java.lang.IllegalStateException: incompatible return value type
提问by Dinesh
I am using EasyMock to create mock classes in test cases.
我正在使用 EasyMock 在测试用例中创建模拟类。
expect(entity.getType()).andReturn("string");
Type belongs to the Stringdatatype. In my development environment it is working fine. But If I transfer to my server and take build, it is failing with following error:
类型属于String数据类型。在我的开发环境中，它运行良好。但是如果我转移到我的服务器并进行构建，它会失败并出现以下错误：
java.lang.IllegalStateException: incompatible return value type
I don't know why it is failing in server and getting executed in my development machine.
我不知道为什么它在服务器上失败并在我的开发机器上执行。

I just had the same problem.
我只是遇到了同样的问题。
I had a partial mock in EasyMock, but forgot to call addMockedMethodfor the method I wanted to set the expectation for.
我在 中进行了部分模拟EasyMock，但忘记调用addMockedMethod我想要为其设置期望的方法。
The error message was the same as above, I'd say that was somewhat misleading.
错误消息与上面相同，我认为这有点误导。

In my case the method was finalon which I called expecton. So EasyMockwas not able to mock the method and thus did not record the method invocation.
就我而言，该方法是final我调用的方法expect。所以EasyMock无法模拟方法，因此没有记录方法调用。

Make sure that your entityobject is not a simple POJO (eg. new Entity()), and it was created with the createMock()methods of EasyMock.
确保您的entity对象不是简单的 POJO（例如new Entity()），并且它是使用createMock()EasyMock的方法创建的。

For me, I had to remember to call reset(...) on it after having used it once, or I (bizarrely) got this error message calling expect on it a second time.
对我来说，我必须记得在使用它一次后调用 reset(...) ，或者我（奇怪地）第二次收到这个错误消息调用 expect 。
