我有一个测试特定控制器的类，它工作正常

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

我在那里使用来自mockito.org的 Google 的 Mockito 库来模拟我的底层 bean。

现在我的问题如下：我有一些类也需要模拟，但它们有final方法，谷歌的模拟似乎没有解决这个问题。我的一位同事建议使用 powermock.org 的Powermock。但它需要用注释来注释测试器类@RunWith(PowerMockRunner.class)。如果我使用它，我必须删除注释@RunWith(SpringJUnit4ClassRunner.class)，这会给我带来问题，因为不会创建 Spring 测试上下文。我怎样才能避免这种情况？

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(){

    }
}

但是在运行我的测试之后，我得到了以下异常跟踪

看看这篇文章，它解释了如何使用 PowerMock 和SpringJUnit4ClassRunner. 基本上，你只需要使用一个特殊的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：其他人似乎和你有同样的问题@PowerMockRule。改用 PowerMockAgent可以解决您的问题。另请参阅SO 上的这个答案。

您也可以尝试使用注释您的测试类

@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)

请参见此处的示例。

您可以使用 JMockit 而不是 Powermock。它可以做 Powermock 可以做的所有事情，而且它不需要 @RunWith 子句，因此它不会干扰您的 Spring 测试运行器。我发现 PowerMockRule 引入的问题多于它解决的问题......
