如果抛出JUnit ExpectedException后如何继续测试？ [英] How to continue test after JUnit ExpectedException if thrown?

问题描述

我已经使用ExpectedException功能设置了一些JUnit（4.12）测试，我希望测试在预期的异常之后继续。但是我从来没有看到日志'3'，因为执行似乎在异常后停止，如果捕获事件？

I have set up some JUnit (4.12) test with the ExpectedException feature, and I would like the test to continue after the expected exception. But I never see the log '3', as the execution seems to stop after the exception, event if catch?

这实际上是否可行，以及如何？

Is this actually possible, and how?

@Rule
public ExpectedException exception = ExpectedException.none();

@Test
public void testUserAlreadyExists() throws Exception {
    log.info("1");

    // Create some users
    userService.createUser("toto1");
    userService.createUser("toto2");
    userService.createUser("toto3");
    Assert.assertTrue( userService.userExists("toto1") );
    Assert.assertTrue( userService.userExists("toto2") );
    Assert.assertTrue( userService.userExists("toto3") );

    log.info("2");

    // Try to create an existing user
    exception.expect(AlreadyExistsException.class);
    userService.createUser("toto1");

    log.info("3");
}

推荐答案

你不能这样做，当抛出异常，抛出真实的 ExpectedException 规则。

You cannot do that, when the exception is thrown it's thrown for real, ExpectedException rule or not.

如果你真的想要这种行为，你可以回到旧学校模式：

If you really want this kind of behaviour, you can go back to the "old school" pattern:

try {
    userService.createUser("toto1");
    Assert.fail("expecting some AlreadyExistsException here")
} catch (AlreadyExistsException e) {
    // ignore
}

log.info("3");

但我不会费心去做一些日志。

But I wouldn't bother for some log.
