What it does

Provides XUnit best practices for C# unit testing, covering test structure, naming conventions, assertions, and data-driven tests with Theory and InlineData.

Overview

This skill provides XUnit best practices for writing effective C# unit tests, covering both standard and data-driven testing approaches. It guides test project setup, naming conventions, the Arrange-Act-Assert pattern, assertions, data-driven tests with Theory and InlineData, mocking with Moq, and shared test context using fixtures.

Key Features

XUnit Test Structure - Enforces [Fact] for simple tests and [Theory] for data-driven tests with proper naming conventions (MethodName_Scenario_ExpectedBehavior) and constructor-based setup/teardown
Data-Driven Testing - Guides usage of [InlineData], [MemberData], [ClassData], and custom DataAttribute implementations for comprehensive parameterized test coverage
Fluent Assertions - Recommends FluentAssertions library for readable, chainable assertions with natural language syntax alongside standard Assert methods
Mocking with Moq - Covers Mock<T> setup, callback verification, argument matching, and behavior configuration for isolating dependencies in unit tests
Shared Context Management - Implements IClassFixture<T> for class-level shared context and ICollectionFixture<T> for cross-class shared resources to optimize test execution

Who is this for?

C# developers who want to write robust, maintainable unit tests using the XUnit framework. Ideal for .NET teams adopting test-driven development or migrating from MSTest/NUnit to XUnit who need guidance on XUnit-specific patterns, data-driven testing, and modern assertion libraries.
