Developer creates 15-line test for fearless schema refactoring

By PulseAugur Editorial · [2 sources] ·

This test aims to eliminate the fear associated with schema refactoring by providing explicit error messages when discrepancies arise. The test, which compares values between the database and the TypeScript code, allows for safer and faster modifications, such as renaming database statuses, by catching potential issues before they reach production.
