test-generator

To generate deterministic Rust integration tests, this Skill creates golden fixture directories under tests/fixtures/ and auto-generates matching integration tests in crates/dirctl-core/tests/ that load fixtures, run the pipeline, and compare Plan JSON outputs for stable regression testing.

Snapshot-driven regression testing for Rust planners and scanners involves creating deterministic golden fixtures that capture expected outputs, enabling reproducible diffs across builds. This Skill generates those fixtures and corresponding tests to ensure scanner and executor components produce stable, comparable Plan JSON results.

Yes, you can use deterministic timestamps to ensure reproducible test diffs across builds in Rust. This Skill applies test helpers that inject fixed timestamps into generated golden fixtures, guaranteeing that integration tests for dirctl planner and executor components yield consistent snapshot comparisons.

Setting up golden fixtures for Rust integration tests involves creating snapshot data under tests/fixtures/<name>/ and generating corresponding tests that execute the dirctl pipeline. This Skill automates that scaffolding, producing tests that load fixtures and compare Plan JSON outputs for regression validation.

Yes, this test-generation approach works for dirctl planner, scanner, and executor components. The Skill specifically targets the core dirctl engine components, generating deterministic golden fixtures and integration tests that validate the pipeline's Plan JSON outputs across all three component stages.

A limitation of using golden fixtures for Rust regression testing is that any intentional change to dirctl planner or scanner logic requires regenerating the fixture snapshots. This approach verifies deterministic Plan JSON output against static data rather than testing dynamic or time-sensitive behaviors.
