Getting Started With Browser Testing on LambdaTest

With different options available for web browsers, operating systems, and devices, it is imperative for developers to offer a consistent user experience. Web developers and testers work closely to run test scripts (manually and automatically) on various browsers.

Because different web browsers use different rendering engines, the same website may function differently on each. This underlines the importance of browser testing to ensure an easy, convenient, hassle-free online experience.

What is browser testing?

Browser testing refers to the process of testing a website/ web app across different combinations of browsers, operating systems, and versions. Hence, a website should be compatible with all browsers like Chrome, Firefox, and Safari and across all operating systems like Windows, Mac, Android, etc.

How to Perform browser testing?

The aim of browser testing is to detect and resolve the errors before real users encounter them. There are two methods to execute browser testing:

  1. Manual browser testing: The process of manually running test scripts to identify issues in web application’s functionalities. Due to the difficulty of testing a site across so many browsers, this process can be time-consuming and costly. Hence, it is best suited for simple websites and applications.
  2. Cross Browser Automated Testing: Organizations that want to meet their needs for scalability can choose automated browser testing. A browser testing tool allows a tester to find errors in the front end of a web application on a specific web browser.

Challenges in browser testing

There are many different web browsers that are widely used by people, including Chrome, Safari, Firefox, and Internet Explorer. Every browser has more than 10 versions running on a variety of operating systems, such as Windows, Mac, Android, etc.

Each browser uses a different rendering engine to render web technologies like HTML, CSS, and JavaScript, such as Chrome running on Blink, Firefox on Gecko, and IE on EdgeHTML and Chakra. Therefore, the same website behaves differently on multiple browsers. In that case, you need cross-browser testing to check how your website performs across all major browsers, browser versions, operating systems, and mobile devices.

However, the main challenge in browser testing is getting access to all the browsers and versions that people use nowadays. Let’s take a look at the recent stats on how much market share each browser occupies.

  • Chrome- 63.56%
  • Safari- 19.85%
  • Edge- 5.43%
  • Firefox- 2.94%
  • Opera- 2.74%
  • Samsung Internet- 2.33%

Furthermore, there are various other browsers that people use to view your website. Combining each browser with different versions makes this process even more challenging. If you fail to provide a smooth performance of your website on any of these browsers, you will be losing customers, conversion opportunities, and money. Therefore, it is important to select the right browsers and versions according to your target audiences, requirements, and features.

Moreover, setting up device labs, emulators/simulators, or manually accessing browsers for browser testing can be a time-consuming and costly process. Also, these browsers are updated frequently, making it difficult to keep the track of latest, running, or outdated browser versions.

Therefore, LambdaTest AI-powered test orchestration and execution platform, is the perfect solution to test your websites and web applications on more than 3000 browsers, browser versions, mobile devices, and OS combinations. With LambdaTest, you can run multiple test cases parallelly and execute in less time compared to other methods. Consequently, this is a preferred testing tool to meet the cross browser needs of many businesses, including start-ups, freelancers, etc.

Preparing for browser testing

A non-responsive website with an inadequate UI layout can leave your user frustrated, impacting your services and business. Hence, browser testing is essential to ensure a full-fledged, user-friendly website. Nowadays, QA testers and web developers have made responsive and browser testing a crucial part of website development.

With the right strategy and tools, you will able to execute testing much faster and obtain better results. Here are some of the strategies you can follow to ensure impactful and convenient browser testing with reduced downtime.

  1. Carefully choose the right combination of browsers, browser versions, and operating systems as per your testing requirements and target audiences. Focus on the browsers that are widely used by people so you can provide a better user experience on them.
  2. Set the testing environment after analyzing the risks, defining tools, identifying goals, etc. You can assign bugs to the development team to resolve according to their priority.
  3. Choose browser add-ons and emulators/simulators to run test cases and find compatibility issues on various browsers and devices.
  4. Reduce the testing time and workload with automation and parallel testing that enable you to execute test cases on multiple environments.
  5. Prioritize testing website responsiveness on mobile devices as most people access a website on them.
  6. Save your time and cost with a cloud-based testing platform.
