使用KIF进行iOS自动化测试的开发

原理：

基于ID来识别视图元素，然后私有API模仿用户的交互操作（使用代码触发点击、滑动、输入等），从而实现UI的测试。官方推荐的ID设置是基于accessibilityLabel，它是用于TouchOver（旁白）盲人辅助功能的可本地化的视图ID，给一个视图设置ID，TouchOver就能读出该ID，从而帮助盲人识别视图。从另一个角度讲，这个ID一定程度是用户可见的。（一般搭配 accessibilityHint 、accessibilityTraits使用）实践中比较方便的ID设置是基于accessibilityIdentifier，专门用来标识UI元素的ID，用户不可见。

使用:

添加测试TARGETS:

cocoapods引入KIF框架

target 'GeelyTravelTests' do
  pod 'KIF', :configurations => ['Debug']
  pod 'KIF/IdentifierTests', :configurations => ['Debug']
end

target 'GeelyTravelUITests' do
  pod 'KIF', :configurations => ['Debug']
end

API KIFUITestActor及其扩展类KIFUITestActor+IdentifierTests

等待视图出现（获取视图）、点击视图、滑动、拖动、输入、清空输入、设置进度条等

- (UIView *)waitForViewWithAccessibilityIdentifier:(NSString *)accessibilityIdentifier;
- (void)tapViewWithAccessibilityIdentifier:(NSString *)accessibilityIdentifier;
- (void)tapRowAtIndexPath:(NSIndexPath *)indexPath inTableView:(UITableView *)tableView;
- (void)tapItemAtIndexPath:(NSIndexPath *)indexPath inCollectionViewWithAccessibilityIdentifier:(NSString *)identifier;

#import <XCTest/XCTest.h>

@interface GTLoginTests : KIFTestCase

@implementation GTLoginTests

- (void)beforeAll {
    // 所有测试用例执行前
}

- (void)beforeEach {
    // 每个测试用例执行前
}

- (void)afterAll {
    // 所有测试用例执行后
}

- (void)afterEach {
    // 每个测试用例执行后
}

- (void)testLoginAccountExample {
    // TODO:切换环境
    
    // 登录
    if ([tester tryFindingViewWithAccessibilityLabel:@"Login account enter" error:nil]) {
        [tester clearTextFromAndThenEnterText:@"18268731130" intoViewWithAccessibilityLabel:@"Login account enter"];

        [tester tapViewWithAccessibilityLabel:@"登录"];
        [[tester usingTimeout:15] waitForViewWithAccessibilityLabel:@"机票"];
        NSLog(@"test--测试环境 登录成功");
    } else {
