Difference between Native, Web, and Hybrid Apps:

Native App: Built specifically for a particular OS (Android/iOS) using native languages (e.g., Java/Kotlin for Android, Swift/Objective-C for iOS). Native apps offer high performance and access to device-specific features.
Web App: A mobile-optimized website accessed through a browser. It’s responsive and can adapt to different screen sizes, but lacks direct access to device hardware like GPS or camera.
Hybrid App: Combines elements of native and web apps. It’s essentially a web app wrapped in a native app shell using frameworks like Cordova or Ionic, allowing limited access to device hardware.

Difference between Testing a Website and Testing a Mobile App:

Website Testing: Focuses on multiple browsers, screen sizes, responsiveness, and performance across desktop and mobile. Accessibility and cross-browser compatibility are important.
Mobile App Testing: Involves compatibility across various devices, operating systems, and screen resolutions. Includes testing hardware integration, network conditions, and app performance in different environments.

Difference between FCM and In-App Messaging:

FCM (Firebase Cloud Messaging): A push notification service allowing developers to send messages to users outside the app, even when it’s closed.
In-App Messaging: Displays messages only when the user is actively using the app. It’s generally used to engage users with updates, offers, or tips within the app.

Types of Ads and Types You’ve Tested:

Types of Ads: Banner ads, interstitial ads, rewarded video ads, native ads, and playable ads.
Tested Ads: You would specify which of these types you’ve tested, such as banner and interstitial ads, and outline the processes for functionality, click tracking, and integration validation.

Databases Used in Mobile Applications:

Common databases include SQLite, Realm, Core Data (iOS-specific), Firebase Realtime Database, and Room for Android.

Types of Mobile Technology Tested:

This could include native app frameworks (like Android SDK or iOS Swift), hybrid frameworks (like React Native or Flutter), and backend services such as Firebase, API integration, and notification services.

Types of Mobile Apps Tested:

Examples might include e-commerce, social networking, financial/banking, health & fitness apps, etc. Specify whether they were native, hybrid, or web apps.

Most Important Bug Identified:

Share a specific example, perhaps one where data was compromised or critical app functionality was blocked. Highlight the bug’s complexity and the steps you took to identify and report it.

Types of Mobile App Testing:

How You Test the Mobile App & Receiving the Build from the Developer:

Typically, developers provide the build through tools like Firebase App Distribution, App Center, or TestFlight for iOS and APK files for Android. Once received, testing is done on real devices or emulators, covering all specified test cases and user scenarios.
