Mobile testing isn't just "web testing on a smaller screen" , it's a completely different beast. Here's what you're really up against.

- 100+ device combinations in the wild
- OS fragmentation across Android versions
- Performance that varies wildly between devices
- Network conditions constantly changing

1. Device Fragmentation
- The problem: Can't test on every device
- The solution: Focus on top devices only. Ask the PMs or the Analytics team about the most common devices used for your app
2. Network Conditions
- The problem: WiFi vs 4G vs 3G behavior differs dramatically
- The solution: Simulate network throttling in your tests. Use tools such Chrome DevTools, Charles Proxy or Fiddler
3. Touch Gestures
- The problem: Swipe, pinch, long-press all behave differently
- The solution: Use mobile-specific testing frameworks
4. App State Interruptions
- The problem: Calls, notifications, background tasks that kill your app session
- The solution: Test interruption scenarios explicitly. Focus on Phone Calls, Low Battery and Notifications
5. Performance on Low-End Devices
- The problem: Works on iPhone, crashes on budget Android
- The solution: Test on minimum spec devices from the top 5 most popular for your app

💡 𝐓𝐢𝐩:
Don't aim for 100% device coverage. Aim for 80% user coverage with smart device selection.
Focus your testing budget on devices your actual users have, not every device that exists.

Unlike software engineering or data science, QA Automation has no traditional university degree path. Most people stumble through trial and error for 12-18 months, piecing together knowledge from scattered YouTube tutorials and outdated blog posts.
If self-learning feels painfully slow or you're stuck not knowing what to learn next, structured guidance changes everything.
That's exactly why I created the QA AutoTest Accelerator - a training program that takes you from complete beginner to job-ready SDET in 3-4 months. You'll learn Python fundamentals, master Playwright automation, set up CI/CD pipelines, and get proven job-search strategies that actually work. Everything you need to go from zero experience to landing your first automation role.
⚠️ Price increase coming February 1st: Right now, you can enroll for for as little as $47 and lock in that rate permanently. Starting February 1st, new students pay $57. If you're serious about breaking into QA automation and building a stable, high-paying career, grab the discounted price while it's still available.
