Quality Assurance: Fundamentals of Cross-Browser Compatibility and its Testing

Quality Assurance (QA) is a process aimed at ensuring the quality of software development and functioning. One important aspect of QA is cross-browser compatibility, which guarantees the correct display of a website or web application on different browsers and platforms.

Cross-browser compatibility becomes particularly relevant in light of the variety of browsers used by users. Each browser has its own features and technical characteristics, so web developers need to test their product on different browsers to ensure that it works correctly and consistently everywhere.

The main stages of cross-browser compatibility testing are as follows:

1. Identification of target browsers. It is important to identify the main browsers used by users. This can be done by analyzing website visitor statistics or consulting with marketing and analytics specialists.

2. Test plan development. At this stage, test scenarios and functional requirements to be tested on each browser are defined. The test plan may also include criteria for assessing quality and test completion deadlines.

3. Testing on real devices. To achieve the most accurate results, it is recommended to conduct testing on real devices rather than emulators. This allows for differences in display and performance on different devices and operating systems.

4. Evaluation of test results. After testing is complete, it is necessary to analyze the obtained results and assess whether the product meets the specified requirements. Special tools for comparing website display on different browsers can be used for this purpose.

5. Bug fixing. If any errors or deviations from the requirements were discovered during testing, they need to be fixed. In the process of fixing bugs, developers need to prioritize and determine which errors require immediate attention and which can be deferred.

6. Retesting. After making the necessary fixes, it is important to retest the product on all target browsers to ensure that all errors have been resolved.

Benefits of cross-browser compatibility:

- Increased audience. Cross-browser compatibility allows your website or application to work on different platforms and browsers, expanding your audience and increasing the number of potential users.

- Improved user satisfaction. When users see that your website works without errors and performs consistently well on all browsers, it increases their satisfaction and trust in your company.

- Enhanced SEO optimization. Cross-browser compatibility also contributes to improving the SEO optimization of your website. Search engines value sites that display well on different devices and browsers.

- Increased competitiveness. In the modern web space, cross-browser compatibility is becoming increasingly important, so increasing the competitiveness of your website or application includes ensuring its proper functioning on different browsers and platforms.

In conclusion, cross-browser compatibility is one of the fundamental principles of quality assurance. Checking the proper functioning of a website or application on different browsers and devices allows you to improve the user experience, attract more users, and increase the competitiveness of the product. Therefore, cross-browser compatibility testing should be included in the software development process.
