golang-testing — Skills — getagentictools

What it does

gotests: go install github.com/cweill/gotests/gotests@latest

Testing concurrent code with time-based operations (time.Sleep, time.After, time.Ticker)

When race conditions need to be reproducible

When tests are flaky due to timing issues

time.Sleep advances synthetic time instantly when the goroutine blocks

time.After fires when synthetic time reaches the duration

All goroutines run to blocking points before time advances

Requirements & configuration

1. Table-driven tests MUST use named subtests -- every test case needs a name field passed to t.Run

When race conditions need to be reproducible

When a test, benchmark, or fuzz target needs to persist files for inspection, use ArtifactDir() instead of ad-hoc paths or repo-local output.

See samber/cc-skills-golang@golang-stretchr-testify skill for detailed testify API (assert, require, mock, suite)

Configuration: GOEXPERIMENT

golang-testing FAQ

What does the golang-testing skill do?

Production-ready Golang tests — table-driven tests, testify suites and mocks, parallel tests, fuzzing, fixtures, goroutine leak detection with goleak, snapshot testing, code coverage, integration tests, idiomatic test naming. Use when writing or reviewing Go tests, choosing a testing approach, setting up Go test CI, or debugging flaky/slow tests. For testify-specific APIs see `samber/cc-skills-golang@golang-stretchr-testify`; for measurement methodology see `samber/cc-skills-golang@golang-benchmark`. gotests: go install github.com/cweill/gotests/gotests@latest Testing concurrent code with time-based operations (time.Sleep, time.After, time.Ticker)
