I would write functional tests for those controller actions and use the 
Http\Client class to make "real" requests. There should be examples in 
the Flow Functional tests.

I guess building a unit test will be pretty difficult, you might want to 
write unit tests for the actual logic in your models for example.

Additionally you might want to look into Behavior testing with Behat, 
that might also be the right thing for you. We have a package for that
[1] that we also use in Neos for testing, so for examples see the Neos 
package.
