检查在单元测试中传递给函数的参数值 [英] Check argument value passed into function in unit test

问题描述

我正在使用 OCMock v3 做单元测试，我想测试下面这段代码:

I am using OCMock v3 do unit testing, I want to test the following piece of code:

@implementation School
-(void) handleStudent:(Student*) student{
 Bool result = [self checkIdentityWithName:student.name age:student.age];
 ...
}
...
@end

在我的以下测试用例中，我创建了一个名为John"的 student 实例，年龄为 23.然后我运行测试中的函数:

In my following test case I created a student instance with name "John", age 23. and then I run the function under test:

-(void) testHandleStudent{
  Student *student = [Student initWithName:@"John" age:23];
  // function under test
  [schoolPartialMock handleStudent:student];

  // I want to not only verify checkIdentityWithName:age: get called, 
  // but also check the exact argument is passed in. that's John 23 in this case
  // how to check argument ? 

}

在我的测试用例中，我想验证 确切参数值 是否已传递到函数 checkIdentityWithName:age: 中.使用的是名字John"和年龄 23.如何在 OCMock v3 中验证?(在它的文档中没有明确的例子如何去做.)

In my test case, I want to verify that the exact arguments values are passed into function checkIdentityWithName:age: . that's name "John" and age 23 are used. How to verify that in OCMock v3? (There is no clear example in its documentation how to do it.)

推荐答案

你可以这样做

-(void) testHandleStudent{
    id studentMock = OCMClassMock([Student class]);
    OCMStub([studentMock name]).andReturn(@"John");
    OCMStub([studentMock age]).andReturn(23);

    [schoolPartialMock handleStudent:studentMock];
    OCMVerify([schoolPartialMock checkIdentityWithName:@"John" age:23]);
}

或

-(void) testHandleStudent{
        id studentMock = OCMClassMock([Student class]);
        OCMStub([studentMock name]).andReturn(@"John");
        OCMStub([studentMock age]).andReturn(23);

        OCMExpect([schoolPartialMock checkIdentityWithName:@"John" age:23]);

        [schoolPartialMock handleStudent:studentMock];

        OCMVerifyAll(schoolPartialMock);
    }
