Method and device for testing transmission control unit software

The invention provides a test method and device for transmission control unit software, and the method comprises the steps: determining the test weight of each test item in different test scenes; according to the test weight of each test item, calculating the fault rate of the to-be-tested software in different test scenes; and determining a target test scheme according to the fault rate in each test scene. According to the test method and device for the transmission control unit software, the test weight of each test item is determined by combining previous actual faults, test results and the like, the fault rates of the to-be-tested software in different test scenes are calculated through the test weights, the target test scheme is finally determined according to the fault rates, and the test efficiency is improved. Based on the target test scheme and the total test time, a tester can more accurately distribute the test time required by each test scene and the number of times of repeated tests, the test tim
