Current Behavior: The 'Kinds to Test' section currently proposes samples based on the kind to test. However, since each kind can have multiple mapping blocks, this approach doesn't provide appropriate samples to validate individual mappings effectively. Proposed Change: Modify the testing section to propose samples based on mapping blocks instead of kinds. This change will allow users to select appropriate mapping samples to test specific mappings more accurately. Benefits: Improved mapping validation: Users can test each mapping block individually, ensuring more thorough and accurate testing. Better test coverage: By focusing on mapping blocks, we can ensure that all mappings are tested, not just a general sample for each kind. Increased efficiency: Testers can pinpoint and validate specific mappings more easily, potentially reducing the overall testing time. Implementation Details: Update the sampling algorithm to consider individual mapping blocks rather than just kinds. Modify the user interface to display mapping block-specific samples. Ensure that the sample selection process covers all mapping blocks within each kind.
