issues while using @RunWith Annotation and powerMock
提问by Bhuvan
Initially I was using only Mockito in junits so I was using SpringJUnit4ClassRunner.class in @RunWith annotation ie
最初我只在 junits 中使用 Mockito，所以我在 @RunWith 注释中使用 SpringJUnit4ClassRunner.class，即
@RunWith(SpringJUnit4ClassRunner.class)
due to which spring dependency injection was working fine and was getting a bean through
由于哪个 spring 依赖注入工作正常并且正在通过一个 bean
@Autowired
Someservice someservice ;
But now, I have also integrated PowerMock in it.
但是现在，我也将 PowerMock 集成到其中。
So as per doc, I have replaced class mentioned in @RunWith annotation with
因此，根据doc，我已将 @RunWith 注释中提到的类替换为
@RunWith(PowerMockRunner.class)
but now, someservice is coming out to be null. Is there a way to use both SpringJUnit4ClassRunner.classand PowerMockRunner.classin @RunWith annotation
但是现在，someservice 出来是空的。有没有办法在@RunWith 注释中同时使用SpringJUnit4ClassRunner.class和PowerMockRunner.class

You have to use the PowerMockRule.
您必须使用PowerMockRule。
@RunWith(SpringJUnit4ClassRunner.class)
@PrepareForTest(X.class)
public class MyTest {
@Rule
public PowerMockRule rule = new PowerMockRule();
// Tests goes here
...
}
For a full example of the Spring Integration Test with PowerMock and Mockito, you could checkout this maven project.
有关使用 PowerMock 和 Mockito 的 Spring 集成测试的完整示例，您可以查看这个maven 项目。
svn co http://powermock.googlecode.com/svn/tags/powermock-1.4.12/examples/spring-mockito/
cd spring-mockito/
Look at the dependecies to powermock.
查看 powermock 的依赖项。
less pom.xml
and then run the test
然后运行测试
mvn test
and you should get the following test results :
你应该得到以下测试结果：
Tests run: 4, Failures: 0, Errors: 0, Skipped: 0

I know this thread is old, but it's good to add that since 2014 and this pull request, you can use the @PowerMockRunnerDelegateannotation to "delegate" the run context to SpringJUnit4ClassRunner(or any other runner really).
我知道这个线程很旧，但是很高兴添加自 2014 年和这个pull request以来，您可以使用@PowerMockRunnerDelegate注释将运行上下文“委托”给SpringJUnit4ClassRunner（或任何其他运行器）。
Above code would look like :
上面的代码看起来像：
@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
@PrepareForTest(X.class);
public class MyTest {
// Tests goes here
...
}
With this annotation, you don't need the PowerMock rule anymore !
有了这个注解，你就不再需要 PowerMock 规则了！
