jMock Mocking Classes and Interface
提问by Roy Marco Aruta
I was experimenting jMock as my mocking framework for my project. I came into a situation where I need to mock both a class and an interface. I used the ClassImposteriser.INSTANCEto initiate the impostor of the context.
我正在试验 jMock 作为我项目的模拟框架。我遇到了一种情况，我需要同时模拟一个类和一个接口。我使用ClassImposteriser.INSTANCE来启动上下文的冒名顶替者。
Supposing a class Validatorand an interface Personto mock. When I was going to mock the Interface Person, I ran to a problem NoClassFoundDefError. When I mocked the class Validator, there was no problem.
假设一个类Validator和一个接口Person来模拟。当我准备模拟接口时Person，我遇到了一个问题NoClassFoundDefError。当我嘲笑班级时Validator，没有问题。
I need both that class and interface but I can't solve the problem. Please HELP.
我需要那个类和接口，但我无法解决问题。请帮忙。
Code Example:
代码示例：
Mockery
嘲弄
private Mockery context = new JUnit4Mockery() {{ setImposteriser(ClassImposteriser.Class) }};
private Mockery context = new JUnit4Mockery() {{ setImposteriser(ClassImposteriser.Class) }};
Class :
班级 ：
private Validator validator;
private Validator validator;
Interface :
界面 ：
private Person person;
private Person person;
Inside Test Method
内部测试方法
validator = context.Mock(Validator.class);----> Working
person = context.Mock(Person.class);---->NoClassFoundDefError
validator = context.Mock(Validator.class);----> 工作
person = context.Mock(Person.class);---->NoClassFoundDefError

The code as you present it won't compile (it should be ClassImposteriser.INSTANCE). The example code below seems to work fine. Perhaps you could provide some more details?
您提供的代码将无法编译（它应该是 ClassImposteriser.INSTANCE）。下面的示例代码似乎工作正常。也许您可以提供更多详细信息？
public class Example {
private Mockery context = new JUnit4Mockery() {
{
setImposteriser(ClassImposteriser.INSTANCE);
}
};
@Test
public void testStuff() {
Validator validator = context.mock(Validator.class);
Person person = context.mock(Person.class);
// do some stuff...
}
public static interface Person {
}
public static class Validator {
}
}
