IOS单元测试实践

单元测试主要是检测某个方法或者接口是否可以正常使用

一.环境搭建

略

二.测试工具

IOS自带的单元测试工具：IOS Unit Testing Bunde

IOS自带的UI测试工具：IOS UI Testing Bundle

三.测试实践功能

获取定位城市

四.被测试功能

//获取当前定位的城市

- (void)cityStr:(NSString*)cityStr privenceStr:(NSString*)privenceStr;

{

WS(bself);

//城市

self.cityStr=cityStr;

//省份

self.privenceStr=privenceStr;

.若定位城市 为空取值判断.....

.........................

}

五.单元测试方法

导入单元测试与被测试方法相关包

#import<XCTest/XCTest.h>

#import"XXController.h"

//测试的接口方法要继承XCTestCase

@interfaceXXXControllerTest : XCTestCase{

@private XXXController* userHomeVC;

@private XXXView *homeBtnV;

}

@end

@implementationXXXControllerTest

//setUp为初始，测试执行前调用

- (void)setUp {

[supersetUp];

userHomeVC=[[XXXController alloc]init];

homeBtnV=[[XXX alloc]init];

// Put

setup code here. This method is called before the invocation of each test method

in the class.

}

//tearDown为结束，测试执行后调用

- (void)tearDown {

// Put

teardown code here. This method is called after the invocation of each test

method in the class.

[supertearDown];

}

//测试方法命名必须以test开头

-(void)testGetCity{

*userHomeVC=[[XXXController alloc]init];

//预期结果赋值

NSString*equalCity=@"安庆";

NSString*equalPrivence=@"安徽";

//调用被测试方法传参

[userHomeVCcityStr:@"安庆"privenceStr:@"安徽"];

//将获取倒的省份赋值给privenceStr

NSString*privenceStr=userHomeVC.privenceStr;

//将获取倒的省份赋值给city

NSString*city=userHomeVC.cityStr;

//输出日志

NSLog(@"省=%@城市=%@equalCity=%@",privenceStr,city,equalCity);

//断言获取倒的省份是否等于预期的省份，如果正确就返回true,否侧反回else

XCTAssertEqualObjects(city, equalCity,@"获取城市验证成功");

//断言获取倒的省份是否等于预期的城市 如果正确就返回true,否侧反回else

XCTAssertEqualObjects(privenceStr, equalPrivence,@"获取省验证成功");

}

六.测试结果

   执行成功
  执行失败
