在JMockit中模拟测试类的私有方法 [英] Mock a private method of the class under test in JMockit

问题描述

在我的测试类（CUT） - 一个ejb - 我有一个私有方法getConnection。
我想测试CUT的另一种方法，但这种方法会在手前失败。

In my class under test (CUT) - an ejb - I have a private method "getConnection". I want to test another method of the CUT but this method will fail before hand.

我尝试过如下所示，但调用是错误的。我不想调用该方法，我想将其存根。但是怎么样？ （'connection'是存根）

I tried it like shown below, but "invoke" is wrong. I don't want to invoke the method, I want to stub it. But how? ('connection' is a stub)

new NonStrictExpectations() {
  {
    invoke(archivingBean, "getConnection");result = connection;
  }
};
archivingBean.moveCreditBasic2Archive(new Date());

推荐答案

您的测试是正确的，但它缺少声明对于模拟类型。在这种情况下，EJB类。

Your test is correct, except that it's missing a declaration for the mocked type. The EJB class, in this case.

通常，模拟类型是完全模拟的（所有方法）。在这种情况下，您可以向测试方法声明一个 @Mocked MyEJB archivingBean 参数。例如。

Normally, mocked types are mocked in full (all methods). In such cases, you would declare a @Mocked MyEJB archivingBean parameter to the test method, for example.

For 部分模拟，另一方面，您使用 NonStrictExpectations（Object ...）构造函数，如下所示：

For partial mocking, on the other hand, you use the NonStrictExpectations(Object...) constructor, like this:

new NonStrictExpectations(archivingBean) {{ // <== note the argument here
    invoke(archivingBean, "getConnection"); result = connection;
}};
