 - Use `[DataRow]` for inline test data
 - Use `[DynamicData]` for programmatically generated test data
 - Use `[TestProperty]` to add metadata to tests
-- Consider `[CsvDataSource]` for external data sources
 - Use meaningful parameter names in data-driven tests
 
 ## Assertions
 
-* Use `Assert.AreEqual` for value equality
-* Use `Assert.AreSame` for reference equality
-* Use `Assert.IsTrue`/`Assert.IsFalse` for boolean conditions
-* Use `CollectionAssert` for collection comparisons
-* Use `StringAssert` for string-specific assertions
-* Use `Assert.Throws<T>` to test exceptions
-* Ensure assertions are simple in nature and have a message provided for clarity on failure

 ## Mocking and Isolation
 
-* Consider using Moq or NSubstitute alongside MSTest
-* Mock dependencies to isolate units under test
-* Use interfaces to facilitate mocking
-* Consider using a DI container for complex test setups

 ## Test Organization
 
-* Group tests by feature or component
-* Use test categories with `[TestCategory("Category")]`
-* Use test priorities with `[Priority(1)]` for critical tests
-* Use `[Owner("DeveloperName")]` to indicate ownership
