It seems like what you're asking doesn't quite align with how Angular functions. Angular itself doesn't prevent requests from being sent for any specific reason. If your form is not sending a request, it's likely due to how you've programmed it. Disabling validation in this scenario would involve removing or commenting out the code that enforces it (unless you're using custom validators, which can complicate things).
However, I wouldn't recommend completely disabling validation. To test your server-side validation, consider one of the following approaches:
- Write automated tests in the same programming language as your back-end to verify that your validation logic is functioning correctly;
- Manually test by directly calling your back-end API. Tools like Fiddler for Windows or Postman for Google Chrome on any operating system could be helpful.
