nw-test-refactoring-catalog from nwave-ai/nwave is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nwave-ai/nwave/nw-test-refactoring-catalog@git:20260320.d98f3cbPins git:20260320.d98f3cb in mdr.lock. Pin the fingerprint instead.

Detailed refactoring mechanics with step-by-step procedures, and test code smell catalog with detection patterns and before/after examples.
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 Refactoring Catalog
## Test Code Smells (Full Detail)
### L1 Readability Smells
#### Obscure Test
- **Problem**: test name does not reveal business scenario being tested
- **Detection**: generic names like Test1(), ProcessOrderTest(), or names requiring reading test body to understand
- **Solution**: rename to Given_When_Then or should_do_expected_thing_when_condition format
```
Before: public void Test1() { /* ... */ }
After: public void ProcessOrder_PremiumCustomer_AppliesCorrectDiscount() { /* ... */ }
```
#### Hard-Coded Test Data
- **Problem**: magic numbers and strings obscure business rules being tested
- **Detection**: numbers like 1000, 0.15, strings without explanation
- **Solution**: extract to named constants that reveal business meaning
```
Before: Assert.Equal(850, result.Total); // What discount?
After: const decimal EXPECTED_TOTAL = 1000 * (1 - 0.15m);
Assert.Equal(EXPECTED_TOTAL, result.Total);
```
#### Assertion Roulette
- **Problem**: multiple assertions without messages make failures unclear
- **Detection**: multiple Assert.* calls without message parameter

How to install
mdr add nwave-ai/nwave/nw-test-refactoring-catalog@sha256:af11cad1d79d652cThe line at the top of this page pins the label git:20260320.d98f3cb, 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.
