Cross browser testing is the process of testing your website so that it renders perfectly on various browsers, operating systems, devices, and view ports. It is a crucial step in releasing software and applications that meet the needs and expectations of your users, irrespective of the browser being used by them. You need to ensure cross browser compatibility of your websites when accessed through:

See All Supported FrameworksHave you ever thought about what might happen if a user visits your website and discovers that your website is not rendering correctly? Instead, the user would prefer to switch to another website. According to a report by Zendesk, 50% of the customers will switch to a new product if they come across a bad product experience. It means that without rigorous testing, you potentially lose customers as well as their respective conversions.
Any website consists of different components like HTML, CSS, and JavaScript etc., and handling of these components varies significantly from one browser to another. Maintaining uniformity across platforms helps in building an improved end-user experience.
Before rolling out your website, you have to ensure that the site renders correctly on different browsers, browser versions , devices, and operating systems. Cross-browser testing helps achieve enhanced user-experience by identifying cross-browser compatibility errors of your websites and web apps. This helps in debugging the issues at a faster pace. It also helps to ensure that you don't compromise on the end-user experience.
Cross-browser testing should be performed during the development process, ideally after significant changes or updates to ensure compatibility across different browsers. Majoraly it can be divided into two phases:
During Development Phases: Conduct cross-browser testing at various stages of development, such as after implementing new features or updates, to catch compatibility issues early.
Before Deployment: Prior to deploying any changes or updates to production, perform comprehensive cross-browser testing to ensure consistent functionality and appearance across different browsers and devices.
In general, anyone who develops or designs the web application can test the app. However, the approach can vary from one organization to another. The software testing team or the development team is primarily responsible for performing cross-browser testing. Research analysts and digital marketing experts often play a crucial role by gathering data for usage and traffic for jotting down the most prominent browsers and devices.
The QA team performs cross browser testing to determine the end-user experience. The same test scenarios are tested across multiple platforms and browser combinations to ensure uniformity of functionality. On the other hand, the development team tests the layout and UI features like-images, fonts, alignments, etc., on multiple browsers and make the necessary code changes.
Cross-browser compatibility issues happen because each web browser has its own engine, responsible for showing website content. When you visit a web address, the browser engine interprets the website's programming (like HTML, CSS, and JavaScript) to display it. Since each browser interprets code differently, it can lead to compatibility problems. Cross-browser testing helps catch and fix these issues before they affect users.
Cross-browser compatibility issues stem from variations in how each browser renders content. To deliver an exceptional user experience, you need to carefully specify HTML, CSS, and JavaScript properties. However, some CSS properties may not work well across different browser engines. Cross-browser testing is crucial as it resolves these compatibility issues, ensuring seamless performance for your website and web applications across various browsers.
With the plethora of browsers, devices, and operating systems out there, it is challenging to cover all the major browser and OS versions. It is recommended to limit the research effort to optimize your website's scope within your target audience. You need to analyze the most significant browsers and versions on the following basis:
Based on the above research, select the major browser and OS combinations having high user-traffic. Generally, marketing and Data research plays an essential role in jotting down the most popular browser and operating system, which then helps product and testing teams ease their functional area efforts.
Below are the strategies for making cross browser tests easier and faster:
For test scenarios, prioritize critical ones first, considering factors like time, risk, and required tools. Test essential features across major browser-OS combinations. If bugs are found, communicate test case results to the development team promptly for resolution.

Once you have selected the popular browser-OS combinations, you can initiate your testing process.
When you have a plethora of devices and browsers available, you need to devise an effective cross-browser testing strategy to perform cross browser compatibility on platforms that matter to you. You need to formalize a browser compatibility matrix based on the target audience, geo-location, and usability trends. A Browser Matrix is a structured list of browsers that ensures that you cover all relevant browsers and reduce the effort involved in development and testing.
To build a browser compatibility matrix, You have to get vital data points comprising platform, desktop browser usage, and mobile browser usage.
On completion, you can build a list of browsers and perform testing on the same.
In order to ensure smooth functioning and compatibility across various browsers, browser testing usually examine a number of important aspects. Among these characteristics are:
There are two approaches:
Manual Cross Browser Testing
Manual Cross Browser testing is also known as live interactive testing, and it is the conventional method used for cross browser testing. Earlier, when the need for cross browser testing arose, people had only one choice: Install each browser in their system. That was when the count of browsers was few and the need for cross browser testing minimal, but now with an increase in browser number, it has become crucial.
In manual testing, browsers have to be installed on different machines against which cross browser testing is performed.This method is time-consuming and takes a lot of effort.
Automated Cross Browser Testing
Manual cross browser testing is not feasible with multiple browsers, OS, and devices on the market today. It is technically challenging to cover such a large combination manually. Therefore, automated cross browser testing is vital for all organizations who want their application to run seamlessly across platform and device combinations. Post that, automation testing tools come into the frame.
Automation tools let you perform automated browser testing in no time. It has been made possible by the cross browser testing tools available today in the market like LambdaTest. These tools allow you to test your website across 3000+ browsers and browser versions without actually installing them.
Cross-browser testing may seem like a smooth process at first glance, but it comes with its fair share of challenges. Let's delve into some common issues faced by developers and testers during cross-browser testing and their solutions:
Cross-browser testing is essential to ensure that your web application or website functions correctly across different web browsers and their various versions. Here's a checklist to help you ensure thorough cross-browser testing:
