# 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.
