Automatic test method of heterogeneous model integration system based on virtual bus

The invention discloses an automatic test method of a heterogeneous model integration system based on a virtual bus in the technical field of airborne system integration simulation testing, which comprises the following steps: a test script generator loads a test case and analyzes test case data to generate a corresponding test script file; the test script analyzer analyzes and executes the test script file, converts test input into data excitation of the virtual bus, and inputs the data excitation into the virtual bus; the test script parser parses and executes the test script file, obtains test result data from the virtual bus, and judges the correctness; and the test script analyzer counts and corresponds one by one to generate a test result report. According to the automatic test method, automation from test cases to test result judgment is achieved through automatic script generation and execution, automatic test result judgment and automatic test report generation, the automation level of heterogeneous
