jmockit类强制转换异常

我正在尝试模拟一些webogic类和接口来测试执行此操作的方法:

void init(oracle.wsm.policy.model.IAssertion assertion,....) {
...    
oracle.wsm.policy.model.IAssertionBindings bindings = ((oracle.wsm.policy.model.impl.SimpleAssertion) assertion).getBindings();
...
}

我的测试代码如下:

  @Test
  public final void testInit() {


  IAssertion assertionMock = new MockUp<IAssertion>() {
      @Mock
      QName getQName() {
        return new QName("qname");
      }
   }.getMockInstance();


   CustomAuditPolicy custom = new CustomAuditPolicy();
   custom.init(assertionMock);

我得到了:

java.lang.ClassCastException: $Impl_IAssertion cannot be cast to oracle.wsm.policy.model.impl.SimpleAssertion
    at xxx.CustomAuditPolicy.init(CustomAuditPolicy.java:82)
    at xxx.CustomAuditPolicyTest.testGetAssertionName(CustomAuditPolicyTest.java:190)

SimpleAssertion类实现了IAssertion,所以我一直在尝试模拟SimpleAssertion类,但仍然遇到同样的错误。

有人可以解释一下如何在这种情况下使用jmockit吗?

答案 0 :(得分:1)

在这种情况下,您需要模拟SimpleAssertion实现类,因为这是测试中的方法所期望的。在界面上使用MockUp<IAssertion>只会获得一个不是SimpleAssertion的动态代理类,因此ClassCastException
