Testing Rules

Ensure proper test coverage and quality.

---

Rules Overview

Rule	Label	Purpose
test-only-change	test-only-change	Only test files modified
test-missing	test-missing	Code changed without tests
test-improvement	test-improvement	Tests improved with code

---

test-missing

Most Important: Flags when source code changes without corresponding test changes.

Detection

• Source files changed (.js, .ts, .py, etc.)
• No test files changed (.test.js, .spec.ts, _test.py, etc.)

Example

enabled_rules: '["test-missing"]'

Changed Files:

src/utils/calculator.ts  ← Source code

Result: 🔴 test-missing label applied

---

test-only-change

Fast-track PRs that only modify tests.

Example

Changed Files:

src/__tests__/calculator.test.ts
tests/integration/api.test.ts

Result: 🟢 test-only-change label (fast-track eligible)

---

test-improvement

Acknowledges when tests are added/improved with code changes.

Example

Changed Files:

src/utils/calculator.ts
src/__tests__/calculator.test.ts

Result: 🟡 test-improvement label (good practice!)
