Abstract
Description
Technical Field
[0001] This invention relates to the field of digital testing of equipment software, and specifically to a method and apparatus for testing a closed-loop digital system of equipment software. Background Technology
[0002] Software testing plays a crucial role in equipment software development. It improves software reliability, stability, and execution efficiency, leading to continuous improvement in equipment software quality. Equipment software system testing, which verifies the compatibility between various software functions at the system level, greatly helps ensure the software correctly fulfills system requirements and is an essential step in equipment software verification.
[0003] Digital software testing technology uses digital means to provide virtual hardware resources for operating equipment software, which can ensure the full implementation of software testing methods without affecting the physical equipment, thus effectively solving the problem of insufficient testing capabilities for equipment software systems.
[0004] Currently, there is no closed-loop system testing digital architecture that can be flexibly configured according to the needs of equipment software testing. This makes the cost of conducting equipment software system testing extremely high, and it is also impossible to fully implement testing methods, resulting in poor testing results. Summary of the Invention
[0005] To address the shortcomings of existing technologies, the present invention aims to provide a method and apparatus for testing a digital closed-loop system of equipment software, which can effectively solve the problem of limited physical testing environment resources and difficulty in ensuring the adequacy of testing.
[0006] To achieve the above objectives, the present invention provides a testing method for a digital closed-loop system of equipment software, which specifically includes the following steps:
[0007] Digital virtual machines and soft buses are created in a digital testing environment to run different types of equipment under test (EUT) software and supporting components based on different hardware platforms together in a digital testing environment for system testing.
[0008] Based on the created digital virtual machine, a digital operating environment is provided for the software system of the equipment under test;
[0009] Based on the created soft bus interface, the communication data of the equipment under test software and the test components are encapsulated and transmitted through the soft bus.
[0010] Establish a control mechanism and, based on this mechanism, perform unified clock control on each test node in the digital testing environment to control the service operation rate and communication transmission rate of each test node.
[0011] Based on the above technical solution, the nodes participating in system testing in the digital testing environment include multiple types, namely, the first type node, the second type node, the third type node, the fourth type node, and the fifth type node.
[0012] Based on the above technical solution, the first type of node is used to run embedded equipment under test software to simulate the CPU processor and communication chip by digital means. The first type of node is also used to realize data communication through the interface soft bus and to accept the control mechanism to control the clock.
[0013] Based on the above technical solution, the second type of node is a DLL link library. Based on the DLL link library, closed-loop control logic or test tools participate in the testing work. The second type of node is also used to realize data communication through the interface soft bus and to accept the control mechanism to control the clock.
[0014] Based on the above technical solution, the third type of node is an exe executable file. Based on the exe executable file, non-embedded equipment software with a human-computer interaction interface participates in the testing work. The third type of node is also used to realize data communication through the interface soft bus and to accept the control mechanism to control the clock.
[0015] Based on the above technical solution, the fourth type of node is a hardware / software signal switching node, which is used to convert real hardware signals into digital signals that can be recognized and used by the soft bus, and output a synchronous clock to the real hardware device to drive the physical device to participate in the testing work. The fourth type of node is also used to realize data communication by interfacing with the soft bus and to accept the control mechanism to control the clock.
[0016] Based on the above technical solution, the fifth type node is a test control node, used to control the test process and set test parameters. Only one fifth type node can be set in each digital closed-loop system test environment. The fifth type node is also used to realize data communication through the interface soft bus and to accept the control mechanism to control the clock.
[0017] Based on the above technical solution, the equipment software digital closed-loop system is a test equipment software system composed of embedded test equipment software, non-embedded test equipment software and closed-loop control logic DLL link library, which can be composed of first type nodes, second type nodes and third type nodes.

[0023] The nodes participating in system testing in the digital testing environment include multiple types, namely, type 1 nodes, type 2 nodes, type 3 nodes, type 4 nodes, and type 5 nodes.
[0024] The first type of node is used to run embedded equipment under test software to simulate the CPU processor and communication chip by digital means. The first type of node is also used to realize data communication through the interface soft bus and to accept the control mechanism to control the clock.
[0025] The second type of node is a DLL link library. Based on the DLL link library, closed-loop control logic or test tools participate in the testing work. The second type of node is also used to realize data communication through the interface soft bus and to receive the control mechanism to control the clock.
[0026] The third type of node is an executable file (exe). Based on the executable file, non-embedded equipment software with a human-machine interface participates in the testing work. The third type of node is also used to realize data communication through a soft bus and to receive clock control from the control mechanism.
[0027] The fourth type of node is a hardware / software signal switching node, which is used to convert real hardware signals into digital signals that can be recognized and used by the soft bus, and output a synchronous clock to the real hardware device to drive the physical device to participate in the testing work. The fourth type of node is also used to realize data communication by interfacing with the soft bus and to accept the control mechanism to control the clock.
[0028] The fifth type of node is a test control node, used to control the test process and set test parameters. Only one fifth type of node can be set in each digital closed-loop system test environment. The fifth type of node is also used to realize data communication through the interface soft bus and to accept the control mechanism to control the clock.
[0029] Compared with existing technologies, the advantages of this invention are as follows: A digital virtual machine and a soft bus are created in a digital testing environment to allow different types of equipment under test (DUT) software and accompanying test components based on different hardware platforms to run together in a single digital testing environment for system testing. Based on the created digital virtual machine, a digital operating environment is provided for the DUT software system.
