Create Reliable Vitest Test Patterns
Teams need consistent tests for TypeScript services, agents, and API routes. This skill provides Vitest patterns with Supabase mocks and clear pass-rate expectations.
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/cleanexpo-testing-patterns.md and its manifest at https://skillstore.io/api/skills/cleanexpo-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.
Agent-readable resources
Use these links when an AI agent, crawler, or script needs clean context instead of reading the full page.
Test it
Using "testing-patterns". Request a unit test pattern for a service method that processes input and rejects invalid values.
Expected outcome:
A concise test outline with setup steps, a successful processing case, and an error assertion for invalid input.
Using "testing-patterns". Request guidance for testing an agent that reads tasks through Supabase.
Expected outcome:
A mock plan that replaces the Supabase client, returns controlled data, and verifies the agent result.
Using "testing-patterns". Request an API route test for missing required parameters.
Expected outcome:
A route test plan that builds a local request, calls the handler, and checks the expected status and error message.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Standardize Feature Tests
Apply a shared Vitest structure when adding service tests for new TypeScript features.
Mock Supabase Workflows
Build predictable tests for agents and database-facing code without calling a live Supabase project.
Verify API Error Handling
Use API route test patterns to check required parameters, status codes, and response error messages.
Try These Prompts
Use the testing-patterns skill to outline a Vitest unit test for my TypeScript service. Include setup, one success case, and one error case.
Use the testing-patterns skill to design a Vitest test for code that reads from Supabase. Show the mock behavior I should configure.
Use the testing-patterns skill to plan tests for a Next.js API route that requires workspace_id and returns validation errors.
Use the testing-patterns skill to review my current test plan. Identify missing unit, integration, agent, and end-to-end coverage areas.
Best Practices
- Clear mocks before each test so earlier assertions do not affect later cases.
- Assert both successful behavior and expected error handling paths.
- Keep Supabase calls mocked unless a test is explicitly an integration test.
Avoid
- Do not call a live Supabase project from ordinary unit tests.
- Do not rely only on a success case when the code validates required input.
- Do not leave placeholder imports or route names unchanged in real tests.
