SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the complexity of maintaining high-quality, reliable F# codebases by providing standardized patterns for unit, integration, and property-based testing.

Core Features & Use Cases

  • Comprehensive Assertion Patterns: Utilize FsUnit and Unquote for readable, expressive test outcomes.
  • Property-Based Testing: Leverage FsCheck to automatically verify invariants and edge cases in your domain logic.
  • Integration Testing: Implement robust infrastructure tests using WebApplicationFactory and Testcontainers for ASP.NET Core applications.

Quick Start

Use the fsharp-testing skill to generate a new xUnit test file for the OrderService module using Unquote assertions.

FAQPage Schema
How do I write unit tests for F# using xUnit?

F# unit testing with xUnit is standardized using FsUnit and Unquote to provide readable, expressive assertions. This approach ensures code reliability by automating test organization and facilitating clear test outcomes for .NET applications.

What is property-based testing in F# and how does FsCheck work?

Property-based testing in F# uses FsCheck to automatically verify invariants and edge cases in domain logic. It generates varied test inputs programmatically, ensuring your F# code handles a wider range of scenarios than traditional example-based tests.

How do I set up integration testing for ASP.NET Core in F#?

ASP.NET Core integration testing in F# is implemented using WebApplicationFactory and Testcontainers. This setup facilitates robust infrastructure testing within the .NET ecosystem, ensuring your web applications function correctly under realistic conditions.

What's the best way to create expressive assertions for F# tests?

The best way to create expressive assertions in F# is using FsUnit and Unquote. These libraries allow you to write tests that read naturally, making outcomes easier to verify and maintaining high-quality, reliable F# codebases.

Does this approach support mocking strategies within the .NET ecosystem?

Yes, this F# testing methodology supports mocking strategies within the .NET ecosystem. It standardizes unit tests and integration tests, allowing you to isolate dependencies effectively while ensuring code reliability through automated test organization.
