TL;DR: A root cause analysis (RCA) template gives QA teams a repeatable structure for tracing defects back to their actual origin instead of patching surface symptoms. The best templates combine the 5 Whys technique, fishbone diagrams, and an action tracking section. This guide includes ready-to-use templates, real software testing examples, and shows how ContextQA’s automated […]
TL;DR: Browser compatibility is not solved. Safari’s WebKit engine is maintained independently by Apple and runs on every iOS device by policy — meaning any WebKit rendering bug affects 100% of your iOS users regardless of which browser they use. A 2025 survey found 68% of users abandon a site after encountering just two rendering […]
TL;DR: Your performance tests can pass while production breaks. Not because the tools are wrong — because teams use load testing when they need real-user monitoring, and Lighthouse when they need INP measurement. This complete guide maps every major performance testing tool to the specific question it answers, covers the March 2024 Core Web Vitals […]
TL;DR: Mobile test automation fails more often than web automation — not because the tools are bad, but because teams apply web testing logic to a fundamentally different environment. The JetBrains Developer Ecosystem Survey 2024 found 43% of mobile developers cite testing as their top productivity bottleneck. This guide covers framework selection by app type, […]
TL;DR: Framework selection for automated testing depends on four variables: application type, team language proficiency, test type distribution, and CI/CD integration requirements. Stack Overflow’s 2024 Developer Survey and JetBrains State of Developer Ecosystem provide the adoption data. ThoughtWorks Tech Radar documents migration patterns. Playwright leads end-to-end for new projects. Jest leads JavaScript unit testing. No […]
TL;DR: Shift left testing moves quality validation earlier in the development lifecycle. IBM Systems Sciences Institute data documents a 100x cost escalation for defects fixed in production versus defects found in the design phase. DORA research shows organizations practicing shift left testing achieve elite deployment frequency at four to five times the rate of organizations […]
TL;DR: Testing in production means deliberately running test activities against live systems using controlled techniques: canary releases, feature flags, synthetic monitoring, and chaos engineering. DORA research shows elite engineering teams deploy 182 times more frequently than low performers and rely on production testing practices to maintain quality at that velocity. Pre-production testing alone cannot replicate […]
Let’s be honest: we live on our phones. We use them for everything from ordering food and booking flights to managing our finances and staying in touch with friends. And with so much of our lives happening on our phones, it’s more important than ever for mobile apps to be fast, reliable, and easy to […]
Chances are, Salesforce is the lifeblood of your business. It’s where you manage your customer relationships, track your sales, and run your marketing campaigns. So, when something goes wrong, it can have a major impact on your bottom line. That’s where Salesforce testing best practices come in. A solid testing strategy can help you catch […]
Let’s be honest, nobody really likes manual regression testing. It’s tedious, time-consuming, and let’s face it, a little bit boring. But it’s also a necessary evil. You have to make sure that your new features haven’t broken anything, and that means re-running a whole bunch of tests every time you release. But what if there […]
So, you need to do some performance testing. You know it’s important, you know it can save you from a world of hurt down the road. But where do you even start? There are a million and one performance testing tools out there, and they all claim to be the best. How do you cut […]
If you’ve been in the QA and web development world for a while, you’ve probably heard of Angular. But you might have also heard of its predecessor, AngularJS. And if you’re a tester, you might be wondering what the difference is and how it impacts your testing strategy. Well, you’ve come to the right place. […]
