5 minutes readKey takeaways INP replaced FID and measures responsiveness across the whole visit, not just the first input. Long tasks on the main thread are the usual cause, so break up JavaScript work. Field data is what counts, so verify improvements in real user metrics rather than the lab. Have you ever wondered why some websites… Read more »
5 minutes readKey takeaways POST parameters travel in the body, not the URL, which is why they do not appear in logs. The Content-Type header decides how the server parses them: form-encoded, multipart or JSON. Getting that header wrong is the usual cause of a server seeing an empty body. In today’s digital age, understanding the intricacies… Read more »

Use a public site to learn the framework, then point it at your own app. In this article, we’ll demonstrate how to create End-to-End (E2E) UI… Read more »
3 minutes readKey takeaways E2E tests earn their cost only on the journeys that make money; everything else belongs lower in the pyramid. Brittleness comes from locators and timing, so use stable test hooks and explicit waits. A suite people rerun until it passes is not a safety net, so fix flakiness rather than retrying. LoadFocus –… Read more »

Worth it when device-specific bugs matter; otherwise a hosted farm is cheaper. What is OpenSTF ? OpenSTF is an open source project that gives us the ability… Read more »
2 minutes readKey takeaways Puppeteer's click waits for the selector, but not for the element to be genuinely interactive. Wait for visibility explicitly when the page animates or loads content late. If a click does nothing, check for an overlay intercepting it before blaming the selector. LoadFocus – is a easy to use cloud testing tool, and… Read more »
3 minutes readKey takeaways WireMock lets you produce failures a real API will not give you on demand: timeouts, 500s, malformed bodies. Negative paths are where most production incidents live and where coverage is usually thinnest. Pin stubs to the real contract so a provider change breaks the test rather than production. Why do we need to… Read more »
