No. That's not enough, that's only for your checking.
Your code is still in your local machine. So we don't have access to your code even if you passed all the tests cases.
In order to avoid grade of 0 because of that, you need to git push your local changes to remote so that we can run them and check on Travis.
If you're not so familiar with Git. Knowing these 3 main command will suffice (review lab 0):
git add <file_name>
git commit -m "Commit messages"
git push origin (this pushes changes)
You then check your repo and then will see that it's updated accordingly.
Next, if you open travis you will see your repo being tested by the system.
