Many similar sandboxed tests on sockets generated by Fuzzing and not minimized #1129

[Markoutte]

Description

There's no coverage trace when error occurs before the method is invoked. Therefore, fuzzer generates too many values which are not minimized later. To fix this issue fuzzer now compares stack traces of the error to minimize test number.

Similar behavior can be implemented in other places.

Fixes #1129

Type of Change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Automated Testing
