WebdriverIO – Cross Browser Testing

Table of Content

Cross-browser testing is essential to ensure your website is functional on all popular browsers and this can be easily achieved using WebdriverIO. Let’s take a look at how we can run our tests on Chrome and Firefox.

If you have set up your tests using WebdriverIO test runner then wdio-chromedriver-service will already be set up for you which will allow you to run tests on Chrome. If you have not set this up before, then you can watch the installation video to learn how to do this.

In addition, to run tests on Firefox you will need to install and configure geckodriver with your tests.

  • You can get the latest version downloaded from the link here.
  • Once downloaded, extract the file and store it in your tests root directory.
  • Update capabilities in the wdio.conf.js file –
  capabilities: [
      browserName: 'chrome',
      browserName: 'firefox',
  • Start geckodriver, you can do that by running the executable file that you downloaded ./geckodriver.exe
  • Now, run your tests npx wdio wdio.conf.js

That’s all you need to run tests in both chrome and firefox. ?

Note: If you get binary location error when running your tests –

Expected browser binary location, but unable to find binary in the default location

Then, you will also have to provide the path of where the firefox is installed in your machine when you run geckodriver by passing the --binary flag. Ex: ./geckodriver.exe --binary 'C:/Program Files/Mozilla Firefox/firefox.exe'

Check out this video to see a detailed explanation on how to run your tests 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.
