TestNG是否支持JUnit4的@Rule之类的东西? [英] Does TestNG support something like JUnit4's @Rule?

问题描述

TestNG是否具有类似@Rule的东西?我正在特别考虑:

Does TestNG have something like @Rule? I am thinking specifically about:

@Rule public TemporaryFolder folder = ...

甚至

@Rule public MethodRule globalTimeout = new Timeout(20);

我知道我可以使用setUp()和tearDown()等效项手动实现这些操作，但是这些并不能为我提供使用@Rule所带来的便利.

I am aware that I can manually implement these things using setUp() and tearDown() equivalents, but these don't give me the convenience that I get using @Rule.

推荐答案

规则非常容易模仿，例如使用超级类:

Rules are pretty easy to emulate, for example with super classes:

public void Base {
  @BeforeMethod
  public void createTempDir() { ... }

  @AfterMethod
  public void deleteTempDir() { ... }
}

public void MyTest extends Base {
  @Test
  ...
}

如果扩展Base，将始终自动创建一个临时目录，然后将其删除.

If you extend Base, a temporary directory will always be automatically created and then deleted.

与Rule相比，此方法的优点是Rule始终在类范围内，而使用TestNG时，您可以在方法，测试，类，组甚至套件周围实现它们.

The advantage of this approach over Rules is that Rules are always class scoped, while with TestNG, you can implement them around methods, tests, classes, groups and even suites.
