When developing tests, what is more important to you — testing web application interfaces or mobile applications?

The choice between testing web application interfaces and mobile applications depends on the project context and testing goals.

• If the main audience uses the web application, it is more important to focus on the web interface, testing cross-browser compatibility, responsiveness, and functionality.
• For mobile applications, it is critical to test platform-specific features: different OS versions, performance, and interaction with hardware capabilities.

Ideally, both options should be covered, but when limited, the priority is determined by the target audience and business goals. For example, if the product is a mobile application, testing the mobile interface is more important.

It is also important to consider that testing methods differ: Selenium is often used for web testing, while Appium or Espresso are used for mobile testing.

Thus, the importance depends on the project specifics, but always strive to cover the interfaces that are most critical for users.
