Find duplicate, overlapping, tautological, dead, and low-value tests in.
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
Find duplicate, overlapping, tautological, dead, and low-value tests in the project's test suite. Read-only static analysis — does not modify any files or execute the test suite. ## Arguments - `$ARGUMENTS` — optional: specific test file or directory (default: full suite) ## Setup Read `.rdf/governance/index.md` to identify: - Test framework (BATS, pytest, jest, etc.) - Test directory location - Test conventions from governance/verification.md ## Definitions **Duplicate** — two test blocks with identical descriptions, or same target + same inputs + same assertion with only a cosmetically different name. **Overlapping** — 3+ tests exercise the same code path with the same input class. The excess tests can be removed without loss of coverage. **Tautological / Noop** — assertion that cannot fail given the test setup: - Only assertion is success-check on a command that succeeds unconditionally - Test asserts something the test itself just set up - Expected value constructed identically to the actual **Dead** — permanently unreachable: - Unconditional skip with no guard condition - Skip with "TODO"/"not implemented" and no issue tracker reference …

How to install
mdr add rfxn/rdf/r-util-test-dedup@sha256:2769cf784ef530b6The line at the top of this page pins the label git:20260902.42a192d, 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.
