1.创建测试工程

File-->New--->Target-->iOS Unit Testing Bundle

2.引用主工程

@testable import 主工程名

3.podfile中引入测试工程

 target 'YStarTests' do
        inherit! :search_paths
    end

4.项目配置文件调整

Enable Testability

5.单元测试编写

逻辑测试

//逻辑测试举例： 测试期望结果与实际结果是否相等
    func testAdd(){
        let expectValue = 20
        let actualValue = 30
        XCTAssertEqual(expectValue, actualValue)
    }

功能测试

  //功能测试：测试登录功能（异步测试）
    func testLogin() {
        let expectOption = expectation(description: "登录测试")
        let param = LoginRequestModel()
        param.phone = "18657195470"
        param.pwd = "123456".md5()
        AppAPIHelper.commen().login(model: param, complete: { (result) -> ()? in
            
            if let object = result as? StarUserModel{
                if let uid = object.userinfo?.id{
                    ShareModelHelper.instance().uid = Int(uid)
                    UserDefaults.standard.set(uid, forKey: AppConst.UserDefaultKey.uid.rawValue)
                }
                if let phone = object.userinfo?.phone{
                    ShareModelHelper.instance().phone = phone
                    UserDefaults.standard.set(phone, forKey: AppConst.UserDefaultKey.phone.rawValue)
                }
                ShareModelHelper.instance().token = object.token
                UserDefaults.standard.set(object.token, forKey: AppConst.UserDefaultKey.token.rawValue)
                expectOption.fulfill()
            }
            return nil
        }, error: nil)
        waitForExpectations(timeout: 15, handler: nil)
    }

性能测试

 //性能测试：测试登录功能和Add方法性能表现
    func testPerformanceExample() {
        // This is an example of a performance test case.
        self.measure {
            // Put the code you want to measure the time of here.
            self.testLogin()
            
            self.testAdd()
        }
    }
