Automatic test method based on embedded software simulator

Abstract

An automated test method based on an embedded software simulator comprises the following steps: step S0, creating an automated test script module to prepare for test requirements; Step S1: according to the function provided by the emulator API module, the test logic conforming to the software under test is written in the automated test script module, the emulator API module includes address bus read and write, register read and write, memory read and write, program breakpoint, conditional breakpoint, symbol table, emulator control, simulation time, simulation timer, and / or trigger interrupt. 2, loading the automated t script module into the simulator software; 3, starting the emulator software and executing the automate test script module; S4, verifying the correctness of the code logic ofthe automated test script module and making adjustment and modification; 5, if that step S4 is passed, executing and operating the embedded software automation test through the automation test scriptmodule; Step S6: the test is complete. Makes program debugging controllable, changeable, and quick to locate program logic errors.

Description

technical field [0001] The invention relates to an automated testing method for computer software, in particular to an automated testing method based on an embedded software emulator. Background technique [0002] At present, the embedded software emulators on the market can only manually control the emulator software in the process of testing the target software, such as manually executing the start and stop of the program; Numerical values ​​or injecting faults into certain memory addresses to test and observe system execution behavior can only be achieved through manual modification by the tester; and if you want to test the software through fault injection at a specific moment, human operations are often inaccurate Controlling the time will lead to deviations in the injection time and affect the test results. There are defects of low efficiency and cumbersome operation in testing the target software through artificial control. [0003] Aiming at the problems of low effi...

There are defects in the low efficiency and cumbersome operation of testing the target software through artificial control.

[0003] Aiming at the problems of low efficiency and cumbersome operation of the embedded software emulator to debug the target software existing in the prior art, no effective solution has been proposed in the prior art
