It's finally time to test out the automation you've put in place. Ensure that you have a clone of your Git repository available on your local machine. From the folder in which the code resides, add a new file:

$ touch newfile.txt 

Now add this file to Git, commit this change, and push the changes to the code repository:

$ git add . 
$ git commit -am "New file added" 
[main b4c1143] New file added 
1 file changed, 0 insertions(+), 0 deletions(-) 
create mode 100644 newfile.txt 
$ git push origin main
