| planning-oracle-to-postgres-migration-integration-testing | 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
- Coverage mapping that ensures every database touchpoint has at least one test case (or a justified set of cases for high-risk methods)
When defining recommended test cases, explicitly include:
- Text parameter behavior for both empty string and
NULL/missing values. - Datetime/timezone assertions, including round-trip and comparison behavior.
- Cases where destination columns use
timestamp without time zoneortimestamp(0), with explicit timezone-application expectations.
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.
