```
**Step 1: Inspect the target project**
Read the target project's `.csproj` to determine the .NET version and existing package references. Match these versions exactly — do not upgrade.
**Step 2: Create the xUnit test project**
Target the same .NET version as the application under test.
Add NuGet packages for Oracle database connectivity and xUnit.
Add a project reference to the target project only — no other application projects.
Add an `appsettings.json` configured for Oracle database connectivity.
**Step 3: Implement transaction-rollback base class**
Create a base test class that opens a transaction before each test and rolls it back after.
Catch and handle all exceptions to guarantee rollback.
Make the pattern inheritable by all downstream test classes.
**Step 4: Implement seed data manager**
Create a global seed manager for loading test data within the transaction scope.
Do not commit seed data — transactions roll back after each test.
Do not use `TRUNCATE TABLE` — preserve existing database data.
Reuse existing seed files if available.
Establish a naming convention for seed file location that downstream test creation will follow.
**Step 5: Verify the project compiles**
Build the test project and confirm it compiles with zero errors before finishing.
