Best Practices for Automated Mobile App Testing

To ensure effective automated mobile app testing, engineering teams should adhere to the following best practices:

1. Make Application Testable: Collaborate with testing teams to set guidelines that make applications ready for testing. For example, developers should assign unique IDs to elements for easy testing.

2. Avoid Overusing XPath: While XPath can be useful for navigating elements, excessive usage can impact performance—order selectors so that more efficient locators like ID are prioritized over XPath.

3. Utilize Accessibility IDs: Instead of relying heavily on XPath, use accessibility ID locators where possible. Setting accessibility IDs on elements makes them more testable and expands the testing scope.

4. Consider View States: Set up the Application's view state to avoid duplication in test cases. This ensures that testing begins at the necessary point, saving time and resources.

5. Emulators and Simulators: While useful for initial testing, emulators, and simulators have limitations in replicating real user conditions—test apps in less-than-ideal circumstances to ensure satisfactory user experiences.

Following these best practices can lead to more efficient and effective automated mobile app testing, resulting in higher-quality applications.
