Question

我正在使用Jasmine和WebdriverIO学习UI测试。我将其与NodeJS一起使用。我有下一个测试代码：

const projectsPage = require('../../lib/pages/projects.page');
const by = require('selenium-webdriver').By;

describe('Projects page', () => {
  it('Search google', async() => {
    await projectsPage.navigateTo();
    driver.getTitle().then(function(title) {
      expect(title).toBe('Google');
    });
    driver.findElement(by.name('q')).sendKeys('test');
  })
});

运行它时，我收到错误消息：

Unhandled promise rejection: NoSuchSessionError: invalid session id
      (Driver info: chromedriver=2.46.628411 (3324f4c8be9ff2f70a05a30ebc72ffb013e1a71e),platform=Mac OS X 10.14.5 x86_64)

但是下面的代码执行成功：

describe('Projects page', () => {
  it('Search google', async() => {
    await projectsPage.navigateTo();
    driver.getTitle().then(function(title) {
      expect(title).toBe('Google');
    });
    driver.findElement(by.name('q'))
  })
});

哪里错了？

Answer 1

由于findElement和sendKeys也返回了Promise，因此您还必须等待这些方法：

await driver.findElement(by.name('q')).then(element => element.sendKeys('test'));

Answer 2

您的测试在代码真正运行之前结束，您应该等待每个异步语句
