Ensure all testing-related documentation is clear, accurate, and user-focused. Use precise terminology when describing test components, fully explain configuration attributes with their effects, and provide complete examples that demonstrate proper usage. When documenting test blocks and attributes: - Use exact parameter names and describe their full behavior - Explain default values and all possible options - Reference related sections for context For example: ```hcl test "configuration_example" { # Document that this enables parallel execution of all run blocks # within this test unless specifically overridden parallel = true } run "validate_resource_properties" { # Document that this block contains validation logic # with clear explanation of the condition and error message condition = local.resource_name != "" error_message = "Resource name cannot be empty" } ``` Well-documented tests serve as both validation tools and self-explanatory examples, making your codebase more maintainable and helping new team members understand testing requirements quickly.
