cucumber - 测试在并行运行时中断

问题描述

当我并行运行功能时（通过设置maxInstances为2in wdio.conf.js），它们每隔一次都会失败，但是当maxInstancesis时1，一切正常。似乎这两个测试在并行运行时会以某种方式使用彼此的会话。知道它可能是什么吗？

一件重要的事情。Webdriver.io无法进行断言（因为它们是在不同的会话上以某种方式进行的），因此对于失败的断言，堆栈跟踪非常简单。

wdio.conf.js

exports.config = {
  specs: [
    './features/*.feature'
  ],
  maxInstances: 2,
  services: ['selenium-standalone'],
  capabilities: [
    { browserName: 'chrome' }
  ],
  baseUrl: 'http://localhost:4000',
  framework: 'cucumber',
  reporters: ['spec'],
  cucumberOpts: {
    require: ['./features/steps.js'],
    strict: true
  }
};

登录功能

Feature: Login page
  Scenario: Click on the search link redirects the user
    Given the user is on the login route
    When the user clicks on the search link
    Then he sees the search route

搜索功能

Feature: Search page
  Scenario: Click on the login link redirects the user
    Given the user is on the search route
    When the user clicks on the login link
    Then he sees the login route

步骤.js

const { Given, When, Then, Before, After } = require('cucumber');
const { assert } = require('chai');

Given(/^the user is on the login route$/, () => browser.url('/login'));
When(/^the user clicks on the search link$/, () => browser.click('.search-link'));
Then(/^he sees the search route$/, () => assert.equal(browser.isExisting('.search-route'), true));

Given(/^the user is on the search route$/, () => browser.url('/search'));
When(/^the user clicks on the login link$/, () => browser.click('.login-link'));
Then(/^he sees the login route$/, () => assert.equal(browser.isExisting('.login-route'), true));

解决方案

这是因为我试图使用browser-sync. 当使用任何其他 Web 服务器提供目录时，一切正常。据我了解，这是因为browser-sync在打开多个浏览器时尝试同步 url。
