name	gen-test
description	Generate Vitest tests for a file following project conventions. Use when asked to create tests for a source file.
disable-model-invocation	true

Generate tests for: $ARGUMENTS

Test Stack

• Runner: Vitest (vitest run)
• React: @testing-library/react with @testing-library/user-event
• Assertions: @testing-library/jest-dom for DOM matchers, Vitest expect for everything else
• Mocking: vi.mock() for modules, vi.fn() for functions

Conventions

1. Read the existing test at app/api/queue/items/route.test.ts for the project's testing patterns
2. Read the source file specified in $ARGUMENTS
3. Place the test file adjacent to the source: <filename>.test.ts or <filename>.test.tsx
4. Use describe blocks grouped by function/component, with it for individual cases
5. Mock Supabase client when testing code that uses @supabase/supabase-js or @supabase/ssr
6. Mock process.env in beforeEach, restore in afterEach
7. For React components: test user interactions, rendered output, and edge cases
8. For API routes: test request validation, success paths, and error handling
9. For utility functions: test happy paths, edge cases, and error conditions

After Generation

Run the tests to verify they pass:

npx vitest run --reporter=verbose <test-file-path>

Fix any failures before finishing.
