JUnit 失败回调/方法 [英] JUnit on failure callback/method

问题描述

是否有可能在测试用例或断言失败时触发方法，以便在测试用例失败时执行某些操作(例如 UI 测试时的屏幕截图、编写错误日志等...).

Is there any possibility to trigger a method whenever a testcase or assertion fails, in order to do some things when a testcase fails (e.g. Screenshot while UI-Testing, writing an error log, and so on...).

也许有注释之类的东西，我还没注意到.

Maybe there is something like an annotation, I did not yet notice.

提前致谢！

推荐答案

您可以使用 TestWatcher 规则并实现您自己的 failed 方法来截取屏幕截图或任何您想要的需要在测试失败时做.来自官方文档的略微修改示例::>

You can use the TestWatcher rule and implement your own failed method to take a screenshot or whatever you need to do upon test failure. Slightly modified example from the official documentation:

public static class WatchmanTest {
    private static String watchedLog;

    @Rule
    public TestRule watchman = new TestWatcher() {
        @Override
        protected void failed(Throwable e, Description description) {
            watchedLog += d + "\n";
            // take screenshot, etc.
        }
    };

    @Test
    public void fails() {
        fail();
    }
}
