Test case layout method and device based on to-be-tested line intersection information

The invention provides a test case layout method and device based on to-be-tested line intersection information. The method comprises the following steps: extracting actual scene elements and positionattributes in the to-be-tested line intersection information; querying an intersection scene database based on the actual scene elements to determine a template position scene corresponding to the intersection scene to which the to-be-tested line belongs; determining an actual position scene contained in the to-be-tested line based on the position attribute of the to-be-tested line and a templateposition scene corresponding to the intersection scene to which the to-be-tested line belongs; and processing the test cases contained in each actual position scene based on a preset deduplication rule, and determining the test cases needing to be tested in each actual position scene, the intersection scene database comprising pre-stored template intersection scenes, template position scenes andcorresponding relationships among the test cases. According to the method and the device provided by the invention, the test task completion efficiency is improved, the task time consumption is reduced, and the waste of manpower and material resources caused by repeated test of the same test case in the same road crossing scene can be avoided.
