What is this?
Integration tests run real ADO.NET against LocalDB/Testcontainers SQL.
Why should you care?
ShopNest procs and constraints only prove themselves on a real engine.
See it live — copy this example
Use a .NET console or API project with SQL Server LocalDB. Run dotnet run after pasting.
// Testcontainers or LocalDB
await repo.InsertAsync(order, ct);
var got = await repo.GetByIdAsync(order.Id, ct);
Assert.Equal(order.Total, got!.Total);What happened?
- Ephemeral database per test run.
- Apply schema scripts.
- Clean between tests.
Practice next
- Spin LocalDB/Testcontainers.
- Apply schema.
- Insert/read assert.
- Test unique constraint.
- Test proc output param.
Remember
Real SQL engine. Schema scripts. Isolate data.
ShopNest repo integration
CI runs SqlClient against container SQL.
Outcome: Broken procs fail PRs.
