dotnet-add-testing
Add test infrastructure scaffolding to an existing .NET project. Creates test projects with xUnit, configures code coverage with coverlet, and sets up the conventional directory structure.
Scope boundary: This skill provides test project scaffolding only. For in-depth testing patterns -- xUnit v3 features, integration testing with WebApplicationFactory, UI testing, snapshot testing, test quality metrics, and testing strategy guidance -- see [skill:dotnet-testing-strategy] and the related testing skills.
Prerequisites: Run [skill:dotnet-version-detection] first to determine SDK version and TFM. Run [skill:dotnet-project-analysis] to understand existing solution structure.
Cross-references: [skill:dotnet-project-structure] for overall solution layout conventions, [skill:dotnet-scaffold-project] which includes test scaffolding in new projects, [skill:dotnet-add-analyzers] for test-specific analyzer suppressions.
Test Project Structure
Follow the convention of mirroring src/ project names under tests/:
MyApp/
├── src/

Production-grade logging and observability patterns for ASP.NET Core Razor Pages. Covers structured logging with Serilog, correlation IDs, health checks, request logging, OpenTelemetry integration, and diagnostic best practices. Use when setting up structured logging in ASP.NET Core applications, implementing distributed tracing with OpenTelemetry, or configuring health checks and observability.
357testcontainers
Patterns for using Testcontainers in .NET integration tests to spin up real dependencies like databases and message queues. Use when writing integration tests that require real databases, testing with message brokers like RabbitMQ or Kafka, or isolating test dependencies with Docker containers.
357microsoft-extensions-dependency-injection
Dependency injection patterns and best practices using Microsoft.Extensions.DependencyInjection for .NET applications. Use when configuring DI containers in .NET, choosing between service lifetimes (Singleton, Scoped, Transient), or implementing decorator patterns and service interception.
354project-structure
Guidelines for organizing .NET projects, including solution structure, project references, folder conventions, .slnx format, centralized build properties, and central package management. Use when setting up a new .NET solution with modern best practices, configuring centralized build properties across multiple projects, implementing central package version management, or setting up SourceLink for debugging.
