- Add .generated directory for test artifacts - Save key derivation data to key_derivation.json - Save account initialization to account_init.json - Save registration data to registration.json - Save claim details to claim_details.json - Save test environment to test-env.sh - Save contacts data to contacts.json - Add proper error handling for file operations - Improve deeplink test flow with JSON-based data - Add color output and better status messages - Add ADB device detection and fallback to print mode Technical Changes: - Add file system operations with proper error handling - Standardize JSON output format across Python/TypeScript - Update test flow to use generated JSON files - Add proper typing for registration response - Improve error reporting and debug output This improves the test workflow by saving all intermediate data as JSON files that can be used by other test scripts. The deeplink testing now uses this data instead of environment variables for better reliability.
