k6 load tests with thresholds that pass or fail a run, not charts to interpret.
“We think it will hold. It held last Black Friday and traffic is only up maybe 30%?”
What the wait costs
Capacity planning by optimism, validated in production during the hour that matters most.
Load testing usually fails on setup cost rather than on willingness. Fenwave runs k6 against a chosen component and environment, keeps the run history, and evaluates thresholds you define — p95 latency, error rate — so a run reports pass or fail rather than producing a graph that needs an expert. Point it at a branch environment and you can load test a change before it merges.
How it works
- 01Choose the target component and environment.
- 02Set thresholds — p95 latency, error rate, requests per second.
- 03Run; results are recorded against the run history.
- 04A run that breaches a threshold is marked failed, not left to interpretation.
