Guide for writing expressive, behavior-focused tests following Vladimir Khorikov's testing principles. Apply when writing, reviewing, or renaming any test (unit, integration, e2e) in any programming language. Triggers: writing tests, creating test files, adding test cases, reviewing test names, 'test naming', 'rename tests', 'Khorikov', or any test creation task. Covers: naming conventions (plain English over rigid policies), what to test (behavior not implementation), testing styles…
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 Namer Write tests that describe **behavior in plain English**, not implementation details. Based on Vladimir Khorikov's testing principles. ## Naming Guidelines ### Rules 1. **No rigid naming policy** — never use `[MethodUnderTest]_[Scenario]_[ExpectedResult]` or similar templates 2. **Describe behavior to a non-programmer** familiar with the problem domain — a domain expert should understand the test name 3. **Separate words with underscores** in function/method names (not needed in string-based test names like JS/TS) 4. **Do not include the SUT's method name** in the test name — test behavior, not a method 5. **Use plain facts, not wishes** — write `is_invalid`, not `should_be_invalid` 6. **Use basic English grammar** — articles (`a`, `the`) improve readability 7. **Be specific** — `Delivery_with_a_past_date_is_invalid` beats `Delivery_with_invalid_date_is_invalid` ### Naming Progression Example Starting from a rigid convention — progressively improve: ``` IsDeliveryValid_InvalidDate_ReturnsFalse -- rigid, cryptic Delivery_with_invalid_date_should_be_invalid -- plain English (good start) Delivery_with_past_date_should_be_invalid -- more specific …

How to install
mdr add mryll/skills/test-namer@sha256:67e25adad2c60680The line at the top of this page pins the label v1.0.1, 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.
