The standard naming convention for .NET unit tests uses a three-part format: <Method>_<Scenario>_<Expected>. This structure improves test readability, maintainability, and makes the test intent clear across the codebase.

To name test classes in .NET, append the suffix "Tests" to the class name, such as CalculatorTests. For parameterized tests, follow a consistent format like Method_Scenario_Input_Expected for each data case to ensure readability and traceability.

Using a consistent test naming scheme resolves the problem of inconsistent test names that make .NET codebases hard to read and maintain. Standardizing method, class, and parameterized test names improves clarity and documents test intent effectively.

The three-part test naming format covers common .NET unit testing scenarios including standard method naming, test class naming, and parameterized test naming. It provides templates for consistent documentation across these testing situations.

The best way to document test intent in .NET unit tests is applying the three-part naming scheme: <Method>_<Scenario>_<Expected>. This format standardizes naming to explicitly state what scenario is tested and what the expected outcome is.

You need to standardize test naming conventions in a .NET project when inconsistent naming makes tests hard to read, maintain, and reason about, requiring a structured format to enforce clarity and consistency across the codebase.
