How to Perform Cross-Browser Testing?
This is how you can perform cross-browser testing –
Cross-Browser Compatibility
Cross-browser compatibility allows an online program or website to function with several browsers and versions. Because users may access websites using many browsers, operating systems, and gadgets, each device may display online pages differently. Cross-browser compatibility is essential to ensure a consistent user experience.
Different browser rendering engines, CSS support, and JavaScript execution might cause compatibility issues. Teams must grasp these hurdles to identify potential issue areas for cross-browser testing.
Identifying Target Browsers and Platforms
Cross-browser testing must start with identifying which browsers and systems require testing. This decision usually depends on market share and intended audience. Developers should prioritize Chrome, Firefox, Safari, Edge, and their numerous variants.
Mobile browsers like Chrome on Android and Safari on iOS are crucial due to the rise of mobile web usage. Choosing the target browsers simplifies testing and ensures the app is tailored to the audience’s favorite platforms.
Setting Up a Testing Environment
Cross-browser testing requires a suitable testing environment. This may be done locally or in the cloud. Virtual machines or emulators for multiple browsers and operating systems might take time and resources to set up locally.
Cloud-based solutions provide instant access from many places and devices without laborious setup. These solutions offer real-time automation and integration with standard CI/CD procedures, making cross-browser testing faster for teams.
Executing Manual and Automated Tests
Cross-browser testing may be done manually or automatically. Manual testing requires multiple browsers to connect to the web app and compare its appearance and functionality. Experimental testing and detecting UI issues that automated tools overlook work well with this strategy.
Test scripts for automated testing employ Selenium, Cypress, or Playwright to repeat the same steps in multiple browsers. Computerized tests are excellent for testing failure and ensuring browser compatibility. Much time and effort is saved.
Debugging and Fixing Issues
Once problems with compatibility are found during tests, they need to be debugged and fixed. Chrome DevTools, Firefox Developer Edition, and Safari Web Inspector let you debug JavaScript and CSS and learn about web page production. With these tools, developers can find out why compatibility issues are happening and fix them.
For example, they can use CSS prefixes, polyfills, or JavaScript packages that work across browsers. Fixing problems quickly ensures that the app works smoothly on all target computers, lowering the chance that users will be unhappy.
Leveraging Responsive Design and Testing
Cross-browser testing requires a responsive design to adapt web apps to multiple screen sizes and devices. Testing responsiveness ensures a website’s layout, pictures, and interactive components work across screen resolutions.
Chrome’s responsive design mode and cloud platforms imitate screen sizes and assess responsiveness. By employing responsive design and testing, teams can ensure their applications run on PCs, tablets, and smartphones independent of browser or OS.
Continuous Integration and Testing
Cross-browser testing must be part of CI/CD to maintain application quality. Running and integrating tests to CI/CD helps teams find compatibility issues early in the development cycle. This strategy allows authors to obtain feedback immediately and resolve errors before production.
Cross-browser tests may be automated using Jenkins, GitLab CI, and Travis CI, linked to testing platforms. Testing becomes more accessible and more effective. Continuous development and testing raise user satisfaction by maintaining app quality across sites and devices.
Best Practices for Cross-Browser Testing
Here are some of the best practices for cross-browser testing –
