OC 单元测试

TDD

一条testCase就是一个记录,就是一条测试用例

为了创造测试条件OCMock创造测试条件

测试顺序

//类方法 1
+(void)setUp {
    [super setUp];
}
// 6
+(void)tearDown {
    [super tearDown];
}
//对象方法 2 4.5
- (void)setUp {
    [super setUp];
    //不断重置信息
    
    // Put setup code here. This method is called before the invocation of each test method in the class.
}
// 4 5.5
- (void)tearDown {
    [super tearDown];
    //不断重置信息
    
    // Put teardown code here. This method is called after the invocation of each test method in the class.
}
// 3
- (void)testAdd {
    // This is an example of a functional test case.
    // Use XCTAssert and related functions to verify your tests produce the correct results.    
}
// 5
- (void)testPerformanceExample {
    // This is an example of a performance test case.
    [self measureBlock:^{
        // Put the code you want to measure the time of here.
    }];
}

    Person *p = [Person new];

    int a = 1;
    int b = 2;
    int c;
    c = [vc add:a with:b];
    NSString *someInfoString = [vc showSomeBodyInfos:p];
    // 判断逻辑测试
    XCTAssertEqual(c, 3);
