- Test schedule: Create a test schedule that includes deadlines for each test phase.
3. Choosing the Correct Testing Approach
There are three main ways to perform cross browser testing:
- Manual testing: This includes manually testing a website or application across several browsers and devices. It provides a thorough insight into user interactions but is time-consuming.
- Automated testing: Uses specialized tools to run test cases automatically, increasing efficiency and coverage. However, it may require some initial setup and upkeep.
- Hybrid testing: Combines manual and automated testing to capitalize on the characteristics of both methodologies.
4. Use Cross Browser Testing Tools
Cross browser testing tools can greatly improve speed and test coverage. Consider using:
- LambdaTest: LambdaTest is a comprehensive platform that automates cross browser testing. It allows developers and testers to do scalability and performance tests of sites on mobile and other devices in several browser environments without requiring a large on-premise infrastructure. You can also test site on mobile devices both virtual and real devices.
- Selenium: It is a popular open-source tool for automated web application testing. One of its key characteristics is its ability to run cross-browser tests efficiently. Selenium WebDriver, one of the most important components of Selenium, interacts directly with the browser and allows you to control it programmatically. This implies that you may create test scripts that simulate user activities on several browsers and operating systems.
- Testim: This tool uses artificial intelligence to help build, execute, and maintain automated tests. It is compatible with CI/CD workflows and supports both web and mobile testing. Its AI-powered smart locators assist in detecting and keeping elements in your tests, even when the user interface changes. This considerably minimizes the maintenance effort.
- Ghost Inspector: You can use this tool to build automated browser tests without having to write any code. It enables visual testing and works with a variety of project management and CI/CD platforms. It allows testing on several browsers and screen sizes, including mobile and tablet views. This provides extensive coverage for many user scenarios.
