Manual and Automated Testing Approaches
A combination of manual and automated testing techniques is crucial for thoroughly validating your website’s consistency across different devices. Each approach has its strengths and uses cases.
Manual Testing
Manual cross-device testing involves having human testers physically interact with and assess your website on a selection of actual device hardware and software configurations, such as desktops, laptops, tablets, smartphones, etc.
The benefits of manual testing are:
- Getting real-world feedback on the complete user experience.
- Identifying subtle visual, functional, or performance issues machines may miss.
- Exploring less common or complex user scenarios.
- Testing across diverse accessibility situations.
While laborious, manual device testing is indispensable for catching unpredictable edge cases. Many teams leverage crowd-sourced manual testing services.
Automated Testing
Conversely, automated cross-device testing uses scripted tests that can be run repeatedly across multiple environments. Computerized tests are efficient for regression testing changes and validating core functionality.
Benefits include:
- Running Tests in parallel across many device/browser combinations.
- Quickly testing common user workflows like form submissions.
- Catching layout bugs through visual regression testing.
- Quickly repeating tests for every code change.
Popular automated test frameworks like Selenium and Appium make building cross-device test suites that integrate into CI/CD pipelines relatively straightforward.
Combining Approaches
The optimal strategy leverages the strengths of both manual and automated testing. Automated tests are used as a regression safety net, while manual testing is dedicated to exploratory scenarios and quality assurance. Maintaining this balance is critical for comprehensively validating cross-device consistency and usability.
Optimizing for Different Devices
Here are some critical points on optimizing for different devices when it comes to cross-device web testing and designs:
