Angular 2 E2E测试入门 有大用 有大大用

    npm install -g angular-cli@latest

    npm install -g protractor

    ng serve

    protractor
    ng e2e
    yarn e2e

import { browser, element, by } from 'protractor'; //每个测试文件都要引入一个browswe全局变量

describe('Demo App', function () {
   beforeEach(() => {
    browser.get('/');  //导航到首页
  });
});

    it('should show thirteen items when we first load the demo app', () => {
    browser.get('/');
    const items = element.all(by.css('app-root ion-content button')); //选择多个元素
    const expectCount = 13;

    expect(items.count()).toBe(expectCount); // items.count()统计元素个数
  });

    it('should display message title demo-module', () => {
    browser.get('/');
    const title = element(by.css('app-root ion-title'));
    const titleText = title.getText(); //抓取元素文本

    expect(titleText).toEqual('demo-module');
  });

   it('should display fifthItem details message', () => {
    browser.get('/');
    const itemNumber = 4;
    const fifthItem = element.all(by.css('app-root ion-content button')).get(itemNumber);

    fifthItem.click(); //点击元素
    const outText = element(by.css('app-root sino-text-content')).getText();

    expect(outText).toContain('关于做好保密自查自评工作的通知');
  });

   it('should show message of login', () => {
    browser.get('/#/login'); //使用deepLink配置路径之后，可直接导航到对应页面
    const loginContent = element(by.css('sino-login'));
    const loginContentEl = loginContent.getText();

    expect(loginContentEl).toContain('登录页面');

    const userName = element(by.css('.userName')).sendKeys('王佳禾'); //传递对应参数的值

    const button = element(by.css('sino-login button'));

    button.click(); //点击事件

    const toast = element(by.css('.toast-message'));
    const toastEl = toast.getText();

    expect(browser.ExpectedConditions).toBe('登录成功!');
