CAN messages; the test exception class sends the exceptions encountered during board access to the business logic layer and displays them on the interface through a pop-up box to prompt the operator, such as: board opening failure, DO output exception, CAN sending exception, etc.
[0046] A test system for real-time updating of test information provided by an embodiment of the present invention adopts a "layered" concept for architectural design, thereby improving the maintainability and portability of the system; adopts multi-threading technology to realize real-time display of test information and improve the efficiency of fault location; and adopts "blocking" message mapping instead of "non-blocking" message mapping, thereby effectively preventing the problem of illegal memory access that may be caused by multiple threads operating the message memory at the same time.

[0048] S1, initialize the data interface board and provide the data input and output interface and abnormal feedback interface of the data interface board;

[0051] S4, start the main thread. After the user clicks to start the test, create a test tree and test thread in the main thread according to the user's test configuration input;
