5 minutes readKey takeaways APM tells you what is slow in production; load testing tells you what will be slow before release. Choose on trace quality and how quickly you can get from an alert to the offending call. Cost scales with data volume, so sampling policy matters as much as the feature list. Imagine your users… Read more »
6 minutes readKey takeaways A smoke test answers one question: is this build worth testing further. Keep it fast and shallow, covering the critical path only. It is not a regression suite, and treating it as one defeats the purpose. Smoke testing is a quick check of a software build’s most essential functions, run to confirm the… Read more »
19 minutes readKey takeaways An online tester removes local setup, which matters most when you are debugging someone else's API. Test error paths and auth, not just the documented happy request. Save requests as a collection so a one-off check becomes a repeatable test. When your application crashes during peak traffic or returns cryptic error messages to… Read more »
4 minutes readKey takeaways Unit tests check a piece in isolation; functional tests check behaviour a user would notice. Unit tests are fast and precise, functional tests are slower and closer to real risk. You need both, in different proportions, rather than choosing between them. Testing software is a lot like checking your homework before turning it… Read more »
3 minutes readKey takeaways CSV data gives each virtual user its own inputs, which is what makes a run realistic. Set the sharing mode deliberately: all threads, per group and per thread behave differently. Decide what happens at end of file, or threads quietly reuse the same rows. If you’re aiming to simulate real-world user behavior in… Read more »
5 minutes readKey takeaways Batch testing groups related cases into one run, which cuts setup cost and shortens feedback. It suits stable, repeatable suites; it is a poor fit for tests needing individual isolation. Failure reporting is the weak point. Without per-case detail a batch failure tells you very little. Introduction In today’s competitive environment, ensuring the… Read more »
6 minutes readKey takeaways Contract testing checks that a provider and consumer still agree, without running both together. It catches integration breakage far earlier and far faster than end-to-end tests. The contract has to be generated from real usage, or it documents an API nobody calls. Introduction Imagine two companies entering into a business agreement: each knows… Read more »
