使用 Powermock 測試 Spring 控制器

Question

我有一個測試特定控制器的類，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 {  
     //.....
}

我在那里使用了來自mockito.org 的Google 的 Mockito 庫來模擬我的底層 bean。

現在我的問題如下：我有一些類也需要模擬，但它們有final方法，而谷歌的模擬似乎沒有解決這個問題。 我的一位同事建議使用來自powermock.org 的 Powermock 。 但是它需要使用@RunWith(PowerMockRunner.class)注釋來注釋測試器類。 如果我使用它，我必須刪除注釋@RunWith(SpringJUnit4ClassRunner.class)這會給我帶來問題，導致不會創建 Spring 測試上下文。 我怎樣才能避免這種情況？

建議后，我已配置為使用PowerMockRule而不是@RunWith注釋

我的項目Maven依賴如下

<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>

現在我的班級看起來像這樣（另一個控制器測試）

@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(){

    }
}

但是在運行我的測試后，我得到以下異常跟蹤

Answer 1

看看這篇文章，它解釋了如何使用 PowerMock 和SpringJUnit4ClassRunner 。 基本上，你只需要使用一個特殊的PowerMockRule規則：

@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();

}

編輯：在@PowerMockRule方面，其他人似乎和你有同樣的問題。 改用PowerMockAgent可以解決您的問題。 另請參閱 SO 上的這個答案。

Answer 2

您也可以嘗試使用

@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)

請參閱此處的示例。

Answer 3

您可以使用 JMockit 而不是 Powermock。 它可以完成 Powermock 可以做的所有事情，並且不需要 @RunWith 子句，因此它不會干擾您的 Spring 測試運行程序。 我發現 PowerMockRule 引入的問題多於它解決的問題......
