SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Writing integration tests for service-layer code requires consistent setup of DI containers, in-memory databases, and assertion patterns. This Skill scaffolds a complete, convention-compliant integration test class so developers avoid recreating test infrastructure or mixing up assertion libraries. ## Core Features & Use Cases - Test Class Scaffolding: Generates a full xUnit test class inheriting from BaseTest<T> with CRUD and pagination test methods. - Convention Enforcement: Ensures Shouldly assertions, real DI resolution, and in-memory EF Core database usage per project standards. - Infrastructure Awareness: References existing BaseTest, CustomWebApplicationFactory, and TestDatabaseInitializer classes so they are never duplicated. - Use Case: When adding a new service like OrderService in the Orders bounded context, generate a ready-to-run OrderServiceTests.cs with seeded-data assertions in seconds. ## Quick Start Ask the AI to create an integration test for your service, for example: create an integration test for IOrderService in the Orders bounded context.

Frequently Asked Questions about create-integration-test

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I write integration tests for a service layer in ASP.NET Core?▼

Create a test class inheriting from BaseTest<IYourService>, which resolves the service from the DI container and exposes it via the _service field. Use xUnit [Fact] methods with Shouldly assertions against an in-memory EF Core database seeded by TestDatabaseInitializer.

Shouldly vs FluentAssertions for integration tests in .NET?▼

This project uses Shouldly for integration tests and FluentAssertions for unit tests, per project convention. Shouldly provides readable assertion messages like result.ShouldNotBeNull() and result.Id.ShouldBe(id).

Can I use Moq mocks in integration tests with an in-memory database?▼

No. Integration tests in this setup use a real DI container with no mocks, unlike unit tests which mock all dependencies with Moq. The CustomWebApplicationFactory replaces SQL Server with an EF Core InMemory database.

How do I test a service that requires an authenticated user?▼

Call SetHttpContextUserId(userId) from the BaseTest class before invoking the service method. This simulates an authenticated user context without needing a real HTTP request pipeline.

Why does my integration test fail when asserting seeded data?▼

Assertions fail when expected entities do not match what TestDatabaseInitializer seeds into the in-memory database. Check the initializer first to confirm which IDs and field values exist before writing assertions.
