UPDATE DB Migration test

Database Migration Test Suite Test Case 1: Schema Creation Objective: Verify that the migration creates all required tables with correct schema Test Steps:Run the migration script on a clean database Query the database schema to verify table existence Validate column names, data types, and constraints Expected Result: All tables are created with correct structurePass/Fail Criteria: Schema matches the migration specification exactly

Test Case 2: Data Migration Objective: Ensure existing data is migrated correctly without loss Test Steps:Populate source database with test data Execute migration script Compare row counts between source and target Verify data integrity and relationships Expected Result: All data is transferred accurately with maintained relationshipsPass/Fail Criteria: 100% data accuracy with zero data loss

Test Case 3: Rollback Functionality Objective: Test the ability to rollback migration changes Test Steps:Apply the migration Execute the rollback script Verify database returns to previous state Check data integrity after rollback Expected Result: Database is restored to pre-migration statePass/Fail Criteria: Complete restoration without data corruption

Test Case 4: Index Creation Objective: Validate that all indexes are created properly Test Steps:Run migration script Query database for index information Verify index names, columns, and types Test query performance with indexes Expected Result: All indexes exist and improve query performancePass/Fail Criteria: All specified indexes are present and functional

Test Case 5: Foreign Key Constraints Objective: Ensure foreign key relationships are established correctly Test Steps:Apply migration Attempt to insert data violating foreign key constraints Verify constraint enforcement Test cascading updates and deletes Expected Result: Foreign key constraints are enforced properlyPass/Fail Criteria: Constraint violations are rejected, cascading works as expected

Test Case 6: Migration Idempotency Objective: Verify migration can be run multiple times safely Test Steps:Run migration script once Run the same migration script again Check for errors or duplicate objects Verify data integrity Expected Result: Second run completes without errors or duplicatesPass/Fail Criteria: Migration handles re-execution gracefully

Test Case 7: Performance Testing Objective: Measure migration execution time and resource usage Test Steps:Prepare database with production-like data volume Monitor CPU, memory, and disk I/O during migration Record execution time Compare against performance benchmarks Expected Result: Migration completes within acceptable timeframePass/Fail Criteria: Execution time meets performance requirements

Test Case 8: Default Values Objective: Verify default values are set correctly on columns Test Steps:Run migration Insert rows without specifying default columns Query inserted data to verify defaults Test various default value types Expected Result: Default values are applied automaticallyPass/Fail Criteria: All default values match specification
