About This Skill
What it does
The snapshot-test-helper skill assists with creating and managing snapshot tests. It allows you to generate initial snapshots, diff existing snapshots against changes, and update snapshots when necessary. This simplifies the process of testing UI components or data structures by providing a structured approach to capturing and verifying their state.
When to use it
- Initial Snapshot Creation: When introducing a new component or feature where snapshot tests are desired, this skill can generate an initial baseline snapshot.
- Regression Testing: To ensure that changes haven't unintentionally broken existing UI elements or data structures, compare current states against previous snapshots.
- Snapshot Updates: When intentional modifications require updating the stored snapshot to reflect the new expected state.
- Automated Test Suites: Integrate into automated testing pipelines to regularly verify UI consistency and prevent regressions.
Key capabilities
- Generate initial snapshots
- Diff existing snapshots against current states
- Update snapshots with changes
Example prompts
- "Create a snapshot for the 'user profile' component."
- "Show me the diff between the current state of the 'product listing' and its last snapshot."
- "Update the snapshot for the 'shopping cart' after these modifications."
Tips & gotchas
- Requires familiarity with snapshot testing concepts.
- Ensure that any dynamic data or content is properly seeded before generating snapshots to ensure consistent results.
