【读书笔记】iOS-OCUnit-单元测试

一，新建立一个hello工程---》在左侧会看到helloTests---->helloTests.m.如下图所示。

二，打开查看会看到如下代码。

#import <UIKit/UIKit.h>
#import <XCTest/XCTest.h>

@interface helloTests : XCTestCase

@end

@implementation helloTests

- (void)setUp {
    [super setUp];
    // Put setup code here. This method is called before the invocation of each test method in the class.
}

- (void)tearDown {
    // Put teardown code here. This method is called after the invocation of each test method in the class.
    [super tearDown];
}

- (void)testExample {
    // This is an example of a functional test case.
    XCTAssert(YES, @"Pass");
}

- (void)testPerformanceExample {
    // This is an example of a performance test case.
    [self measureBlock:^{
        // Put the code you want to measure the time of here.
    }];
}

@end

三，里面函数的说明。

1. -(void)setUp: 每个test方法执行前调用，用于类的创建，一些变量的初始化等

2. -(void)tearDown:每个test方法执行后调用

3. -(void)testXXX:这个是真正运行的测试方法，命名就是不带参数，以test开始。

四，Product-->Test--》运行测试。输出结果如下图所示：
