Question

我遇到PowerMock和Mockito兼容性问题。

我有测试班：

@ActiveProfiles("test")
@PrepareForTest(LanguageUtils.class)
public class MyControllerTest {

    @Mock
    private MyMockClass MyMockClass;    
    @Autowired
    private MyController myController;

    @Rule
    public PowerMockRule rule = new PowerMockRule();
}

我的POM看起来像：

    <junit-version>4.12</junit-version>
    <hamcrest-version>1.3</hamcrest-version>
    <mockito-version>1.10.19</mockito-version>      
    <powermock-version>1.6.4</powermock-version>

    <dependency>
        <groupId>org.hamcrest</groupId>
        <artifactId>hamcrest-all</artifactId>
        <version>${hamcrest-version}</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.mockito</groupId>
        <artifactId>mockito-core</artifactId>
        <version>${mockito-version}</version>
        <exclusions>
            <exclusion>
                <artifactId>hamcrest-core</artifactId>
                <groupId>org.hamcrest</groupId>
            </exclusion>
        </exclusions>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-api-mockito</artifactId>
        <version>${powermock-version}</version>
        <scope>test</scope>
    </dependency>

    <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-module-junit4-rule</artifactId>
        <version>${powermock-version}</version>
        <scope>test</scope>
    </dependency>

当我尝试运行测试时，我得到了ClassNotFoundException。错误导致PowerMockRule，因为当我删除此行时，错误消失。

完整的堆栈跟踪看起来像：

这是PowerMock的一个已知问题（请参阅，例如bug 597）。简而言之，如果您使用规则代理模块替换规则模块，它应该可以解决问题。即，替换此要求：

<dependency>
    <groupId>org.powermock</groupId>
    <artifactId>powermock-module-junit4-rule</artifactId>
    <version>${powermock-version}</version>
    <scope>test</scope>
</dependency>

使用：

<dependency>
    <groupId>org.powermock</groupId>
    <artifactId>powermock-module-junit4-rule-agent</artifactId>
    <version>${powermock-version}</version>
    <scope>test</scope>
</dependency>

抛出PowerMockRule ClassNotFoundException
