检查参数值传递给函数在单元测试

Question

我使用OCMock v3做单元测试，我想测试下面的一段代码：

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

在我下面的测试情况下，我创建了一个student实例名称为“约翰”，23岁，然后我在试运行功能：

-(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 ? 

} 

在我的测试情况下，我想验证确切的参数值传递到功能checkIdentityWithName:age:。这就是名字“约翰”，并使用了23岁。如何验证在OCMock v3？ （有它的文档怎么做，在没有明显的例子。）

Answer 1

你可以把它像

-(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); 
    } 

希望这有助于
