Simple Test Returning 404

I have this simple test set up and I'm trying to find out why when I run this test I get this error message. When I visit myapp.app in my browser I see the welcome page for the install of Laravel 5.2.

There were 2 failures:

1) ExampleTest::testExample
A request to [myapp.app] failed. Received status code [404].
