Unit Tests: Execute unit tests for individual components: Ensure all unit tests pass to verify the functionality of isolated components.
yarn test
or
npm run test
End-to-End (e2e) Tests: Perform comprehensive tests across the entire GraphQL API:
yarn test:e2e
or
npm run test:e2e
This will run integration tests using Apollo Server integration testing and Supertest to validate API endpoints and interactions.
