【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。

 

复制代码
#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
复制代码

 

 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:
