A solid reference for NUnit testing patterns that covers the practical stuff you actually need. Walks you through proper test project setup with the right NuGet packages, explains the AAA pattern and good naming conventions, and shows you how to use TestCase and TestCaseSource for data-driven tests. The constraint model assertions (Assert.That with Is.EqualTo) are well-explained since they're more readable than the classic style. Good coverage of attributes like SetUp, TearDown, and Category for organizing tests. If you're moving from MSTest or just want to write cleaner NUnit tests, this hits the common scenarios without getting lost in edge cases.
