Testing strategy guides — how to plan, prioritize, and structure QA for your team or product.
Testing Strategy
Netflix's infrastructure team had a problem in 2010: they couldn't be sure their systems would survive an AWS outage. Their solution — a tool that randomly terminates production instances — became Chaos Monkey, and the discipline around it became chaos engineering. The core idea: instead of hoping your
Security Testing
Security testing bolted on at the end of the development cycle catches vulnerabilities too late — when fixing them means rework, delayed releases, and expensive patches. The solution is shifting security into the CI/CD pipeline, where it runs automatically on every change and catches issues when they're cheapest
Testing Strategy
Most startup founders skip testing because it feels like it slows them down. Then they spend entire weekends debugging production issues that a 10-minute test would have caught. This guide gives you a minimal, practical testing strategy that protects your core flows without requiring a QA team or dedicated test
Testing Strategy
Your app works fine with 10 users. You launch a Product Hunt campaign, 500 people hit it simultaneously, and it falls over. Load testing finds that breaking point before your users do. This guide covers what load testing is, which tools to use, what metrics matter, and how to run
Testing Strategy
Functional testing verifies your application does what it's supposed to do — that clicking "Buy" actually charges a card, that login rejects wrong passwords, that checkout calculates tax correctly. It's distinct from performance or security testing: it's the core "does this feature
Test Automation
Manual testing doesn't scale. Every time you push code, someone has to click through the app to make sure nothing broke. Automated testing replaces that clicking with scripts that run in seconds. This guide covers what automated testing is, what to automate first, the right tools for each
Test Automation
Every feature your users love is held together by API calls you never see. When one of those calls fails silently, your frontend shows stale data, your mobile app crashes, and your users think it's a bug in the UI. API testing catches the real failures — before your
Testing Strategy
Your scripted tests cover every scenario you thought of when you wrote them. Exploratory testing finds the scenarios you didn't think of — the ones users will discover on day one. It's not unstructured chaos; it's skilled investigation. Key Takeaways Exploratory testing finds bugs that
Test Automation
A bug caught at commit time takes 10 minutes to fix. The same bug caught in production takes 10 hours. CI/CD testing is the practice of moving that discovery window as early as possible — so every change is verified before anyone else has to deal with it. Key Takeaways
Testing Strategy
The average cost of a data breach is $4.88 million. The average cost of catching a security vulnerability during development is a one-hour code review. Security testing is not a separate phase you add at the end — it's the practice of making the expensive option disappear. Key
Testing Strategy
Everyone calls them mocks. They're not all mocks. Dummy, Stub, Spy, Mock, Fake — these five types of test doubles serve different purposes, and using the wrong one produces tests that either verify nothing or are so tightly coupled to implementation that they break every refactor. Key Takeaways "
Testing Strategy
Your QA team passed every test. Your users still found a broken checkout. Acceptance testing is the last gate between your code and your customers — it answers the only question that actually matters: does this software do what the business needs it to do? Key Takeaways Acceptance testing validates business
