Best Practices for Cross-Browser Testing with Online Web Browsers
We will focus on most impactful best practiese here.
Regular Testing
Testing should be done permanently during the development cycle. All added features and introduced changes have to be tested under various browsers and on different devices. Regular testing will help catch compatibility issues at an early stage, hence reducing the risk of huge problems later. Regular testing also ensures that updating browsers themselves don’t break functionality on the website.
It shouldn’t be a one-time affair, meaning cross-browser testing can very well be integrated into your daily continuous integration (CI) pipelines so that source code modifications can be checked by running automatically. In this way, when cross-browser testing just becomes another to-do for developers as a part of the development process, it increases their bar in both quality and user experience.
Comprehensive Coverage
This is, for the most part, because one wishes to test on all major browsers and devices. These days, people use websites through different browsers that are available on the market, such as Chrome, Firefox, Safari, Edge, among others. Each of the mentioned browsers can act differently because of variations in its rendering, JavaScript engines, and support for web standards.
Testing in various mobile browsers is as essential as testing on desktop browsers. There is an increasing amount of traffic to the mobile platform each month, making it essential that your site functions just as well on mobile devices and their browsers. Test with Chrome for Android and Safari for iOS—these are the two most popular browsers in the mobile space.
It is also important to test the varied software environments: Windows, MacOS, Linux, iOS, and Android will bring their own peculiarities. An overall comprehensive testing strategy includes a blend of these systems to help serve universal websites.
Responsive Design
It should be responsive since there are a wide range of devices in existence. Websites should be in a position to adjust to different screens and different resolutions to make fine views. Some of the elements that will be tested in responsive design include the layout, images, fonts, form, and interactive buttons.
Very useful are tools that give the ability to test in real time with different screen sizes. That is when a developer can see how the website appears and its behavior on any kind of device—from small-screen smartphones up to large desktop monitors. This can help a lot in catching issues related to layouts and functionalities that might arise on specific devices.
Responsive design is something you can do with these types of things like Bootstrap or Foundation, so hope is never lost. Still, important testing must be done to assure this works. Responsive design is tested in both of the orientations because users are able to rotate devices now.
Utilizing Automation
Automation is a powerful tool in cross-browser testing. It allows for efficient and thorough testing by running scripts that simulate user interactions and check for issues. Automated tests can be executed repeatedly with minimal effort, saving time and resources.
Selenium is one of the most popular tools for browser automation. It supports multiple programming languages and can interact with various browsers. Other tools like Cypress and Puppeteer also offer robust automation capabilities.
Parallel testing is an advantage of automation. By running tests simultaneously across different browsers and devices, developers can get results faster. This speeds up the development process and helps in catching issues early.
While automation is beneficial, it is also essential to include manual testing. Automated scripts might miss certain user interface nuances that a human tester would catch. A combination of automated and manual testing ensures comprehensive coverage and high-quality results..
