Strategies that Make Cross-Browser Testing Successful

When it comes to website testing, cross-browser testing is considered the most important aspect because it decides the availability or accessibility of the site to users. For example, if you have an eCommerce site that works fine on one browser but fluctuates or doesn’t represent products accurately on another browser.

So, what could be the reason behind it?

It’s simple! Your website is not compatible across all browsers. This happens because every browser has its unique rendering engine that represents content differently. That’s why QAs need to perform cross-browser testing to ensure every user gets the same experience across your site.

There are millions of websites in the world, but not even half of them are fully active. Most websites fail to work due to browser compatibility or responsiveness issues. Although QAs and testers make regular efforts to keep cross-browser testing up to the mark, they need a solid strategy that works for a longer period while avoiding any obstacles.

In this article, we have mentioned eight effective strategies that you can follow for successful cross-browser testing.

Decide the Ideal Browsers for Testing

Before beginning with cross-browser testing, selecting the right combination of browsers and devices is vital. There are multiple browsers available out there, and not every one of them is used for browsing the internet or sites. Besides, many browsers reject and accept various CSS and JS properties over time with their new versions.

You need to identify the browsers that customers can use to access your site or web app. It is one of the essential components of the cross-browser testing process. The best way to decide on browsers is to consider your targeted audience. For instance, if your targeted audience uses only Firefox or Chrome browser, then create your browser list accordingly.

Once you finalize a list of browsers and devices of your targeted audience, you need to analyze the changing requirements and behavior of the browsers. Furthermore, you need to ensure that whenever a new version of the listed browser is available, you test your web app functionality across it.

Validate Website Code Continuously

Code validation is the process of validating the website code as per W3C standards. As a web developer, it’s extremely important before starting the testing process. A well-formatted and validated site makes it easy to test browser compatibility and brings a lot of freebies with it. For instance, it improves search engine optimization to attract more visitors, quick maintenance, convenience, etc.

To validate the code for your site and make it browser compatible, you can use validator tools available online. However, you can also use test editors that provide the highlighting functionalities to find invalid code on the site.

Decide What to Test

Well, the primary goal of cross-browser testing is to test the web across all browsers and devices, but it’s not always achievable. Most teams don’t have the required resources or knowledge to meet all the requirements. In such cases, you need to redefine the scope of cross-browser testing. One great way to simplify this process is to identify the most crucial areas for cross-browser testing. Some of the essential components of cross-browser testing include:

  • Check for button and checkboxes alignments on the web pages, as they often fluctuate on different browsers
  • Verify the web app doesn’t display any unsupported error for video and image rendering on the browsers
  • View and define the value of drop-down menus on the web app
  • Ensure the zoom-in and zoom-out functionality of the web app works fine across the browsers
  • The font size of the content is responsive based on the devices the website is accessed

These are a few common things that need to be tested for cross-browser testing of a web app. It will ensure that your web app provides a seamless experience to all users.

Use Emulators and Virtual Environments

Many testers face cross-platform-related issues while running test cases across different browsers. For instance, if you have a small application on windows, you can easily test it across Firefox, Chrome, IE, and other browsers. However, if you’re working on Mac, then it’ll not be easy to run tests on Windows-based browsers.

An alternative to this problem is using virtual environments and emulators that provide you with a unique version of operating systems with different sets of browsers. In addition, you’ll get access to extensions with Chrome browser to emulate other browsers. Virtual machines or emulators are a great solution to test your application across multiple browser combinations.

Follow the Mobile-first Approach

With the increasing usage of mobile devices in the world, companies are following the mobile-first approach to test their web applications. These days, users mostly rely on their smartphones to browse the internet, shop for products, or do other internet-related things. This makes it crucial for developers to build mobile-responsive applications. However, while performing cross-browser testing for mobile devices, testers face a lot of issues.

For instance, some emulators or virtual devices might not provide the best results to test web apps on mobile devices. An ideal approach to test web apps across mobile devices is to use sample devices if it comes under your budget. For example, you can easily acquire iOS devices because they’re very limited.

However, if you test Android devices, it will be costly and take a lot of time. So, you can use analytics to find what Android devices will be used by customers and then plan your testing accordingly.

Select the Ideal Method for Cross-Browser Testing

Cross-browser testing is a comprehensive process that can be time-consuming with manual methods. Therefore, it’s always recommended by professionals to use automation when performing cross-browser testing. Automation testing helps you cover a wide area of your web apps while giving you enough time to focus on other testing areas.

Along with that, it allows you to execute tests in parallel, which means you can test multiple browser combinations at once on a single system. Combining automation with parallel testing will bring cross-browser testing to the optimum level. You can even enhance your CI/CD pipeline with automation and parallel testing.

Choose the Right UI Framework for Web App Testing

One thing that can change your web app cross-browser testing process entirely is the test framework. Choosing the right framework can do all the work for you while making your cross-browser testing easier. And there is no better open-source solution than Selenium. It is one of the most popular, robust, and reliable UI testing frameworks to test web apps.

QAs and developers widely adopt Selenium across the world to test web app cross-browser testing. It is a suite of four different utilities that can be used for various testing requirements. For example, Selenium WebDriver is used to test web apps, as it accepts commands and sends them to the browser to execute.

Selenium can save you a lot of time while enabling you to focus on other tasks that require full attention, like performing manual tests, analyzing reports, etc.

Use an Automation Testing Tool

If you’re going ahead with automation for cross-browser testing, then you need an excellent tool. Cross-browser testing is only effective if you use an automation testing tool that can test your web app across multiple browsers, operating systems, and devices. Although there are a variety of tools to choose from, not all of them are ideal for you. Besides, if you’re on a limited budget, you need to make your selection carefully.

If you’re looking for a cost-efficient tool that provides all the required functionalities for cross-browser testing, LambdaTest is a great option. LambdaTest CBT and Automation allows you to test your web app across more than 3000 browser combinations while providing your detailed record and playback feature. It is even available with a trial version that allows you to test limited functionalities of your web app.

Cross-browser testing should be performed at the earlier stages of development so that you can deliver an excellent and viable product to the market. Moreover, the entire testing process should be repeated once the development phase is over.

Wrap Up

Cross-browser testing is a crucial task for the success of a web application. It works as the bridge between engaging customers and their purchase decision on your site. But, executing cross-browser testing is not that simple; you need a solid strategy for it. For most QAs, it’s not easy to create and cope-up with a cross-browser testing strategy. This article is designed for those QAs to guide them throughout their cross-browser testing of web apps.
