SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps developers write robust and maintainable unit tests in C# using the XUnit testing framework, ensuring code quality and reliability.

Core Features & Use Cases

  • Standard Unit Testing: Learn to structure simple, fact-based tests following the Arrange-Act-Assert pattern.
  • Data-Driven Testing: Implement efficient tests with varying data inputs using [Theory] and data attributes.
  • Test Organization & Isolation: Discover techniques for categorizing tests, managing shared context with fixtures, and isolating units using mocking.
  • Use Case: You need to ensure your C# business logic is thoroughly tested. This Skill guides you in creating effective XUnit tests for both standard scenarios and edge cases with different data inputs.

Quick Start

Use the csharp-xunit skill to generate a basic XUnit test class for a given C# method, demonstrating the Arrange-Act-Assert pattern.

Frequently Asked Questions about csharp-xunit

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

FAQPage Schema
How do I write data-driven unit tests in C# using XUnit?▼

Write data-driven unit tests in C# XUnit by using the [Theory] attribute combined with data attributes like [InlineData] to pass varying inputs. This allows you to test multiple scenarios efficiently without duplicating test methods.

What is the best way to structure a standard XUnit test in C#?▼

The best way to structure a standard XUnit test is using the Arrange-Act-Assert pattern. This separates test setup, execution, and verification, ensuring your C# unit tests remain readable, maintainable, and isolated.

How do I isolate units and manage shared context in XUnit testing?▼

Isolate units and manage shared context in XUnit testing by utilizing mocking libraries and test fixtures. Fixtures provide shared setup across tests, while mocking isolates the target C# code from external dependencies.

Does XUnit support mocking for C# business logic edge cases?▼

XUnit supports mocking for C# business logic edge cases through integration with popular mocking libraries. This ensures thorough testing of both standard scenarios and edge cases by isolating specific code behaviors.

When should I use [Fact] versus [Theory] for C# unit testing?▼

Use [Fact] for C# unit testing when verifying a single static scenario with no inputs, and [Theory] when executing the same test logic against multiple varying data inputs. This distinction ensures proper test coverage and organization.
