grails - 何时使用 mock 以及何时使用带有 spock 的 stub？

Question

我想了解更多在 Grails 文档中找到的这句话:

If the test is concerned with proving that the test subject interacts with a collaborator in a particular way, use a mock. If the fact that a collaborator behaves in a certain way exposes a particular behavior in the test subject the outcome of that behavior is what you are testing, use a stub

Answer 1

如果您想测试某个方法将被调用多少次，请使用 模拟 :

2 * yourService.someMethod(*_) // test that someMethod will be called 2 times

如果没有 - 使用 stub
