Enforce native parameterized or table-driven tests when adding or modifying unit tests that exercise the same behavior with multiple data cases. Use whenever unit tests add repeated cases, edge-case matrices, or duplicated setup, execution, and assertions that differ only by case data.

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

# Parameterized Tests

Use data-driven tests whenever multiple unit-test cases exercise the same behavior with the same test logic.

## Core Rule

When adding or modifying unit tests, if two or more cases share the same setup, execution, and assertion semantics and differ only in inputs, expected outputs, expected errors, options, or equivalent case data, express them with the test framework's native parameterization mechanism.

If a new case would duplicate an existing standalone test with the same test logic, consolidate the touched group instead of adding another duplicated test.

## Workflow

1. Inspect nearby tests and repository guidance to identify the testing framework and established idioms.
2. Identify cases that share setup, execution, and assertion semantics.
3. Parameterize groups of two or more equivalent cases with the framework's native mechanism.
4. Keep each case independently identifiable in test output when the framework supports case names or IDs.
5. Prefer explicit case data over branching inside the shared test body.
6. Run the narrowest relevant test command after the change.

How to install

The exact contents, by fingerprint
mdr add dceoy/ai-coding-agent-skills/parameterized-tests@sha256:dfc9b0817ad4e89c

The line at the top of this page pins the label git:20260816.9eb84f0, 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.
