PowerMockito给出NoClassDefFoundError

Question

我正在尝试使用Mockito和PowerMockito进行单元测试，但它会抛出：

Exception in thread "main" java.lang.NoClassDefFoundError: org/mockito/exceptions/Reporter

每当我尝试进行测试时。这些是我的依赖：

testCompile 'org.mockito:mockito-core:2.8.9'
testCompile 'org.powermock:powermock-api-mockito2:1.6.5'
testCompile 'org.powermock:powermock-module-junit4:1.7.4'

有谁知道如何修理它？

Answer 1

您似乎正在尝试使用不兼容的版本。

根据这个table，您需要使用Powermock的1.7.x版本才能与您的Mockito版本2.8.9兼容。

Answer 2

在external-dependencies.xml-中添加这些依赖项

<dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-api-support</artifactId>
        <version>1.5.6</version>
    </dependency>
    <dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-reflect</artifactId>
        <version>1.5.6</version>
    </dependency>
    <dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-api-mockito</artifactId>
        <version>1.5.6</version>
    </dependency>
    <dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-module-junit4</artifactId>
        <version>1.5.6</version>
    </dependency>
    <dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-module-junit4-common</artifactId>
        <version>1.5.6</version>
    </dependency>

Explanation-

1. powermock 1.5.6与junit 4.12有问题 - 这需要

   powermock
   1.6.1 :: org.powermock.reflect.exceptions.FieldNotFoundException

   ：在课堂上找不到Field'fTestClass'
2. org.junit.internal.runners.MethodValidator powermock 1.6.1需要更多当前的mockito ::在接口org.mockito.internal.util.MockitoSpy的类层次结构中找不到与名称add匹配的方法。
3. 切换到powermock 1.6.2与升级的mockito到1.10.8 ::结果java.lang.NoClassDefFoundError：org/mockito/internal/creation/util/MockitoMethodProxy切换到mockito-core 1.10.19和org.powermock 1.6.4
