Testing & Quality
View on GitHub

Creates an integration testing plan for .NET data access artifacts during Oracle-to-PostgreSQL database migrations. Analyzes a single project to identify repositories, DAOs, and service layers that interact with the database, then produces a structured testing plan. Use when planning integration test coverage for a migrated project, identifying which data access methods need tests, or preparing for Oracle-to-PostgreSQL migration validation.

Planning Integration Testing for Oracle-to-PostgreSQL Migration

Analyze a single target project to identify data access artifacts that require integration testing, then produce a structured, actionable testing plan.

Workflow

Progress:
- [ ] Step 1: Identify data access artifacts
- [ ] Step 2: Classify testing priorities
- [ ] Step 3: Write the testing plan

Step 1: Identify data access artifacts

Scope to the target project only. Find classes and methods that interact directly with the database — repositories, DAOs, stored procedure callers, service layers performing CRUD operations.

Step 2: Classify testing priorities

Rank artifacts by migration risk. Prioritize methods that use Oracle-specific features (refcursors, TO_CHAR, implicit type coercion, NO_DATA_FOUND) over simple CRUD.

Step 3: Write the testing plan

Write a markdown plan covering:

  • List of testable artifacts with method signatures
  • Recommended test cases per artifact
  • Seed data requirements
  • Known Oracle→PostgreSQL behavioral differences to validate

Output

Write the plan to: .github/oracle-to-postgres-migration/Reports/{TARGET_PROJECT} Integration Testing Plan.md

Key Constraints

  • Single project scope — only plan tests for artifacts within the target project.
  • Database interactions only — skip business logic that does not touch the database.
  • Oracle is the golden source — tests should capture Oracle's expected behavior for comparison against PostgreSQL.
  • No multi-connection harnessing — migrated applications are copied and renamed (e.g., MyApp.Postgres), so each instance targets one database.
