- Introduced for independent mathematical operations and RSA fixtures. - Implemented for testing DMA channels with AES ECB and memory interactions. - Created to validate RSA-2048 operations and Montgomery reduction. - Developed for testing AES and SHA vector compliance. - Added to validate image packing, integer root calculations, and inventory checks. - Ensured robust error handling and validation in tests to catch data corruption and recursive hierarchy issues.
