Prioritize testing of critical functionalities such as forms, navigation, search, and interactive elements.
Test the entire path users take to make sure everything works well from beginning to end.
Focus testing efforts on the most important parts of the website’s function and user experience.
Create a Device Matrix
A device matrix lists the devices, browsers, and operating systems that need to be tested. This ensures comprehensive coverage across different user environments.
Prioritize Testing
Prioritizing testing involves focusing on the most popular devices and browsers used by your target audience. This makes sure resources are used well and problems that affect many users are fixed quickly.
- Use analytics to identify devices and browsers that are used by your website visitors.
- Prioritize devices and browsers that users have reported issues with.
- Stay updated with market trends and device/browser usage statistics to inform prioritization.
Automation and Manual Testing
Websites are ensured to function well and be user-friendly on various devices and platforms through manual and automation testing.
Automated Testing:
Automates repetitive tests, regression testing, and tests that require multiple iterations.
Executes tests faster than manual testing to provide quick feedback on potential issues.
Ensures consistent test execution and results to reduce human error.
Manual Testing:
It allows testers to explore and evaluate the website’s usability and user experience.
Tests scenarios that are difficult to automate or require human judgment.
Assesses visual appearance, layout, and user interactions.
Use automated testing for routine tasks regression testing and manual testing for exploratory testing and user experience evaluation.
Utilize Cloud Testing Platforms
Cloud platforms provide on-demand testing environments that can simulate various devices, browsers, and network conditions. They offer the following advantages:
