Best practices for writing unit tests with TUnit, including data-driven and advanced testing patterns.

• Use [Test] attribute for test methods; follow Arrange-Act-Assert pattern with naming convention MethodName_Scenario_ExpectedBehavior
• Data-driven testing via [Arguments], [MethodData], and [ClassData] attributes; multiple [Arguments] can apply to the same method
• Fluent async assertions with await Assert.That() syntax; chain with .And or .Or operators and use .Within() for tolerance comparisons
• Lifecycle hooks at multiple scopes: [Before/After(Test)], [Before/After(Class)], and [Before/After(Assembly)] for flexible setup and teardown
• Advanced features include [Repeat(n)], [Retry(n)], [Timeout], [ParallelLimit<T>], and [DependsOn] for test control; parallel execution enabled by default
