Cross Browser Testing


The internet’s popularity is one that is difficult to exaggerate. It has penetrated every segment of society and is now a staple of daily lives for billions of people around the world. This inarguable fact means that web developers and designers must always be on their toes to ensure that the websites they develop are enjoyable and functional across a plethora of devices, platforms, and viewports. This requires a well-organized cross browser testing strategy to deliver a robust and competitive product to the market.

Cross browser testing is a process of testing a website or web-app across numerous browsers, browser versions running on different operating systems to ensure rendering of the website stays as intended. The primary reason for performing cross browser testing lies with the differences between rendering engines of different browsers.

We often forget or get confused between the literal meaning of responsive testing and cross browser testing. Cross browser testing deals with functionality and interoperability, while responsive web testing focuses on aesthetics and adaptability. Both are crucial in website development but are quite distinct from each other.

To get started with Cross Browser Testing, let’s understand the difference between Responsive Testing and Cross Browser Testing

Strategizing Cross Browser Testing

Cross browser testing is not as simple as it sounds. It is in itself a whole different ecosystem and requires a lot of planning and prerequisites before you decide to go ahead with that. You must understand cross browser testing processes focusing on efficient strategies, which can cut down on the time and effort required for high-impact testing.

Let us dig deep into the Cross Browser Testing Strategy in three easy yet crucial steps.

Setting Up The Perfect Testing Environment

You may be in denial about testing a website across thousands of browsers in 10 days or less. Because even if everything is provided on the cloud, executing cross browser testing manually will take a lot of time.

This blog demonstrates setting up a perfect Cross Browser Testing Environment.

Design A Checklist Before You Go Live

Formulating a perfect cross browser testing strategy might help in browsing the website on different browsers and platforms. However, you need to be prepared for some un-welcomed bugs. A proper checklist might help you avoid them or figure them out before anyone else does.

Go through this Cross Browser Testing Checklist, and you’re all set to go live.

A browser interprets web elements in a different manner as compared to other browsers and renders the website accordingly. This means the look and feel of a website are not only dependent on the front-end development team but also on the browsers being used to access the website.

Which Browsers Are Important For You?

The number of browsers used by your customers may vary from hundreds to thousands, depending upon which browser version they are using, which device they are using it from? Are you getting the majority of traffic from mobile browsers or desktop ones? Are you targeting the right browser with respect to the geographic locations of your targeted audience?

This blog will help you figure out the Perfect Browser List to strategize cross browser testing.

Testing On Older Browser Versions

It can be an overwhelming task to ensure a cross browser compatible website that works seamlessly even on older browsers. New browser versions are released every month, which makes it difficult for testers & developers to maintain a record of emerging & deprecated features.


You should check out the different ways to perform cross browser testing on Old Browser Versions.

With so many options available in the market, the user always remains in a dilemma about which tool to use. We are here to ease your problem and help you use tools like LambdaTest to perform cross browser testing.

Manual Cross Browser Testing

The various types of cross browser testing that you can perform using LambdaTest includes:

  • Real-time live interactive testing on mobile and desktop devices.
  • Visual UI testing to find out regression bugs using screenshot testing, responsive testing, and smart testing.

Find out more about performing manual cross browser testing in its various forms.

Automated Cross Browser Testing

Using cloud-based tools for automated cross browser testing such as LambdaTest can help you get rid of the hectic installation and setup process for maintaining your in-house Selenium Grid. Find all the details of how web development has been changing in the past few years and how it has led to browser compatibility issues.

Learn all about how Automated Cross Browser Testing is shaping up for modern web development.

As it is nearly impossible to achieve 100% test coverage (unless and until your product has very simple requirements & implementation), the test team should come up with test cases/test suites that can help in testing the core functionalities of the product, thereby achieving the best coverage results.

Let's look into how to leverage a Pairwise Testing algorithm for performing cross browser testing.

Cross browser testing is considered a vital part of every front-end website testing plan to have a seamless UI & UX for the audience. A master front-end testing plan should incorporate precautions required to reduce time, effort, and money.

Testing A Web App

Instead of trying to make the web app compatible with all browsers, it is wiser to choose the major browsers first and then cover other browsers. According to W3C, 97% percent of the internet traffic uses four major browsers, Chrome, Firefox, IE, and Safari.

Here is a detailed analysis of Testing A Web Application for cross browser compatibility.

Testing A PWA

A term that originated in 2015 from within the heart of Google, Progressive Web Apps (PWA), is a set of design principles. Modern browsers are capable of providing features that are usually utilized by native applications on various operating systems. The design principles that guide the developers to best use the provisional capabilities of the browser encompass the PWA.

Find out how Testing A PWA is much different from testing traditional web applications.

Testing A Front-End Website

For an authentic front-end testing plan for a website, functionality and performance have to be checked on different devices and browsers (with multiple versions). A master front-end testing plan should incorporate precautions required to reduce time, effort, and money.

Jump to this guide to know the why & how of creating a front-end testing plan.

Testing Websites Remotely

The COVID pandemic has hit all the industry as S&P 500 has dropped around 30% since it's all-time high in February. There’s an estimated 10-25% decrease in revenue for SaaS companies. As in-house device farms and lofty infrastructure goes defunct, you can still solve your cross browser testing woes of how to test your websites on different browsers remotely.

Learn all about testing websites on different browsers remotely.

Testing Websites For Different Locations

Your website may look different to people belonging to different geolocations! So, is it important to perform geolocation testing? Absolutely! Geolocation testing is a practice where you perform website testing from a set of IPs that belong to different countries around the globe.

This blog discusses the reasons to perform Geolocation Testing and the ways in which you could do it, along with amazing tools.

With the customer’s attention span getting shorter with time, they won’t hesitate to press the back button on their browser if a site seems faulty. Even though the goal sounds simple, there are many obstacles the entire QA team has to sort through to increase the responsiveness of sites and web applications.

Saving Time On Manual Cross Browser Testing

The major pain-point with manual cross browser testing is that testers might need to spend a significant amount of time testing different web pages, cross browser testing web apps across different breakpoints on a growing list of ‘complex’ combinations.

Have a look at some of the mechanisms to improve Manual Cross Browser Testing.

Cross Browser Testing With Minimal Efforts

Cross browser testing should be an iterative process i.e., testing on the ‘shortlisted browsers, operating systems, devices, etc.’ should be performed before the changes are pushed to the production server. This process should be repeated before every new release.

This guide will help you Skyrocket Your Cross Browser Testing with minimal effort.
