Vibe coding is the practice of describing what you want in plain language and letting an AI assistant generate the code. Tools like Cursor, Replit, GitHub Copilot, and Google AI Studio brought this coding approach to millions of developers in 2025. It makes building software dramatically faster, but it creates a new problem: how do […]

You opened three SDET job listings, and each one reads like a different role. The first wants Selenium and Java. The second asks for Playwright with TypeScript. The third lists Kubernetes alongside test design and CI pipelines. So what does an SDET actually do, and is this the path you want to grow into? In […]

You ship a feature. Someone writes a manual test case in a spreadsheet, and someone else automates it later. The spec drifts from the manual case. The manual case drifts from the product. Nobody knows what’s actually covered. I wanted to fix that entire chain, not by hiring more people, but by rethinking who (or […]

AI is quickly changing how QA teams work due to its growing popularity, ease of use and adoption. The latest stage in the evolution of software testing is the independent AI agents that help software testers amplify their productivity by automating a variety of routine tasks, from test design to execution. Such agents can work […]

Writing manual test cases is one of those tasks that feels straightforward until it isn’t: every QA engineer on your team formats things slightly differently, context gets lost between features, and coverage gaps show up only when something breaks in production. My team solved this by building a reusable AI skill called test-case-drafting-template. This’s a […]

Most CI pipelines don’t have a screen. Your tests need to run anyway. That’s the core case for headless browser testing: it lets you run a full browser in an environment that has no graphical interface. No display server, no GPU rendering, no window to pop up in the middle of your pipeline. The browser […]

When your team runs an accessibility scanner before every release, it catches the missing alt text and the low-contrast buttons. That’s the basic check. A mature approach goes deeper: it shows which WCAG criteria you cover and which failures repeat across releases. And once you move to continuous deployment,

Testing every possible combination of inputs is theoretically the safest approach to software testing. It’s also practically impossible for anything beyond the simplest applications. Take a web form with five input parameters, each with four possible values. Exhaustive testing of all combinations requires 4^5 = 1,024 test cases. Add a sixth parameter and you’re at […]

Your suite was green on Friday. A designer renamed one CSS class over the weekend, and now 40 tests are red on Monday. No feature broke. A locator went stale. This is the maintenance tax every automation team pays, and self-healing test automation is the response. See how it works, what it can and can’t […]

When you’re starting a new JavaScript project, or fixing a Jest config that breaks every time you add an ESM-only package, the Vitest vs Jest question keeps coming up in team discussions.

When your team deploys code every day, you trust your CI pipeline to catch the bugs. You run unit tests, integration tests, and code reviews. But there’s a scenario most security programs haven’t been ready for. Continuous deployment moves faster than your pentest schedule the moment your team starts to scale.

Your application works fine with 100 users. But what happens when 10,000 show up at once? That’s the question scalability testing is designed to answer before real users find out the hard way. If you’re building software that needs to grow, scalability testing is one of the most important things you can do before a […]

Testing budgets are under pressure everywhere. Yet when teams cut QA the wrong way — fewer testers, skipped test cycles, deferred automation — defects escape to production and cost far more to fix than they would have in a sprint. Understanding the full defect management process helps teams see exactly where those extra costs accumulate. […]

For years, we treated automated tests as a regression safety net. That is what they are good at. The problem is simple: a test only walks the path you wrote for it. Hardcoded. Repeatable. Blind to anything outside the script. A test can pass on a screen where a real user is hopelessly lost, because […]

Explorbot is an open-source AI agent that explores web applications on its own. The first question people ask when they watch it run is always the same: how does it think so fast? They expect AI tools to be slow, hungry, and expensive. Explorbot is none of those things. The short answer is that Explorbot […]
