[Feature]: Add fuzzing testing framework and tests

[sxd]

Is there an existing issue already for this feature request/idea?

• [x] I have searched for an existing issue, and could not find anything. I believe this is a new feature request to be evaluated.

What problem is this feature going to solve? Why should it be added?

One of the failures that the project has right now is that we lack of Fuzzing testing that is described here https://go.dev/doc/security/fuzz/ and we should have them because we fail the Fuzzing section of the OpenSSF Scorecard Report
