Testing Now That I'm Not Using Rails?

This morning I continued to work through the Rebuilding Rails book and I completed Chapter 4 where we created the functionality to use views and erb templates.

I then went back to working on the Longest Streak app that I started yesterday. I fixed the 4 tests that I currently have that I broke yesterday while I was experimenting a bit. Now that I’m getting the data I need from the GitHub API I need to start storing stuff in my database, but now I’m not really sure how to go about testing this part of the application. I know I could just start dumping data in the database without tests, but thats what I’m trying to avoid.
