SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Database bugs can lead to catastrophic data loss or corruption, yet comprehensive database testing is often overlooked or complex to implement. This Skill provides essential patterns for validating schema, data integrity, migrations, and transaction isolation.

Core Features & Use Cases

  • Schema Validation: Automatically verify table structures, column types, and constraints to ensure database design correctness.
  • Data Integrity Checks: Test unique constraints, foreign key relationships, and check constraints to prevent invalid data entries.
  • Migration Testing: Validate forward and backward migrations, ensuring data preservation and reversibility for safe database evolution.
  • Use Case: Before deploying a new feature that modifies your database schema, use this skill to automatically run migration tests, ensuring the new schema is correctly applied, existing data is preserved, and the migration can be safely rolled back if needed.

Quick Start

Write a test to verify that the 'users' table has a unique email constraint and that a foreign key prevents deleting a user with associated orders.

FAQPage Schema
How do I test database schema validation in CI pipelines?

Schema validation tests query information_schema to verify table structures, column types, and constraints automatically. This ensures database design correctness before deployment and catches structural inconsistencies early in CI pipelines without manual inspection.

Can I test data integrity constraints like foreign keys and unique constraints?

Yes, data integrity testing validates unique, foreign key, and check constraints by running targeted queries against your database. This prevents invalid data entries and relationship violations before they reach production.

How do I ensure database migrations are safe and reversible?

Migration testing applies forward and backward migrations while verifying data preservation and rollback capability. This confirms new schemas deploy correctly and existing data survives the transition, enabling safe database evolution.

What's the best way to test ACID transaction properties in relational databases?

Transaction isolation testing uses multi-threaded or concurrent queries to validate ACID properties directly against your database. This confirms transactions maintain consistency and isolation under real concurrency conditions.

How can I identify query performance issues before production?

Query performance testing measures execution time and analyzes explain plans to detect slow or inefficient queries. This catches performance bottlenecks during staging so you avoid costly runtime incidents in production.

Do I need custom test code to validate schema and migrations?

No, this skill provides pre-built patterns for schema validation, data integrity checks, and migration testing that work with standard relational databases. You write focused tests using the provided patterns rather than building validation logic from scratch.
