嘲讽不工作的插座

Question

类

我想回到每当新的Socket（“服务器IP”，端口编号）被称为定义Socket实例， 我的代码看起来像这样（我使用了EasyMock）

public static Socket mockSocket ; 
public static Object []arguments = {"Test Client",8443}; 
........................................... 
.............................................. 

mockSocket = new Socket("20.206.214.76", 8080); 

PowerMock.createMock(Socket.class, arguments);  

expectNew(Socket.class,arguments).andReturn(mockSocket); 

其给我的编译错误 - >

PowerMock.createMock(Socket.class, arguments); 

错误是：

"The type org.easymock.ConstructorArgs cannot be resolved. It is indirectly referenced from required .class files" 

有人可以请帮助？

您的类路径中没有必要的EasyMock罐。编译器正在寻找类org.easymock.ConstructorArgs并找不到它。

然而，一旦你在你的类路径中获得了正确的jar包，你就需要对Java和嘲笑有一个大致的了解。

// here you create a *real* Socket and assign it to 'mockSocket' 
mockSocket = new Socket("20.206.214.76", 8080); 

// here you create a mock Socket, but don't assign it to anything 
// 'arguments' probably doesn't do what you expect. 
PowerMock.createMock(Socket.class, arguments); 

// here you tell your test case to intercept calls to `new Socket()` and 
// return mockSocket (which, as we see above) is a real socket. 
expectNew(Socket.class,arguments).andReturn(mockSocket); 

你真正需要做的是不创建一个真正的插座。将您创建的模拟套接字分配给mockSocket，并将其用于expectNew。您的测试课程需要注明@PrepareForTest，否则expectNew()将不起作用。

@RunWith(PowerMockRunner.class) 
@PrepareForTest(MyClass.class) 
public class MyClassTest { 
    // ... 
    @Test 
    public void testSocket() { 
     // create mock object 
     Socket mockSocket = PowerMock.createMock(Socket.class); 
     // tell test runner to intercept 'new Socket()' 
     expectNew(Socket.class,arguments).andReturn(mockSocket); 

     MyClass objectUnderTest = new MyClass(); 
     // do things to objectUnderTest 
     // because of @PrepareForTest and expectNew(), when MyClass 
     // hits 'new Socket(...)' the mock will be returned instead. 
     // assert things about objectUnderTest 
    } 
}
