Cross browser testing tools are game-changers in the website and app development industry. In the past, developers and QA experts tested their websites manually. This was not only time-consuming but expensive.

With time, developers came up with automated testing tools that simplified the website testing process. This, with other improvements like the release of the best coding browser extensions, has made working with browsers enticing for developers.

However, choosing the right testing tool might be difficult due to the number of products out there. To ease your search, we have picked five of the best cross browser testing tools for you.

What is cross browser testing?

Cross browser testing is a nonfunctional test that ensures websites and web apps work as planned on different browsers across various devices.

The goal is to ensure end-users get the intended performance level irrespective of browser or device. Some of the tested parameters are speed, style, and other UI elements.

How is cross browser testing handled?

Cross browser testing could either be done manually or automatically. The choice depends on the complexity of the task and preferences.

Below is a quick rundown on the two methods:

1. Manual cross browser testing

In manual testing, you need to install the browsers you want to use for the test and their various versions. This will be done for different operating systems on desktop and mobile.

Also, you will write out the test cases for testing. This will be run on each browser on various devices, with debugging done manually.

Manual testing is effective for small projects. However, it can be time-consuming, and stressful when dealing with medium to complex websites.

2. Automated cross browser testing

Automated testing is done with online testing tools. These tools have been built to carry out all the difficult tasks. You only need to enter your website name or URL, the test cases, the browsers, and the operating systems to test.

More importantly, some of these automated tools provide the option of manual testing. This allows you to write custom codes to test your websites and pages to your satisfaction.

When can I perform cross browser testing?

The time to perform cross browser testing depends on your preference. Generally, there are three stages for testing:

  • At the start of website development: This involves testing a website or web app immediately after a page is developed. This test will be repeated for every page till the project is complete. While this can be time-consuming and tiring, it helps to detect errors at early stages.
  • After development: This is the process of testing the functionality of the app or web page after the development is complete. This allows you to fix the errors at once before releasing it to the end-users. This method does not usually take much time, but it might be problematic if you run into complex problems.
  • After the release of the website: In this case, you release the website to end-users before testing. This can be costly, as it might require multiple deployments based on the bugs fixed.

With the rate at which websites are developed, cross browser tools are now more important than ever. The best of them gives you so many options and delivers accurate results.
