Improve Jest Tests with Proven Patterns
Jest tests often become brittle when data, mocks, and assertions are inconsistent. This skill provides practical patterns for TDD, factories, mocking, and behavior-focused tests.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "testing-patterns" from https://skillstore.io/skills/sickn33-testing-patterns.md and its manifest at https://skillstore.io/api/skills/sickn33-testing-patterns/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "testing-patterns". A component needs tests for default rendering and a button press.
Expected outcome:
A focused test plan with a custom render helper, default props factory, visible text assertion, and interaction assertion.
Using "testing-patterns". A GraphQL-backed screen needs loading, empty, and success coverage.
Expected outcome:
A mock strategy for the generated hook plus separate test cases for each user-visible state.
Using "testing-patterns". A test file repeats user objects with inconsistent fields.
Expected outcome:
A reusable user factory with default fields and examples for overriding only the fields under test.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Write Component Unit Tests
Create behavior-focused tests for rendering, loading states, edge cases, and user actions.
Standardize Test Data Setup
Replace repeated object literals with factory functions that provide defaults and clear overrides.
Mock Generated Data Hooks
Mock modules and GraphQL hooks so tests can cover success, empty, loading, and error states.
Try These Prompts
Use testing-patterns to write a Jest test for this React Native component. Focus on visible behavior and use Testing Library queries.
Use testing-patterns to create a reusable props factory for this component. Include sensible defaults and override support.
Use testing-patterns to mock this generated GraphQL hook. Add tests for loading, empty, error, and success states.
Use testing-patterns to review this Jest test file. Replace implementation-detail assertions with behavior checks and extract factories where useful.
Best Practices
- Write the failing test first, then add only the production code needed to pass.
- Use factory functions for props and data so tests stay consistent and easy to update.
- Assert public behavior through visible output and user interactions.
Avoid
- Do not test implementation details that users cannot observe.
- Do not assert only that a mock function was called when real behavior can be checked.
- Do not duplicate large test data objects across many test cases.
