- Use `[ClassFixture<T>]` for shared expensive setup across tests in a class. Use `[CollectionFixture<T>]` for sharing across multiple test classes. Use `IAsyncLifetime` for async setup/teardown instead of constructor/Dispose. Mock dependencies with Moq or NSubstitute: `Mock<IService>().Setup(x => x.Method()).Returns(value)`.
