Test data generation method and device, controller and medium

The invention relates to a test data generation method and device, a controller and a medium. The method comprises the steps of obtaining test demand information; analyzing the test demand information, and generating a corresponding test instruction; and calling a pre-stored interface test case and/or test script according to the test instruction to generate test data. Test data can be rapidly generated according to user requirements, the manual operation time is shortened, the test cost is reduced, and the test efficiency is improved. 本发明涉及一种测试数据生成方法、装置以及控制器和介质，所述方法包括:获取测试需求信息；解析所述测试需求信息，并生成对应的测试指令；根据所述测试指令调取预先存储的接口测试用例和/或测试脚本生成测试数据。本发明能够根据用户需求快速生成测试数据，减少人工操作时间，降低测试成本，提高测试效率。
