nextship-loadtest takes an address and reports how many users at once the site holds. It writes the k6 script, runs k6 from PATH or from the official Docker image, and reads the summary back: up to five rising steps, each held when at most 1% of its requests fail and 95% finish within a second. It prints its plan and sends nothing until --yes, and a target that never answers is an error rather than a result. In its own package with no dependency on the CLI, so it can be used without nextship. Not published. 39 unit tests, and an end-to-end script that passes with k6 2.3.0 on PATH and that CI runs with Docker and with k6 on PATH.
scripts/e2e.mjs docker passes with Docker Desktop (Docker 29.7.2) on Windows, with the server on the same machine requested as host.docker.internal. macOS is the one path still not run.
