# Database Test Helper

## Overview

This skill provides automated assistance for database test helper tasks within the Test Automation domain.

## When to Use

This skill activates automatically when you:
- Mention "database test helper" in your request
- Ask about database test helper patterns or best practices
- Need help with test automation skills covering unit testing, integration testing, mocking, and test framework configuration.

## Instructions

Overview

This skill assists engineers with database test helper operations inside Test Automation workflows. It provides step-by-step guidance, generates production-ready test code and configurations, and validates outputs against common standards. Use it to streamline unit, integration, and mock-driven database testing.

How this skill works

The skill inspects test requirements and environment context, then recommends patterns, fixtures, and helper utilities tailored to your stack (e.g., pytest, Jest, or custom frameworks). It generates code snippets for setup/teardown, transaction management, seeding, and mocks, and offers configuration files for CI and local development. It also checks generated artifacts against best-practice rules and common error cases.

When to use it

  • Writing unit or integration tests that interact with a database
  • Creating reusable test helpers for setup, teardown, and seeding
  • Converting ad-hoc database code into deterministic tests
  • Configuring CI pipelines to run database-backed test suites
  • Troubleshooting flaky tests caused by shared state or transactions

Best practices

  • Isolate tests with ephemeral databases or transactional rollbacks
  • Seed only required data and prefer factories over large fixtures
  • Mock external dependencies; keep DB helpers focused on data state
  • Use deterministic ordering and explicit cleanup to avoid flakiness
  • Store environment-specific configs separately and secure credentials

Example use cases

  • Generate a pytest fixture that spins up a temporary PostgreSQL container, applies migrations, and tears down after tests
  • Create a Jest setup file that seeds an in-memory database and resets state between tests
  • Produce helper functions for transactional tests that auto-rollback on failure
  • Translate a legacy integration test into a robust, isolated test using factories and mocks
  • Write CI config snippets that prepare database services and run migration steps before test execution

FAQ

What stacks does this helper support?

It provides patterns usable across common stacks (Python/pytest, Node/Jest, Dockerized DBs) and can be adapted to others by changing migrations and connection hooks.

How does it reduce flaky tests?

By promoting isolation strategies—transaction rollbacks, ephemeral databases, deterministic seeding—and validating teardown and cleanup steps automatically.
