Question

尝试从我的代码中使用JUnit运行PowerMock测试时遇到麻烦。这是我加载和运行测试类的方式：

        URL[] urls = getTargetClassesUrls();

        try (URLClassLoader cl = new URLClassLoader(urls, Test.class.getClassLoader())) {

            Class clazz = cl.loadClass(className);

            return JUnitCore.runClasses(clazz);

这是我希望JUnit运行的类：

@PrepareForTest(System.class)
public class MyTest {

  static {PowerMockAgent.initializeIfNeeded();}

  @Rule
  public PowerMockRule rule = new PowerMockRule();

  @Test
  public void test() {
    PowerMockito.mockStatic(System.class);
    Mockito.when(System.currentTimeMillis()).thenReturn((long)123);
    System.out.println(System.currentTimeMillis());
  }
}

最初，我尝试使用@RunWith(PowerMockRunner.class)运行此类。当跑步者尝试加载我的测试课程时，这会带来问题。 PowerMock文档建议bootstrapping using a Java agent有关类加载问题。

如果我使用Eclipse工具执行测试，JUnit将成功运行测试。这是我得到的故障跟踪：
