Question

我是OCMock的初学者，我需要验证是否从另一个类调用了一个方法。以下是我的代码。

 //Creating the OCMockObject
id mockProductRequest = [OCMockObject mockForClass:[ProductRequest class]];
[[mockProductRequest expect] testProductRequest];

//Creating the object where the mock object will be invoked
ProductService *actualService = [[ProductService alloc] init];
[actualService testProductService];

[mockProductRequest verify];

-(void)testProductService{
//Method where the mock object's method is invoked
ProductRequest *request = [[ProductRequest alloc] init];
[request testProductRequest];
}

我好像总是收到一个没有调用异常的方法。请帮我弄清楚我在这里做错了什么。

您必须替换真实ProductService内的实际请求。例如，您可以通过使请求成为ProductService的属性来实现此目的：

@interface ProductService
@property (strong) ProductRequest *request

然后将真实的ProductRequest与像这样的模拟者交换

- (void)testProductService {
  id mockProductRequest = [OCMockObject mockForClass:[ProductRequest class]]; 
  [[mockProductRequest expect] testProductRequest];

  ProductService *actualService = [[ProductService alloc] init]; 
  actualService.request = mockProductReqeust;

  // call some method on actualService which invokes the request

  [request testProductRequest];


}

Mock Objects的目标是替换您想要测试的对象。但是在你的代码中，你将消息testProductRequest发送到一个真正的ProductRequest而不是你的MockObject！

使用OCMock验证是否调用了方法
