Question

我在Android Studio中有一个项目。我想用Mockito和PowerMock框架测试一些功能。 Powermock在简单测试中给出初始化错误，如下所示：

java.lang.NoClassDefFoundError: org/powermock/reflect/proxyframework/ClassLoaderRegisterProxyFramework

我收到错误：

testCompile files('libs/mockito-all-2.0.2-beta.jar')
testCompile files('libs/mockito-core-2.0.5-beta.jar')
testCompile files('libs/powermock-api-mockito-1.6.5.jar')

testCompile files('libs/javassist-3.14.0-ga-1.0.0.jar')
testCompile files('libs/cglib-2.2.2.jar')

我已检查过我的依赖项版本：

Mockito运作良好，但Powermock仍然出错。

请帮助

Answer 1

我添加了一个依赖项：testCompile files('libs/powermock-reflect-1.6.5.jar')。

我还将javassist的版本更改为：testCompile files('libs/javassist-3.18.2-GA.jar')。

它解决了我的问题。

简单的PowerMock测试给出了一个错误，android studio项目
