Run Build test from my local machine. How?

Hi there
I have the GitLab runner installed on my machine and I wand to test my Build script with a command/commands typing it locally. How to launch the build job and see the success/failure in command line?

I tried

MyDisk:\GitLab-Runner\GitLab-runner exec shell
or
MyDisk:\GitLab-Runner\GitLab-runner exec shell build

both result in

“fatal: not a git repository (or any of the parent directories): .git”
or
“FATAL: no job named “build””

Thoughts?

Thanks.
