Project history and usage

vgt is a small Go developer tool for turning `go test -json` output into a browser visualization. Its niche is test-suite diagnosis: it helps Go developers see test parallelism, slow tests, and the actual schedule produced by the Go test runner.

Project history

The public GitHub repository was created on 2024-09-21 by Robert Laszczak. The project was introduced alongside a Three Dots Labs article about why adding CPU cores alone does not necessarily speed up Go test suites, and the README describes vgt as a tool for visualising Go test results in a browser.

How it is used

The typical workflow is deliberately Unix-like: run `go test -json ./...` and pipe the event stream into `vgt`, or save the JSON output and replay it later. vgt then opens a browser view of the test run, with flags for reading from a file, printing HTML, preserving browser state, and filtering very short durations.

Why package nerds care

vgt is significant mainly as a focused companion to Go's standard JSON test output. Instead of replacing `go test`, it consumes the standard event stream and makes timing and parallelism visible, which is useful when tuning `t.Parallel`, package-level concurrency, and slow integration-test suites.
