Probablemente quieras probar el proveedor externo una vez, pero no necesariamente llamarlo para cada test que se realice.

En este caso, puedes sobrescribir la dependencia que llama a ese proveedor y usar una dependencia personalizada que devuelva un usuario de prueba, solo para tus tests.

Asegúrate de tener [tests](../tutorial/testing.md){.internal-link target=_blank} para tu app y de ejecutarlos en integración continua (CI).

Así podrás hacer la actualización y asegurarte de que todo sigue funcionando como esperas.

3. **Testing**:
   - Include unit tests for new functionality or bug fixes.
   - Ensure existing tests pass (`make test`).
   - Document testing steps in the PR summary if manual testing was performed.

4. **Before Submitting**:
   - Run `make verify` to check formatting, linting, and tests.
   - Reference related issues (e.g., “Closes #1234”).
