test-strategy SKILL.md skillA

test-strategy from aethrox/doctrine is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

mdr add aethrox/doctrine/test-strategy@git:20260809.2a45dbb

Pins git:20260809.2a45dbb in mdr.lock. Pin the fingerprint instead.

Suite-level testing decisions that sit above individual tests, where test data comes from (synthetic factories vs anonymized production snapshots), the flaky-test quarantine policy, and where the integration/e2e boundary actually belongs. Use when deciding how a test suite should source its data, what to do with a flaky test, or whether a given seam needs a full integration test, a contract test, or a unit test with a double is enough. Does not cover the red-green-refactor cycle or test-double…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Test Strategy

Where a test gets its data from and what happens when it goes flaky are suite-level policies, decided once and applied consistently, not improvised per test or per failure. This skill covers the decisions that sit above the individual red-green-refactor cycle (see `tdd` for that): test data sourcing, flaky-test handling, and the integration/e2e boundary.

## Phase 1: Test data

Default to **synthetic data generated at test runtime**: factories or fixtures that build exactly the shape a test needs, checked into the test itself or a shared factory module. This is fast, requires no external data source, and its content is fully under the test's control (see `tdd` Phase 2, expected values need an independent source of truth, and hand-built synthetic data is that source).

Reach for a **production data snapshot** only when synthetic data genuinely can't reproduce the bug pattern or edge case under test; real-world data has irregularities and relationship patterns synthetic generators tend to smooth over. When a snapshot is used:

How to install

The exact contents, by fingerprint

mdr add aethrox/doctrine/test-strategy@sha256:4fca1b617735a13a

The line at the top of this page pins the label git:20260809.2a45dbb, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
