使用SpringRunner和PowermockRunner的异常

Question

我正在尝试测试JavaMail api并使用SpringRunner和PowerMockRunner,但它失败了.

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringRunner.class)
@PowerMockIgnore(value = {"javax.management.*"})
@SpringBootTest
public class BaseITest {

  @PrepareForTest(value = {MyStaticHelper.class})
  @Test
  public void testListFolders() {
     // mock static method
     // Use JavaMail API
  }
}

我得到这个例外:

javax.mail.MessagingException: java.security.NoSuchAlgorithmException: class configured for SSLContext: sun.security.ssl.SSLContextImpl$DefaultSSLContext not a SSLContext

如果我删除@PowerMockIgnore(value = {"javax.management.*"}),那么我收到此异常:

Caused by: java.lang.LinkageError: loader constraint violation: loader (instance of org/powermock/core/classloader/MockClassLoader) previously initiated loading for a different type with name "javax/management/MBeanServer"

使用的依赖版本是:

• powermock-api-mockito:1.7.1
• powermock-module-junit4:1.7.1
• mockito-all:2.0.2-beta
• mockito-core:2.8.9

有人可以帮忙吗？

它看起来像一个错误。

对我的案例有帮助的解决方案是缩小加载的配置范围。

尝试指定要加载的最小配置集：

@SpringBootTest(classes = SomeSpesificConfiguration.class)
