Cross Browser Compatibility Testing Checklist: The Do’s and Dont’s

Browser compatibility testing checklist? Website testing checklist? Or website QA testing checklist? Although the names vary, what stays common is that the need and importance of this checklist will define your site’s veritable success.

Every year, more and more digital devices are launched, each with its specific combination of browsers, operating systems, and screen resolution. This makes the job of a tester infinitely more complex. However, thanks to cross-browser testing tools like Testsigma, testing across different browsers, devices, and resolutions are simple. It takes only a few seconds to get a detailed analysis of other formats, letting you tailor your pages accordingly.

As a web developer or product manager, you must use browser compatibility testing to guarantee that your website is compatible with all technologies. As a result, organizations must perform cross-browser compatibility testing before any product launch.

Why do You Need Cross-Browser Testing?

Each mobile phone has a unique operating system, default browser, and screen resolution.

To begin with, you should use it to provide your clients, customers, and visitors with the most satisfactory possible experience. With that much versatility, how can you ensure that your website or application looks and performs correctly across a wide range of browsers, devices, and operating systems?

Cross Browser Compatibility Testing assures that everything functions flawlessly regardless of the operating systems, devices, or browsers used to access it.

A list of tools is available to help Developers determine whether a specific technology on a website is compatible with a particular browser.

For example, HTML5 Please checks if HTML5, CSS3, and a simple search of a property, parameter, or feature will reveal which browsers and versions support that technology. Also, check if other features are ready for usage and, if so, how you should use them. These tools can assist you in making better judgments about website and application development.

Importance of Browser Compatibility Testing

When developing a new website, cross-browser compatibility is a frequently forgotten stage. Designers and developers will often use a single browser to create it — and they may rapidly test it on a few more browsers before declaring the project complete. This is sufficient for simple non-mission-critical sites, but if you’re constructing more complicated ones, your site may look drastically different in other browsers.

Of course, testing every page on every potential device, platform, and browser combination is practically impossible and prohibitively expensive. So, how can we ensure that our site looks and behaves exactly as we intended on as many browsers as possible?

That’s where Cross Browser Compatibility Checklist comes to play, explaining The Do’s and Don’ts.

A Strategy, A Tool, and a Noteworthy Website:

All About Cross Browser Testing Checklist You Need to Know:

There are some prerequisites for Cross Browser testing that you should review before beginning cross-browser testing.

• Define the scope of testing—how much testing will be done, when it will be done, and how much functionality will be covered?
• Create a plan for cross-browser testing- Which browsers (and versions thereof) will be used, as well as which operating systems and devices? What combinations will be tested?
• Select the appropriate tool- Choose the best automation cross-browser testing tool from the options offered. During the selection process, we may ask questions such as.

Consider the cross-browser compatibility testing checklist into parts, which will help you execute testing in the best way forward:

• By Testing General Browser Compatibility
• Validating Layout and Design
• Ensuring the Functional Compatibility

Cross Browser Testing Checklist for General Browser Compatibility

This website Testing checklist tests the critical features for the website to work correctly. Some of the most important ones are listed below:

• Validate the CSS, HTML and XHTML. This will ensure that all code meets relevant standards and that there are no open tags.
• Validate the SSL certificate. Some SSL certificates are not compatible with all browser versions, so checking this before proceeding is essential. You also need to know who owns the website domain you’re using.
• Take care of visual elements; validate the fonts, fields, and design.
• To ensure that web pages are displayed correctly on various screens with different size ratios and resolutions, it is crucial to verify that they work effectively on multiple screens. Browsers may apply their default styles to your website by default. Chrome, for example, will add a default margin to your website – a minor but perceptible difference if you pick a darker background color.

To resolve this, you can use some code to reset the defaults, removing the mystery of why some styles differ in different browsers.

• It is also essential to verify the DOCTYPE instructions on every webpage. Define the language in which the code is written at the start of your HTML file(s) so that browsers can appropriately read it. This ensures that all browsers will parse the web pages similarly.
• Since API calls can differ between browsers, you must be cautious if your application uses APIs. It would be best to ensure that the APIs used are compatible across various browsers to avoid compatibility issues.
• Another essential thing to do is verify the HTML’s X-UA-Compatibility meta tag. This helps to overturn a user’s compatibility view setting in Internet Explorer for your website.
• Both points are crucial for ensuring that your website is accessible and secure for all users.
