先前配置的ChromeDriver服务仍在使用Grunt运行/运行Webdriver测试

Question

嗨,我正在尝试为我的反应应用程序编写mocha测试,利用selenium-webdriver.

我有几个问题,但帮助其中任何一个都会有所帮助,所以我可以继续前进.

1. 首先,理想情况下,我想在不同的测试中共享相同的webdriver会话,因为我不关心它们运行的​​顺序.我只想加载网页一次,运行所有测试,然后关闭网页.这可能吗？我最初将我之前和之后的案例放在一个描述之外的不同文件中,它工作正常......但是我无法在任何测试文件中访问驱动程序的实例.

2. 如果无法共享同一个会话,那么当我尝试运行两个specFiles时,如何解决下面的错误...

这是错误:

$ grunt test-e2e
Running "mochatest:e2e" (mochatest) task
Running Mocha tests on files
/Users/userName/Desktop/myReactApp/tests/e2e/testSpecOne.js
/Users/userName/Desktop/myReactApp/tests/e2e/testSpecTwo.js

Error: The previously configured ChromeDriver service is still running. You must shut it down before you may adjust its configuration.
    at Error (native)
    at Object.setDefaultService (/Users/userName/Desktop/myReactApp/node_modules/selenium-webdriver/chrome.js:264:11)
    at Object.<anonymous> (/Users/userName/Desktop/myReactApp/tests/e2e/testSpecTwo.js:8:8)
    at Module._compile (module.js:556:32)
    at loader (/Users/userName/Desktop/myReactApp/node_modules/babel-register/lib/node.js:144:5)
    at Object.require.extensions.(anonymous function) [as .js] (/Users/userName/Desktop/myReactApp/node_modules/babel-register/lib/node.js:154:7)
    at Module.load (module.js:473:32)
    at tryModuleLoad (module.js:432:12)

典型的测试如下:

import assert from 'assert';
import test from 'selenium-webdriver/testing';
import webdriver, {By, until} from 'selenium-webdriver';
import chrome from 'selenium-webdriver/chrome';
import chromedriver from 'chromedriver';
import helpers from './helpers.js';

chrome.setDefaultService(new chrome.ServiceBuilder(chromedriver.path).build());


test.describe('Main page', () => {

  let driver = new webdriver
                    .Builder()
                    .withCapabilities(webdriver.Capabilities.chrome())
                    .build();

  test.before(() => {
      helpers.launchTheApp(driver, 'http://localhost:8000/myApp', 'elementOne', 10000);
  });

  test.after(() => {
    helpers.closeTheApp(driver);
  })

  test.it('Test some items appear', () => {

    helpers.checkIfElementIsPresent(driver, By.className, 'elementOne');
    helpers.checkIfElementIsPresent(driver, By.className, 'elementTwo');
    helpers.checkIfElementIsPresent(driver, By.className, 'elementThree');

   });
});

我正在使用grunt-mocha-test来运行这样配置的测试

e2e:{
    options: {
        timeout: 3000000,
        ignoreLeaks: true,
        ui: 'bdd',
        run: true,
        log: true,
        reporter: typeof process.env.FUSION_BUILD_GENERATED === 'undefined' ? 'spec' : 'xunit-file',
        grep: grunt.option('grep')
    },
    src: ['tests/e2e/**/**/*Spec.js']
}

一种可能的解决方案是在隔离环境中运行会话（例如在Docker容器中）。然而，尝试使用标准 Selenium 来实现这一点很复杂 - 您必须手动启动和停止容器或使用Ansible等基础设施自动化工具。这就是一个名为Selenoid的新的 Selenium 兼容工具发挥作用的地方。只需在测试中请求两个单独的会话，它们就会在 Docker 容器内并行运行。这给了你很大的灵活性。我的演讲：https://www.youtube.com/watch?v =TGjpc32my0Y
