Quality Assurance (QA) is the foundation of delivering high-quality software. In this category, we cover core principles, methodologies, and best practices that every QA professional should know. From defining test plans and executing test cases to understanding software quality standards, this section helps testers build a strong foundation in QA. Whether you’re a beginner learning the fundamentals or an experienced QA looking to refine your testing processes, you’ll find practical insights, strategies, and techniques to improve efficiency and effectiveness in your QA role.
A meme about simple math uncovered a QA oversight most testers never check: operator precedence and logic grouping. Here’s what I learned—and why ignoring this can quietly wreck fintech apps.
Most testers only follow the tools, not the logic. This breakdown exposes where each testing methodology fits—and how to use them like someone who’s been blamed in UAT and survived it.
We didn’t just run PageSpeed and Lighthouse. We debugged QAJourney.net like any product — cross-browser, tool-by-tool, fix-by-fix. Here’s how QA thinking found what performance audits couldn’t.
You don’t need to be a certified automation engineer to write useful Playwright tests. I started with local scripts, flaky results, and real QA problems. Here’s how I made automation work without overengineering it—and why manual QA still wins in 2025.
Even if you’re a manual tester, knowing just enough Bash and Node.js can change your workflow. Skip the bloat. Learn how to automate tasks and debug faster.
Use Playwright to automate your QA workflow across real-world test cases—without needing CI/CD. We cover everything from form validation to iframe handling, and it’s all open-source via our repo and test sandbox.
Cypress automation testing isn’t just about running tests—it’s about building resilient, scalable test suites that integrate seamlessly with modern web applications. In this guide, we dive deep into real-world testing scenarios, including form validation, network delay handling, shadow DOM, iframe interactions, broken link detection, and accessibility testing. You’ll also get access to a live QA testing playground and a GitHub repo with Cypress scripts ready to use.
Selenium is still one of the best ways for QA testers to start automation—no CI/CD required. This hands-on guide uses playground.qajourney.net for real testing, with Selenium IDE, WebDriver, XPath, JS, and advanced techniques to help you transition from manual to automation with confidence.
QA testing isn’t just about clicking buttons—it’s about ensuring performance, security, and functionality. This guide explores the essential QA tools that every tester should use, from Selenium for automation to Burp Suite for security testing.
QA is evolving beyond just using tools—it’s about embedding quality into Agile, Shift-Left, and API-first strategies. Learn how to apply advanced QA techniques that go beyond execution and into leadership.
