Parallel Testing – Selenium Standalone Service | WebdriverIO

Table of Content

WebdriverIO supports parallel testing out of the box when you run your tests. For example: if you have 3 spec files and you run your tests, it’ll open up 3 separate chrome windows and each spec file will run on its own window. This reduces test run time significantly and allows you to get quicker test feedback.

You can also run tests in parallel when running tests on multiple browsers, this can be done easily using Selenium Standalone Service. The advantage of using this service is that you don’t need any other driver services as it has the support for the following drivers:

  • ChromeDriver
  • FirefoxDriver
  • IEDriver
  • Edge WebDriver

Installation

npm install @wdio/selenium-standalone-service --save-dev

Configuration

Make the following changes in wdio.conf.js

  // add selenium-standalone in services
  services: ['selenium-standalone'],

  // add the necessary browsers
  capabilities: [
    {
      browserName: 'chrome',
    },
    {
      browserName: 'firefox',
    },
    {
      browserName: 'internet explorer',
    },
  ],

That’s all you need to run your tests parallel in multiple browsers. ?

Understanding Equivalence Partitioning and Boundary Value Analysis in Software Testing

Software testing techniques help ensure software quality and reliability, by helping us select test cases intelligently from the collection of test cases, such that all test scenarios are covered.

Boundary Value Analysis and Equivalence Partitioning are two testing techniques that help testers select a subset of test cases that covers all important test scenarios, even under time and budget constraints. By testing all the equivalence classes and boundary values, testers can reduce the risk of releasing software with defects.
