testing-reef

testing-reef is a Test authoring & frameworks skill for AI agents, published by Blushyes in the reef repository on GitHub. Skillspace rates testing-reef C (74/100) and it passed the safety scan; the rating is based on static analysis only.

Conventions and gotchas for writing tests in the reef Rust workspace — unit, integration, property, snapshot, benchmark, and fuzz. Use whenever adding or modifying a test in reef or test-support, or when the user asks "add a test for X", "how should I test Y", "why is this test flaky", "where does this test go", or anything about test fixtures, snapshots, proptest, or CI test failures. Also use when touching clock/time code (requires splitting `*_at(now, t)` helpers), or any code that mutates `cwd`/`HOME` (needs process-wide lock). Covers file-placement rules, the `test-support` fixture crate, insta filters, proptest strategy construction, and the specific pitfalls we've paid for in production — macOS tempdir symlinks, env-var sharing across parallel tests, and the HOME-redirect pattern for prefs-reading code.
