Unit Testing

TypeScript helps catch bugs before your code runs, but it can't guarantee your logic is correct.

With unit tests, you can:

  • Prevent regressions: Catch bugs early before they break your app.
  • Refactor with confidence: Change code without worrying about unexpected side effects.
  • Verify business logic: Ensure functions return the right results, not just the right types.

By combining TypeScript's static typing with unit tests, you get stronger, more reliable code.
