dart-test-fundamentals SKILL.md skillA
dart-test-fundamentals from kevmoo/dash_skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add kevmoo/dash_skills/dart-test-fundamentals@git:20261017.ce6cdbdPins git:20261017.ce6cdbd in mdr.lock. Pin the fingerprint instead.

Core concepts and best practices for `package:test`. Covers `test`, `group`, lifecycle methods (`setUp`, `tearDown`), and configuration (`dart_test.yaml`).
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
# Dart Test Fundamentals
## When to use this skill
Use this skill when:
- Writing new test files.
- Structuring test suites with `group`.
- Configuring test execution via `dart_test.yaml`.
- Understanding test lifecycle methods.
### When NOT to use (Abstention Guardrails)
Do NOT apply this skill or refactor existing tests when:
- **Legacy Single-Group Churn**: Do NOT remove or reformat existing `group`
hierarchies in untouched existing tests unless explicitly asked, as this
causes unwanted diff churn.
- **Alternative Assertion Frameworks**: The package has migrated to
`package:checks` or a specialized testing framework; do not revert tests back
to legacy `package:matcher` idioms.
- **Trivial Tests with Zero Setup**: Simple standalone tests with no shared
state or resources do not need `group`, `setUp`, or `addTearDown`. Do not add
ceremonial wrapper boilerplate.
## Discovery
To find candidates for improving test structure:
### `try-finally` Cleanup
Search for tests that use `try-finally` for cleanup instead of `addTearDown`:
- **Regex**: `\bfinally\s*\{` (Check if this is used for resource cleanup inside
a test).

How to install
mdr add kevmoo/dash_skills/dart-test-fundamentals@sha256:17c6847289cd0b4dThe line at the top of this page pins the label git:20261017.ce6cdbd, 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.
