Make Test Cases Readonly in Azure DevOps Services

This post details how to make 'Test Case' work items read-only in Azure DevOps Services using inherited process templates. It outlines the creation of custom rules to achieve this: 1. Making all fields read-only when the work item state is 'Ready'. 2. Restricting transitions from 'Ready' to 'Design' and 'Ready' to 'Closed'. This provides a mechanism to freeze test cases after they are constructed and moved to the 'Ready' state.
