SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Validates endpoints and repositories that touch PostgreSQL by running integration tests against a real database, ensuring test isolation and reliable side-effect verification.

Core Features & Use Cases

  • End-to-end database testing: Validate that HTTP endpoints and data access layers correctly interact with PostgreSQL, including transactions, triggers, and constraints.
  • Isolated test executions: Ensure tests do not cross-contaminate through transactional scope management and per-suite isolation strategies.
  • Deterministic teardown: Guarantee cleanup after test runs to keep environments clean.

Quick Start

Run the test suite after configuring the environment.

FAQPage Schema
How do I run integration tests against a real PostgreSQL database using Jest?

Integration tests against a real PostgreSQL database run by configuring a separate .env.test, executing database migrations before the test suite, and performing deterministic teardown after tests to ensure isolation and verify side effects.

What's the best way to isolate Supertest HTTP endpoint tests that modify SQL data?

Isolating Supertest endpoint tests that modify SQL data requires transactional scope management and per-suite isolation strategies, ensuring tests do not cross-contaminate while validating interactions with database transactions, triggers, and constraints.

Do I need a separate test environment configuration for PostgreSQL integration testing?

A separate .env.test configuration is required for PostgreSQL integration testing to isolate the test database environment, allowing migrations to run cleanly before tests and ensuring teardown procedures do not affect production data.

How does teardown work after a Jest test suite touches PostgreSQL?

Teardown after a Jest test suite touches PostgreSQL by executing deterministic cleanup procedures that remove test-generated records and reset database state, guaranteeing environments remain clean and preventing side-effect contamination between runs.

Can I verify database constraints and triggers during end-to-end HTTP testing?

End-to-end HTTP testing with Supertest validates database constraints and triggers by exercising real PostgreSQL interactions through HTTP endpoints and data access layers, ensuring persistence logic and side-effect verification function correctly under integration conditions.
