本文探讨了JUnit测试中出现“no runnable methods”错误的原因及解决办法。常见问题包括测试类未使用@Test注解、Spring注入所需的@Required设置器未设置、Mock对象初始化不当以及同一类被多次模拟。

This error is a catchall for anything else that might be wrong with your test class. First make sure any of the below problems are not occurring.

Your unit test code is running JUnit4. At least one test method must have the @Test annotation. Otherwise this error occurs.

If the class you are testing has @Required setters for Spring injections they must be set otherwise JUnit will mask the missing required exception as a no runnable methods exception.

If you are initializing your mock objects outside of the @Begin method you will get this error.

If you are attempting to mock the same class more than once you will get this error.
