我们知道，PowerMock提供了3个不同的执行方式以支持不同版本的JUnit，包括JUnit4.4+, JUnit4.0~4.3和JUnit3。
那么在Maven测试项目中，如何根据不同的JUnit版本，配置pom.xml文件以使用PowerMock的Mockito扩展呢？
1. 对于JUnit4.4+，示例如下：
<properties>
<powermock.version>1.6.5</powermock.version>
</properties>
<dependencies>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>
</dependencies>
2. 对于JUnit4.0~4.3
<properties>
<powermock.version>1.6.5</powermock.version>
</properties>
<dependencies>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4-legacy</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>
</dependencies>
3. 对于JUnit3
<properties>
<powermock.version>1.6.5</powermock.version>
</properties>
<dependencies>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit3</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>
