使用Powermock测试Spring控制器
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 { //..... } 我使用了mockito.org上的Google的Mockito库来模拟我的底层bean。
现在我的问题是：我有一些类需要被嘲笑，但他们有final方法，谷歌的mockito似乎没有解决这个问题。 我的一位同事建议使用powermock.org上的Powermock 。 但它需要使用@RunWith(PowerMockRunner.class)注释来注释测试器类。 如果我使用这个，我必须删除注释@RunWith(SpringJUnit4ClassRunner.class) ，这将给我带来问题，因为不会创建Spring测试上下文。 我怎么能避免这种情况？
建议我配置使用PowerMockRule而不是@RunWith注释
我的项目Maven依赖项如下
org.powermock powermock-mockito-release-full 1.5 pom org.powermock powermock-module-junit4-rule 1.5 test org.powermock powermock-classloading-xstream 1.5 test
现在我的class级看起来像这样（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(){ } }
但在运行我的测试后，我得到以下exception跟踪

看看这篇文章 ，它解释了如何使用PowerMock和SpringJUnit4ClassRunner 。 基本上，您只需使用特殊的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：似乎其他人遇到的问题与@PowerMockRule 相同 。 使用PowerMockAgent可以解决您的问题。 另见SO上的这个问题 。
您可以使用JMockit而不是Powermock。 它可以完成Powermock可以执行的所有操作，并且它不需要@RunWith子句，因此它不会干扰您的Spring测试运行器。 我发现PowerMockRule引入了比解决的问题更多的问题……
您也可以尝试使用注释来测试您的测试类
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)
见这里的例子。
