1. Executive Summary

This test plan covers comprehensive testing of a native mobile e-commerce application for iOS and Android platforms. The app enables customers to browse products, manage wishlists, place orders, and track shipments on smartphones and tablets. Testing will validate functionality, performance, usability, and platform-specific behaviors across multiple devices and OS versions.

Criticality: HIGH — Mobile commerce is primary revenue driver; poor app quality directly impacts user retention and revenue.

2. Objectives

• Validate core e-commerce workflows (browse, search, add to cart, checkout, order confirmation)
• Verify app stability and performance on target devices and OS versions
• Confirm proper handling of device-specific features (camera, location, notifications, permissions)
• Test network resilience (WiFi, cellular, offline scenarios)
• Validate UI/UX consistency across form factors (phones, tablets)
• Ensure accessibility compliance (VoiceOver, TalkBack, text sizing)
• Test in-app payment integration
• Verify deep linking and push notification functionality

3. Scope

• User account settings

4. Test Strategy

Testing Types by Platform

Type	iOS	Android	Focus
Functional	30%	30%	Core workflows, feature parity
Regression	20%	20%	Previous releases stability
Performance	15%	15%	App launch, scroll, memory usage
Platform-Specific	20%	20%	iOS notch/safe area; Android permissions
Network	10%	10%	WiFi/cellular/offline resilience
Accessibility	5%	5%	Screen readers, text sizing

5. Risk Assessment

Risk	Probability	Impact	Mitigation
App crashes on specific OS versions	Medium	High	Test matrix coverage, crash reporting (Firebase)
Memory leaks during extended use	Medium	High	Profiling tools (Xcode Instruments, Android Studio Monitor)
UI layout broken on tablet/large screens	Medium	Medium	Layout testing on varied screen sizes
Push notification delivery failures	Low	Medium	Testing with Firebase Cloud Messaging
Permissions denied → app breaks	Medium	Medium	Test all permission denial scenarios
Network timeout handling	Medium	Medium	Throttle network, test error messaging

6. Entry Criteria
