2 minutes readKey takeaways FMP tried to capture when the main content appeared, rather than the first pixel. It proved hard to measure consistently and has largely been replaced by LCP. Use LCP for anything current; FMP appears mainly in older reports. Time to First Meaningful Paint (TTFMT) is a modern performance metric introduced by few engineers… Read more »
4 minutes readKey takeaways A good scenario mirrors real traffic mix, not the endpoint that is easiest to script. Include think time. Removing it produces a load pattern no user creates. Start below expected peak and ramp, so you can see where behaviour changes. Congratulations on completing your first load test with LoadFocus! But what comes next?… Read more »
3 minutes readKey takeaways Staging exists to mirror production closely enough that surprises surface before release. The closer the parity, especially in data and scale, the more useful it is. A staging environment that drifts from production gives false confidence. LoadFocus – is a easy to use cloud testing tool, and you don’t need any setup, it… Read more »
2 minutes readKey takeaways Automated visual comparison catches layout regressions no functional test asserts on. Compare the same viewport and state, or the diff is dominated by noise. Review differences rather than gating on pixel equality, which fails constantly. With LoadFocus you can visually compare your staging website with your production website automatically, following these steps below: Steps… Read more »
2 minutes readKey takeaways Image comparison catches visual breakage that assertions never check for. Set a difference threshold, or font rendering will fail the suite on every machine. Run in a consistent environment; a different OS produces different pixels. Jest is a complete and easy to set-up JavaScript testing solution which also provide a Snapshot Testing built-in… Read more »
2 minutes readKey takeaways Pixel comparison catches visual regressions that functional tests never assert on. Set a tolerance, or antialiasing and fonts will fail every run. Compare identical viewport and state, otherwise the diff is dominated by noise. Keeping your web applications visually consistent across various platforms and updates is crucial yet challenging. Thankfully, screenshot comparison tools… Read more »
2 minutes readKey takeaways A screen recording captures the exact sequence that reproduces a bug, which a description rarely does. Record on the device rather than an emulator when timing or gestures matter. Keep clips short and start just before the problem, so the reviewer sees it immediately. There are quite a few applications on the market… Read more »
