Is end-to-end (e2e) testing covered?

Yes, the skill includes best practices for setting up e2e tests to validate the entire application stack from request to response.

Does it handle dependency injection in tests?

Yes, the skill provides guidance on configuring the NestJS TestingModule to correctly inject and override providers, including factory and async providers.

Can I use this for database repository mocking?

Absolutely. It includes patterns for using getRepositoryToken to mock TypeORM repositories without requiring a live database connection.

Does this skill support the Jest framework?

Yes, it is specifically designed to work with Jest, providing implementation patterns for spies, mocks, and assertions common in the NestJS ecosystem.
