Is it possible to somehow make a testing system like in Google Forms?

Question

Software testing

The bottom line is to implement a constructor for testing.
Those. the admin sets this test, similar to the one in the constructor (the ability to add a photo, video, a different number of questions and answers, etc.).
And users go through it and the result is displayed to the admin.
In my opinion, Google Forms has the perfect performance.
There most likely everything is on js and ajax.
The question is, are there any similar ready-made solutions or in which direction to dig?
