database-testing

Database migration testing validates that schema changes apply correctly, remain reversible, and preserve existing data. Run migration tests in a staging environment to verify forward and rollback scripts work as expected before production deployment.

Data integrity testing enforces unique keys, foreign key relationships, and check constraints to prevent invalid or orphaned records. Validate these constraints regularly to catch violations early and maintain consistency across development, staging, and production.

Schema validation checks that tables, columns, and constraints match your intended design and are properly enforced at the database level. This prevents schema drift and catches configuration errors that could cause application failures.

Yes, query performance measurement is integrated into database testing to identify slow queries and indexing issues. Measure performance metrics during schema verification to catch bottlenecks before they impact production workloads.

Schema verification across development, staging, and production catches discrepancies that cause unexpected behavior. Regular schema validation ensures all environments maintain the same table structure, constraints, and data types.
