Scaffolding Oracle To Postgres Migration Test Project

1---2name: scaffolding-oracle-to-postgres-migration-test-project3description: 'Scaffolds an xUnit integration test project for validating Oracle-to-PostgreSQL database migration behavior in .NET solutions. Creates the test project, transaction-rollback base class, and seed data manager. Use when setting up test infrastructure before writing migration integration tests, or when a test project is needed for Oracle-to-PostgreSQL validation.'4---5 6# Scaffolding an Integration Test Project for Oracle-to-PostgreSQL Migration7 8Creates a compilable, empty xUnit test project with transaction management and seed data infrastructure for a single target project. Run once per project before writing tests.9 10## Workflow11 12```13Progress:14- [ ] Step 1: Inspect the target project15- [ ] Step 2: Create the xUnit test project16- [ ] Step 3: Implement transaction-rollback base class17- [ ] Step 4: Implement seed data manager18- [ ] Step 5: Verify the project compiles19```20 21**Step 1: Inspect the target project**22 23Read the target project's `.csproj` to determine the .NET version and existing package references. Match these versions exactly — do not upgrade.24 25**Step 2: Create the xUnit test project**26 27- Target the same .NET version as the application under test.28- Add NuGet packages for Oracle database connectivity and xUnit.29- Add a project reference to the target project only — no other application projects.30- Add an `appsettings.json` configured for Oracle database connectivity.31 32**Step 3: Implement transaction-rollback base class**33 34- Create a base test class that opens a transaction before each test and rolls it back after.35- Catch and handle all exceptions to guarantee rollback.36- Make the pattern inheritable by all downstream test classes.37 38**Step 4: Implement seed data manager**39 40- Create a global seed manager for loading test data within the transaction scope.41- Do not commit seed data — transactions roll back after each test.42- Do not use `TRUNCATE TABLE` — preserve existing database data.43- Reuse existing seed files if available.44- Establish a naming convention for seed file location that downstream test creation will follow.45 46**Step 5: Verify the project compiles**47 48Build the test project and confirm it compiles with zero errors before finishing.49 50## Key Constraints51 52- Oracle is the golden behavior source — scaffold for Oracle first.53- Keep to existing .NET and C# versions; do not introduce newer language or runtime features.54- Output is an empty test project with infrastructure only — no test cases.
