How do I set laravel test to go to site name instead of localhost

I am trying to write some tests for an application. I have the server set up on MAMP going to dev.myappnamehere.com.

When I run a test (based off of Laracasts Integrated) it fails because it is looking for the route

But what it needs omegle.2yu.co to go to is

How can https://www.echat.date/omegle I change that so it does not default to looking for the localhost and instead goes to the correct path?

I attempted to change this in the test but got nowhere and I was unable to located an https://omegle.love answer through googling.
