Stabilize a flaky test with a minimal, assertion-preserving fix — never by weakening or deleting the check.
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
# Deflake a flaky test A `deflake:` issue names ONE test that has been observed failing and then passing on a rerun of the same commit — the definitive flaky signature. Your job is to make that test deterministic **without changing what it verifies**. The issue body carries the test identity (file + name) and the observed failure signature (e.g. `Test timed out in 5000ms`, `Timed out waiting for …`, an order-dependent assertion, a wall-clock/random-dependent value). Read the test, reproduce the mechanism in your head, and apply the SMALLEST fix from the allowed set below that removes the nondeterminism. ## The only allowed fixes 1. **Raise a timeout / poll budget.** A test that blows vitest's default under CI contention (fully-mocked or I/O-bound, not a perf test) gets a generous per-test `testTimeout` (3rd arg to `it`), or its internal poll loop is given a real wall-clock budget instead of a fixed iteration count (a fixed count of `setImmediate` turns elapses in milliseconds and races real I/O). 2. **Stabilize timing / waiting.** Replace a bare `setTimeout`/fixed `sleep` with an explicit `await` of the real condition (`vi.waitFor`, a resolved …

How to install
mdr add qwenlm/qwen-code/deflake@sha256:f2aba9cc5a37fe78The line at the top of this page pins the label git:20260719.0764276, 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.
