Question

A backend developer is asked to add integration tests for a REST endpoint that reads and writes to a PostgreSQL database. They want Copilot Chat to generate tests that exercise the real persistence layer rather than mocked repositories. Which approach will most reliably produce useful integration tests with Copilot?

Accepted Answer

Open the endpoint controller, repository, and any existing test-container/database setup files, then prompt Copilot to generate tests that spin up a test database, seed fixtures, and assert on persisted state

Answer

Ask Copilot in an empty test file to 'write integration tests for the user endpoint' without opening any related source or configuration files

Answer

Prompt Copilot to mock the repository layer and return canned objects so the tests never touch a real database

Answer

Ask Copilot to generate the tests and trust that they exercise the persistence layer correctly without running them
