TestNG 依赖于不同类的方法

2022-01-14 00:00:00 testing automated-tests java junit testng

@Test 注释的 dependsOnMethods 属性在要依赖的测试与具有此注释的测试属于同一类时正常工作.但是如果要测试的方法和依赖的方法在不同的类中，则不起作用.示例如下:

The dependsOnMethods attribute of the @Test annotation works fine when the test to be depended upon is in the same class as that of the test that has this annotation. But it does not work if the to-be-tested method and depended-upon method are in different classes. Example is as follows:

class c1 {
  @Test
  public void verifyConfig() {
    //verify some test config parameters
  }
}

class c2 {
  @Test(dependsOnMethods={"c1.verifyConfig"})
  public void dotest() {
    //Actual test
  }
}

有没有办法绕过这个限制?一种简单的方法是在 class c2 中创建一个调用 c1.verifyConfig() 的测试.但这将是太多的重复.

Is there any way to get around this limitation? One easy way out is to create a test in class c2 that calls c1.verifyConfig(). But this would be too much repetition.

推荐答案

把方法放在一个group中，使用dependsOnGroups.

Put the method in a group and use dependsOnGroups.

class c1 {
  @Test(groups={"c1.verifyConfig"})
  public void verifyConfig() {
    //verify some test config parameters
  }
}

class c2 {
  @Test(dependsOnGroups={"c1.verifyConfig"})
  public void dotest() {
    //Actual test
  }
}

建议在 @Before* 中验证配置并在出现问题时抛出，这样测试就不会运行.这样，测试就可以专注于测试.

It is recommended to verify configuration in a @Before* and throw if something goes wrong there so the tests won't run. This way the tests can focus on just testing.

class c2 {
  @BeforeClass
  public static void verifyConfig() {
    //verify some test config parameters
    //Usually just throw exceptions
    //Assert statements will work
  }

  @Test
  public void dotest() {
    //Actual test
  }
}
