Mockito异常-when()需要一个参数,该参数必须是模拟对象的方法调用
我有一个使用Mockito和Spring Test框架的非常简单的测试用例。当我做
when(pcUserService.read("1")).thenReturn(pcUser);
我得到这个例外。
org.mockito.exceptions.misusing.MissingMethodInvocationException: when() requires an argument which has to be 'a method call on a mock'.
For example:
when(mock.getArticles()).thenReturn(articles);
Also, this error might show up because:
1. you stub either of: final/private/equals()/hashCode() methods.
Those methods *cannot* be stubbed/verified.
2. inside when() you don't call method on mock but on some other object.

我尝试使用不同的方法,但继续收到此错误消息。我在Mockito中使用Spring 3.1.0.RELEASE。请分享并指导我正确的方向。
回答:
您需要先创建pcUserService的MOCK,然后使用该模拟。
PcUserService mock = org.mockito.Mockito.mock(PcUserService.class);when(mock.read("1")).thenReturn(pcUser);
