Write Better Jest Tests With Reusable Patterns

Unit tests often become fragile when they duplicate setup or test implementation details. This skill gives reusable Jest patterns for factories, mocks, render helpers, and TDD.

Agent request
Review the Skillstore skill "testing-patterns" from https://skillstore.io/skills/chriswiles-testing-patterns.md and its manifest at https://skillstore.io/api/skills/chriswiles-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 user asks for a test for a React Native component with theme context.

Expected outcome:

  • A test plan that starts with visible behavior.
  • A render helper recommendation for the theme provider.
  • Focused assertions using Testing Library queries.

Using "testing-patterns". A user has repeated mock user objects across many tests.

Expected outcome:

  • A reusable factory approach with default values and overrides.
  • Guidance to keep test data complete and consistent.
  • Examples of clearer test setup naming.

Using "testing-patterns". A user needs to mock a GraphQL hook response.

Expected outcome:

  • A Jest mocking approach for the generated hook.
  • Separate response states for success, loading, and error cases.
  • A reminder to assert UI behavior instead of mock internals.

What You Can Build

Create Consistent Component Tests

Use render helpers, factories, and Testing Library queries to write maintainable component tests.

Introduce TDD Workflow

Guide a team through failing tests, minimal implementation, and focused refactoring.

Standardize Mocking Practices

Apply clear Jest module and hook mocks without testing mock internals.

Try These Prompts

Start a Simple Unit Test 
Use the testing-patterns skill to write a Jest test for this component. Focus on behavior and use a simple render helper.
Add a Test Factory 
Use the testing-patterns skill to create a factory for these props or data. Include sensible defaults and override support.
Mock a Generated Hook 
Use the testing-patterns skill to mock this generated hook in Jest. Keep the test focused on visible behavior.
Plan a TDD Refactor 
Use the testing-patterns skill to design a red-green-refactor plan for this change. Include tests for normal, loading, empty, and error states.

Best Practices

  • Start with a failing test that describes user-visible behavior.
  • Use factories for props and data so tests stay consistent.
  • Clear mocks between tests and keep each test focused on one behavior.

Avoid

  • Testing implementation details instead of public behavior.
  • Duplicating incomplete mock objects across test files.
  • Asserting that mocks were called when visible behavior is what matters.

Frequently Asked Questions

What frameworks does this skill focus on?
It focuses on Jest, React Native Testing Library, and TypeScript-style component tests.
