# Delete tests with their feature

For AI agents: the [site map](https://agentwranglers.se/llms.txt) lists everything here, and this page sits under [Structure](https://agentwranglers.se/playbook/architecture/structure.md).

By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers.md). Updated 2026-10-27.

- ID: ARC-62
- Level: Recommended
- Chapter: [Structure](https://agentwranglers.se/playbook/architecture/structure.md)
- Rule: When you remove a feature, remove its tests, fixtures and settings in the same change.
- Check: The dead code finder covers test folders too. In review, a removal change also deletes the matching tests.
- How: Search for the feature's name across tests, fixtures, settings and docs before you merge. Tests for removed code keep dead helpers alive and slow every run. It is the reverse of [Ship tests in the same change](https://agentwranglers.se/playbook/testing/test-strategy/tests-with-the-change.md).

## Examples

**Using these examples:** they show one way to follow this rule. Keep the behaviour and the check, not the syntax. Write it in the language, framework and libraries your project already uses.

### Plain text example

```text
Removed: src/gift-cards/, tests/gift-cards/, fixtures/gift-cards.json, GIFT_CARDS_ENABLED
```
