How did you install the application on devices?

Installing applications on devices usually occurs through several methods, depending on the device type and testing goals:

• Via app stores (App Store, Google Play) — for testing release versions.
• Using development tools: for example, Android Studio (adb install) for Android or Xcode for iOS, which allow direct installation of builds on the device.
• Via MDM systems (Mobile Device Management) — for corporate devices.
• Using CI/CD systems with automatic delivery of builds to test devices.

Example command for Android:

adb install path/to/app.apk

For iOS, Xcode or tools like TestFlight can be used to distribute test builds.

The choice of method depends on the testing goals, available tools, and infrastructure.
