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
