Chef - Chef-Client Run

In order to test Chef-Client run, we need to have Chef-Client configured to use the hosted Chef or own hosted server.
vipin@server:~$ sudo chef-client -l debug

In order to check the last Chef-Client run especially failure issues when we are developing a new cookbook, we need to know what exactly went wrong. Even though Chef prints everything in stdout, one might want to see the debug log again.
If we want to test, we need to have a broken cookbook which is failing on compilation.
user@server:~$ sudo chef-client
