无法使用PowerMockRunner运行JUnit测试

本文介绍了无法使用PowerMockRunner运行JUnit测试的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我有一个基于Gradle的Java项目，现在我想使用PowerMock来模拟一个私有的方法。问题是我不能使用PowerMockRunner，因为我添加 @RunWith（org.powermock.modules.junit4.PowerMockRunner.class）注释。

错误：

org.powermock.reflect。 exceptions.FieldNotFoundException：在org.junit.internal.runners.MethodValidator类中找不到字段'fTestClass'。 在org.powermock.reflect.internal.WhiteboxImpl.getInternalState（WhiteboxImpl.java:581）在org.powermock.reflect.Whitebox.getInternalState（Whitebox.java:308）在org .powermock.modules.junit4.internal.impl.testcaseworkaround.PowerMockJUnit4MethodValidator.validate TestMethods（PowerMockJUnit4MethodValidator.java:79）在org.powermock.modules.junit4.internal.impl.testcaseworkaround.PowerMockJUnit4MethodValidator.validate InstanceMethods（PowerMockJUnit4MethodValidator。 java：49）在org.junit.internal.runners.MethodValidator.validateMethodsForDefaultRunner（MethodValidator.java:51）在org.powermock.modules.junit4.internal.impl.PowerMockJUnit44RunnerDelegateImpl.validate（PowerMockJUnit44RunnerDelegateImpl。 java：108） ...

这是我的测试依赖项：

testCompile'junit：junit：4. +'，'org.powermock：powermock-core：1.5.6'，'org.powermock：powermock-module-junit4：1.5。 6'，'org.powermock：powermock-api-mockito：1.5.6'

测试本身也完全失效（初始化错误）失败：

@RunWith（PowerMockRunner.class） public class SomeTest { @Test public void testSomething（）{} }

任何想法可能是错的？使用PowerMock的其他测试工作正常（没有人使用PowerMockRunner）。

请问和谢谢任何帮助！ 本

解决方案

这是一个错误，当您使用JUnit 4.12和PowerMock& 1.6.1。在PowerMock 1.6.1中解决了这个问题。请相应地更新您的依赖关系

testCompile'junit：junit：4.12'，'org.powermock：powermock-core ：1.6.1'，'org.powermock：powermock-module-junit4：1.6.1'，'org.powermock：powermock-api-mockito：1.6.1'

如果您无法升级PowerMock，则可以使用JUnit 4.11。

testCompile'junit：junit：4.11'，'org.powermock：powermock-core：1.5.6'，'org.powermock：powermock-module- junit4：1.5.6'，'org.powermock：powermock-api-mockito：1.5.6'

你可以添加更多的stacktrace行，这样可以发现更多有关问题的细节。

I have a Gradle based Java project were I now want to mock a private method using PowerMock. The problem is that I am not able to use the PowerMockRunner as I always get the following exception when I add the @RunWith(org.powermock.modules.junit4.PowerMockRunner.class) annotation.

Error:

org.powermock.reflect.exceptions.FieldNotFoundException: Field 'fTestClass' was not found in class org.junit.internal.runners.MethodValidator. at org.powermock.reflect.internal.WhiteboxImpl.getInternalState(WhiteboxImpl.java:581) at org.powermock.reflect.Whitebox.getInternalState(Whitebox.java:308) at org.powermock.modules.junit4.internal.impl.testcaseworkaround.PowerMockJUnit4MethodValidator.validate TestMethods(PowerMockJUnit4MethodValidator.java:79) at org.powermock.modules.junit4.internal.impl.testcaseworkaround.PowerMockJUnit4MethodValidator.validate InstanceMethods(PowerMockJUnit4MethodValidator.java:49) at org.junit.internal.runners.MethodValidator.validateMethodsForDefaultRunner(MethodValidator.java:51) at org.powermock.modules.junit4.internal.impl.PowerMockJUnit44RunnerDelegateImpl.validate(PowerMockJUnit44RunnerDelegateImpl.java:108) ...

This are my test dependencies:

testCompile 'junit:junit:4.+', 'org.powermock:powermock-core:1.5.6', 'org.powermock:powermock-module-junit4:1.5.6', 'org.powermock:powermock-api-mockito:1.5.6'

The test itself fails also when completely empty (initialization error):

@RunWith(PowerMockRunner.class) public class SomeTest { @Test public void testSomething() { } }

Any ideas what might be wrong? Other tests using PowerMock are working fine (none of them uses the PowerMockRunner).

Greetings and thanks for any help! Ben

解决方案

This is a bug that occurs when you use JUnit 4.12 and PowerMock < 1.6.1. The problem is solved in PowerMock 1.6.1. Please update your dependencies accordingly

testCompile 'junit:junit:4.12', 'org.powermock:powermock-core:1.6.1', 'org.powermock:powermock-module-junit4:1.6.1', 'org.powermock:powermock-api-mockito:1.6.1'

If you cannot upgrade PowerMock then you can use JUnit 4.11.

testCompile 'junit:junit:4.11', 'org.powermock:powermock-core:1.5.6', 'org.powermock:powermock-module-junit4:1.5.6', 'org.powermock:powermock-api-mockito:1.5.6'

Could you please add further lines of the stacktrace, which uncover more details about the problem.
