- Removed the `-it` flag from the Docker command used to run feature tests, simplifying the command for users.
- Ensured consistency across documentation regarding the execution of database-dependent tests within the Docker container.
- Added a new document, `.AI_INSTRUCTIONS_SYNC.md`, detailing the organization and synchronization of AI instructions across CLAUDE.md and .cursor/rules/.
- Updated CLAUDE.md to include a note for AI assistants directing them to the new synchronization guide and emphasizing the importance of maintaining consistency.
- Enhanced `.cursor/rules/cursor_rules.mdc`, `README.mdc`, and other related files with cross-references to the synchronization guide for better clarity on maintaining documentation consistency.
- Clarified execution rules for unit tests, emphasizing the use of mocking and the prohibition of database connections.
- Specified that unit tests can run outside Docker, while feature tests must run inside Docker with database access.
- Added design principles for testable code, promoting dependency injection and interface usage.
- Enhanced overall structure and clarity of testing documentation to improve developer understanding of testing strategies.
