Description

The tests were failing on CD pipeline with the following error:

git_clone_test.go:116: Git empty commit failed: : failed command '/bin/bash -c git commit --allow-empty -m " empty commit"': exit status 128, Author identity unknown
        
        *** Please tell me who you are.
        
        Run
        
          git config --global user.email "you@example.com"
          git config --global user.name "Your Name"
        
        to set your account's default identity.

Fixed by setting the user config before running the tests.
