What can be tested in a hybrid application?

In a hybrid application, the following can be tested:

• Functionality:
  • Operation of all interface elements (buttons, links, forms, toggles).
  • Application logic verification.
  • Backend interaction (sending data, receiving responses).
  • Correct execution of business scenarios.
  • Autonomous mode operation (if available).
• User Interface (UI) and User Experience (UX):
  • Display of elements on different devices (phones, tablets).
  • Design responsiveness to various screen sizes and orientations (portrait, landscape).
  • Compliance with design mockups.
  • Smoothness of animations and transitions.
  • Navigation ease.
• Performance:
  • Page and data loading times.
  • Device resource consumption (CPU, memory, battery).
  • Response speed when interacting with elements.
  • Application performance under load.
• Compatibility:
  • Correct operation on different OS versions (iOS, Android).
  • Compatibility with various webview engines.
  • Compatibility with different device models.
• Security:
  • Protection of user data.
  • Handling authentication and authorization.
  • Vulnerability checks (e.g., XSS inside webview).
  • Correct error handling related to security.
• Integration:
  • Interaction with native device functions (camera, geolocation, notifications).
  • Working with external services and APIs.
• Reliability and fault tolerance:
  • Behavior when losing internet connection.
  • Handling incorrect input data.
  • Reaction to low battery level or insufficient memory.
• Installation and updates:
  • Correct installation from app stores.
  • Smooth and correct updates.
  • Ability to roll back to a previous version (if necessary).

It is important to consider the features of hybrid applications, such as the use of web technologies inside a native container, which may require combining approaches to testing web and native applications.
