使用Powermock测试Spring控制器

问题内容：

我有一个测试特定控制器的类，它可以正常工作

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:config/test-applicationContext-config.xml")
@TestExecutionListeners({ 
    WebContextTestExecutionListener.class, 
    DependencyInjectionTestExecutionListener.class,
    DirtiesContextTestExecutionListener.class })
public class TestAdminController {  
     //.....
}

我在那里使用了来自mockito.org的 Google
Mockito库来模拟我的基础bean。

现在，我的问题如下：
我也需要模拟一些类，但是它们具有final方法，而Google的模拟似乎无法解决此问题。我的一位同事建议使用powermock.org中的Powermock。但这需要使用注解对测试器类进行@RunWith(PowerMockRunner.class)注解。如果使用此方法，则必须删除注释@RunWith(SpringJUnit4ClassRunner.class)，这将给我带来问题，因为将不会创建Spring测试上下文。我如何避免这种情况？

建议后，我已配置为使用PowerMockRule而不是@RunWith注释

我的项目Maven依赖项如下

<dependency>
    <groupId>org.powermock</groupId>
    <artifactId>powermock-mockito-release-full</artifactId>
    <version>1.5</version>
    <type>pom</type>
</dependency> 
<dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-module-junit4-rule</artifactId>
        <version>1.5</version>
        <scope>test</scope>
</dependency>
<dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-classloading-xstream</artifactId>
        <version>1.5</version>
        <scope>test</scope>
</dependency>

现在我的课看起来像这样（另一个控制器测试）

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:config/test-applicationContext-config.xml")
@TestExecutionListeners({ 
    WebContextTestExecutionListener.class, 
    DependencyInjectionTestExecutionListener.class,
    DirtiesContextTestExecutionListener.class })
@PrepareForTest(ADSynchronizationImpl.class)
public class ThirdPartyLoginControllerTest {
    @Rule
    public PowerMockRule rule = new PowerMockRule();

    @Autowired
    private ThirdPartyLoginController thirtPartyLoginController;

    @Autowired
    private MockFactoryForControllers mockFactory;

    @Test
    public void testLoginActiveDirectory(){

    }
}

但是运行测试后，我得到以下异常跟踪

问题答案：

看一下这篇文章，它解释了如何使用PowerMock和SpringJUnit4ClassRunner。基本上，您只需要使用一条特殊PowerMockRule规则：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:config/test-applicationContext-config.xml")
@TestExecutionListeners({ 
    WebContextTestExecutionListener.class, 
    DependencyInjectionTestExecutionListener.class,
    DirtiesContextTestExecutionListener.class })
public class SpringExampleTest {

    @Rule
    public PowerMockRule rule = new PowerMockRule();

}

编辑：似乎其他人与您有同样的问题@PowerMockRule。使用PowerMockAgent可以解决您的情况。
