  feature: podcast-tui-app
  priority: P1
  depends_on: [53]
  tags: [testing, framework, setup, opentui]

objective:
- Set up OpenTUI testing framework
- Configure test runner
- Set up snapshot testing
- Configure test environment

deliverables:
- `tests/` directory with test structure
- `tests/setup.ts` with test setup
- `tests/config.ts` with test configuration
- `package.json` with test scripts

steps:
- Install testing dependencies:
  - `@opentui/testing`
  - `@opentui/react` (for testing)
  - `@opentui/solid` (for testing)
  - `bun test` (built-in test runner)
- Configure test environment:
  - Set up test renderer
  - Configure test options
  - Set up test fixtures
- Create test structure:
  - `tests/components/` for component tests
  - `tests/integration/` for integration tests
  - `tests/utils/` for utility tests
  - `tests/fixtures/` for test data
- Add test scripts to `package.json`:
  - `test`: Run all tests
  - `test:watch`: Run tests in watch mode
  - `test:coverage`: Run tests with coverage
  - `test:components`: Run component tests
  - `test:integration`: Run integration tests

tests:
- Unit: Verify testing framework is set up
- Integration: Verify test scripts work
- Component: Verify snapshot testing works

acceptance_criteria:
- Testing framework installed and configured
- Test scripts work correctly
- Snapshot testing configured
- Test environment set up

validation:
- Run `bun test` to execute all tests
- Run `bun test:components` to run component tests
- Run `bun test:coverage` for coverage report
- Check all tests pass

notes:
- Use OpenTUI's testing framework for snapshot testing
- Test components in isolation
- Use test fixtures for common data
- Mock external dependencies
- Keep tests fast and focused
- Add CI/CD integration for automated testing
