我正在使用org.springframework.boot.test.OutputCapture来测试记录某些内容的注释。
对于单个测试,如果在源文件中使用输出捕获进行多个测试,则单独运行测试,但是当多个测试一起运行时,只有第一个测试运行获取捕获的输出,其他测试为空字符串。
有什么方法可以避免这种情况,我看不到任何配置可能性吗?
这是一个说明问题的简化测试 import static org.hamcrest.Matchers。; import static org.junit.Assert。;

/**
* Simplest implementation that illustrates my problem using {@link OutputCapture}.
* <p>
* If both tests are run, the second test run will not have any output captured so fails.
* If tests are run individually they both pass.
* <p>
* It is somehow related to
* 1) mocking with mockito which is not actually needed in this simplified implementation: without @InjectMocks no output is captured at all and both test fail.
* 2) if use System.out.println not log4j, both tests pass and output is captured without mocking as well.
