NUnit 3 Testing

What it does

Generates practical NUnit 3 unit tests in C#, demonstrating the Assert.That constraint model, parameterized tests (TestCase/TestCaseSource), test lifecycle hooks (SetUp/TearDown/OneTimeSetUp), and examples of mocking with Moq. Includes runnable examples and CI/test run guidance.

When to use it

Use this skill when you need to scaffold or improve C# unit tests, convert informal test ideas into proper NUnit tests, add parameterized cases, or learn idiomatic NUnit patterns for assertions and lifecycle management. Triggered by mentions of NUnit, [Test], Assert.That, C# testing, or unit-test related requests.

What's included

• Scripts: none detected in repo for this skill (has_scripts=false)
• References: limited — the skill body points to a reference/playbook for deeper patterns (has_references=false)
• Instructions: concrete code examples for basic tests, constraint-based assertions, parameterized tests, Moq-based mocking patterns, lifecycle attributes, categories/attributes, anti-patterns, and commands to run (dotnet test).

Compatible agents

Likely compatible with developer-focused agents that can edit or generate code (Copilot/Codex/GitHub Copilot-style assistants and other code-capable LLM agents).
