The world is digitally diverse, and today, more than ever, the worry about your website working well across different browsers has risen to a higher level. Users come onto the web through all sorts of browsers, all carrying quirks and their unique rendering engine. Browser compatibility testing makes sure that whatever device or browser you are targeting provides consistent quality and experience.
The following ultimate checklist with step-by-step to test website on different browsers will help ensure that no important aspects are missed to deliver the perfect user experience.
Importance of Cross-Browser Testing
- Browser Compatibility
Compatibility with browsers basically means that your website should appear and function as desired on all varieties of web browsers. And each of these browsers interprets HTML, CSS, and JavaScript differently: Chrome, Firefox, Safari, Edge, and all the rest. And each of these differences might result in a different look and feel of your site. That’s why cross-browser testing is so vital; it helps you maintain consistency and usability.
- Impact on User Experience
A website that does not perform well in all browsers is the assurance of a bad user experience. It may seriously affect satisfaction, participation, and retention among users. They might be able to view broken layouts or an absence of certain features while facing functional problems, frustrating them enough to drive them away from your website.
- SEO Implication
Search engines like Google want websites that offer a fantastic user experience. A website that doesn’t work well across multiple browsers decreases the quality of their users’ experiences and thus harms your search engine rankings. Having cross-browser compatibility contributes to a good user experience and will help your SEO performance.
The Ultimate Checklist for Cross-Browser Testing
-
Define Your Testing Scope
1.1 Identify Target Browsers
Start by taking note of the most-used browsers within your audience. Look into your website analytics to see what browsers and browser versions your users use. You can then focus your testing on those browsers so you’ll resolve the most critical compatibility issues.
1.2 Identify Browser Versions
Consider testing the latest browser versions, as well as varieties that are still in use. This will widen the compatibility to include users who may not upgrade to the latest versions of browsers. Concentrate on those versions that have significant market share or are historically known to pose particular compatibility issues.
-
Prepare Your Test Environment
2.1 Create a Test Lab
Arrange for a testing environment with browsers and their versions. This may include setting up virtual machines, emulators of browsers, or using cloud-based services for testing. Ensure that your testing environment replicates as much of the diversity of devices and browsers used by your target audience.
2.2 Browser Testing Tools
Perform the testing by applying browser testing tools and platforms. Software tools like LambdaTest provide professional-level cross-browser testing to test your website in multiple browsers and devices in much less time than that required by manual methods. LambdaTest is an AI-powered test execution platform that allows you to perform website testing at scale over 3000+ environments. In addition, it also supports Cypress, Playwright, and Selenium testing.
These tools provide you with both real devices and automated testing capabilities to make the testing easier.
2.3 Testing: Manual vs. Automated
Find the balance of manual and automated testing. Concerning this, one should stress that manual testing involves individual browser testing to reveal some view and functional issues. Simultaneously, automated testing is supposed to work with the scripts running on different browsers multiple times. The combination can give comprehensive coverage and efficiency.
-
Testing Core Functionality
3.1 Check Layout and Design
Test if your website’s layout and design are identical on different browsers. Ensure that headers, footers, navigation menus, content areas, and other elements look as they should. Give particular attention to the spacing and alignment of elements, and pay attention to overall aesthetic perspective.
3.2 Test Forms and Interactive Elements
Test all forms and interactivities including all buttons, links, and input fields. These should function properly and respond appropriately to user manipulations. Test for broken links, form validation errors, and non-responsive buttons.
3.3 Testing Media and Graphics
Media display should be appropriately tested to ensure that images, videos, and animations appear correctly across different browsers. See whether images load fine and appear, videos can be played without any issues, and animations perform smoothly.
-
Performance and Speed Testing
4.1 Page Load Time Analysis
While performance shouldn’t be a problem, test for page load time within multiple browsers. Analysis and optimization can be done with Google PageSpeed Insights or GTmetrix. Slow loading pages will only serve to make user experience worse and further hurt search engine rankings.
4.2 Test Responsiveness
Check that your website is responsive and can handle all the various screen sizes and resolutions of different computers, devices, smartphones, and tables. Your website can scale down to various devices, and the content on the screen must remain readable, and the site’s navigation continues to work across the gradient of screen sizes.
4.3 Monitor Resource Loading
Verify that all resources successfully load into every browser. Note any loading issues, or resource incompatibilities that may cause a website’s functionality to fail.
-
HTML, CSS, and JavaScript Validation
5.1 HTML Validation
Validate your website’s HTML using web standards and best practice. Using resources like the W3C Markup Validation Service find and fix all HTML errors and warnings that could impact cross-browser compatibility.
5.2 CSS Validation
Test your CSS to ensure it is written correctly and is cross-browser compatible, using the W3C CSS Validator. The tool will find any errors or inconsistencies in your stylesheets, which you really should know about.
5.3 JavaScript Functionality
Test if the JavaScript is working, which should make the scripting of a web page work on most browsers. Verify that all interactive elements, dynamic content, and other custom functionalities are working as they should. Test for any browser-specific issues or bugs related to JavaScript.
-
Browser-Specific Feature Testing
6.1 Vendors Prefixes Handling
Some CSS properties may require vendor prefixes in various browsers. Your stylesheets should contain appropriate prefixes that will work on each browser. Software like Autoprefixer can automate adding vendor prefixes to your stylesheets.
6.2 Fix Browser-Specific Bugs
Find and eliminate browser-specific bugs or quirks. For example, some browsers have known bugs related to specific CSS properties or JavaScript methods. Apply browser-specific CSS rules or JavaScript hacks to deal with the bug.
6.3 Test Browser Extensions
You may wish to test your site with some popular browser extensions that a user might have installed on her browser. Some extensions will impact either how your site looks, or how it functions.
-
Usability Testing
7.1 User Feedback
Gather as much feedback as possible from actual users accessing your website using different browsers. Conduct a series of usability tests to find out problems or areas that need improvement. The feedback will give you a great overview of the user experience and prioritize fixes.
7.2 Accessibility Testing
Make your website accessible to users who have a disability, or who use a computer with a different browser. Check accessibility using guidelines like the WCAG, and also validate that devices that rely on accessibility features, such as screen readers, operate properly in each browser.
7.3 Testing on Different Devices
Perform the testing of your website on various devices such as desktops, laptops, and other portable devices like tablets and smartphones. Your website must be capable of functioning effectively on all resolutions and screen sizes. This shall be ensured through using the responsive design technique for consistency on different devices.
