IllegalStateException 抱怨 PowerMockRule 由 powermock 类加载器而不是系统类加载器加载

Question

@RunWith(PowerMockRunner.class)
@PrepareForTest(StaticMethodsHolder.class)

public class MockNTestStaticMethodsHolder {

  @Rule public PowerMockRule rule = new PowerMockRule();

  @Test public void staticSvcClientMethod () {

    // blah blah blah
    mockstatic (StaticMethodsHolder.class);

    expect (StaticMethodsHolder.TomBradyIsStillTheBest()).andReturn(UNQUESTIONABLY);
    expect (StaticMethodsHolder.NEPatriotsStillTheBest()).andReturn(MAYBE);
    expect (StaticMethodsHolder.NEPatriotsLiiWereIdiots()).andReturn(TOTALLY);
    expect (StaticMethodsHolder.NEPatriotsWinsLiii()).andReturn(RU_KIDDING_ME);

  }

}

Maven dependencies/properties 顺序如下：

powermock-version 1.6.6
easymock-version 3.4
easymock
powermock-module-junit4
powermock-api-easymock
powermock-module-junit4-rule-agent （删除它会导致构造函数问题）
powermock-module-junit4-规则（去掉这个依赖没有效果）
powermock-classloading-xstream

运行时错误：

java.lang.IllegalStateException PowerMockRule can only be used
with the system classloader but was loaded by
org.powermock.core.classloader.MockClassLoader.

PowerMock 在咬自己的尾巴。它想使用自己的类加载器，但 JVM 说 PowerMockRule 必须由系统加载。

我该怎么做才能解决这个问题？

Answer 1

您已经在使用PowermockRunner，不需要使用规则。

如果您在使用不同的运行器同时需要作为规则用例的 Powermock 功能。
