4 minutes readKey takeaways A plain uptime ping is not enough: an MCP server can answer while its tools are broken. Monitor a real tool call and assert on the response, not just the transport. Alert on auth failures separately, since a stranded key looks like a healthy server. MCP servers have quietly become production infrastructure. If… Read more »
5 minutes readKey takeaways Self-hosted k6 is cheapest until you need distribution, which is where the operational cost starts. Managed options mostly sell orchestration and retention rather than a faster engine. Decide by how often you run at scale, not by peak virtual users. k6 is free and open source, and on your laptop it is a… Read more »
13 minutes readKey takeaways AI mainly changes test design: generating realistic scenarios instead of you hand-writing them. Adaptive tests adjust load during the run, which surfaces breaking points a fixed ramp misses. It does not remove the need to decide what good looks like. Thresholds remain a human judgement. AI Reshapes Automated Load Testing: What’s Different in… Read more »
18 minutes readKey takeaways An SPA does its work after the initial HTML, so HTTP-level tests miss most of it. Test the API calls the app makes, weighted the way the app makes them. Add a small browser-level test for render timing, since the two measure different things. SPA Load Testing: Why Traditional Methods Fall Short –… Read more »
7 minutes readKey takeaways A virtual user simulates one person's session, including its pauses and sequence. Virtual users are not requests per second; the relationship depends on think time. Model think time honestly, since removing it invents traffic nobody generates. Virtual users (VUs) are the simulated humans that hit your system during a load test. They’re the… Read more »
7 minutes readKey takeaways Load testing checks behaviour at expected demand; stress testing finds where it breaks. Run load tests regularly and stress tests before capacity decisions. Stress testing is only useful if you watch how the system recovers afterwards. Load testing and stress testing are not the same thing, even though the terms get thrown around… Read more »
18 minutes readKey takeaways Testing has shifted from a release gate to a continuous signal, which changes how teams are staffed. Cloud capacity removed the scale constraint, so the limit is now scenario quality. For a CTO the decision is where testing sits in the pipeline, not which vendor to buy. Introduction: Why Cloud Testing Disrupted the… Read more »
