Certified Tester Mobile Application Testing

Explore mobile device types—from basic to IoT companions—and compare native, browser-based, and hybrid apps. Learn testing across OS versions, hardware, screen sizes, sensors, and connectivity using simulators and real devices.

Develop a robust mobile test strategy by profiling markets, selecting key devices and OS versions, and prioritizing risks to ensure reliable app performance across networks and permissions.

Navigate testing across multiple platforms, OS versions, devices, screen sizes, and networks to ensure backward compatibility, performance, and smooth user experience while managing tools, SDKs, emulation, and distribution channels.

Identify key mobile testing risks and mitigations by selecting targeted devices and platforms, validating operating system compatibility and libraries, and simulating real usage patterns and preproduction releases.

Learn to use mobile analytics data to shape the testing strategy and plan; identify geographical location for audience, platform, operating system versions, device distribution, business models, and prioritize testing accordingly.

Test app interactions with device software, including notifications in foreground and background, privacy settings, deep linking, and cross-platform compatibility across OS versions and networks.

Explore various connectivity methods—2g/3g/4g/5g, wi-fi, nfc, and bluetooth—and validate apps under different network conditions using simulators and field testing to ensure seamless, data-loss-free reconnects with offline notifications.

Assess device hardware compatibility, app OS interaction, and connectivity to craft test levels, ensuring no data loss, graceful error handling, clear messaging, and a rich user experience.

Conduct additional test levels across performance, security, internationalization, accessibility, and usability, include field testing for real network conditions, and ensure store approvals with versioning for the APIs and libraries.

Explore mobile app test processes from planning to execution, covering device strategies, emulators, labs, operating system and sensor data challenges, field testing, test design, packaging, and provider guidelines for publishing.

Outline mobile test approaches across levels—from unit and integration testing to field testing, store approval, and user acceptance testing—considering architecture, sensors, simulators, API testing, automation, and continuous integration and deployment.

Master mobile app testing types and levels, including installation, stress, security, performance, usability, globalization, and accessibility, plus field, store approval, and post release testing.

Explore mobile development platforms like Android Studio and Xcode, and understand cross-platform tools and mobile web apps. Learn how readily available IDEs streamline design, coding, and testing without special packaging.

Explore emulators and simulators to model runtime environments, launch and install apps, test hardware-software interactions, and preview performance on real devices with GPS and bandwidth controls.

Explore mobile testing tools and environments for Xcode and Android Studio, using emulators and simulators; learn to set up a test lab, plan distribution, and field-test features.

Explore automation test approaches for mobile apps, including user-agent based testing and device-specific frameworks, with object IDs, operations, test reports, documentation, and CI integration.

Automate test execution by selecting suitable frameworks, identifying and operating on objects, and generating reports, while evaluating tools for reliability, speed, maintainability, and sustainable updates.
