Unit Testing with PHP OAuthProvider

I have written an OAuthProvider service on my end in ZendFramework2 that will take oauth 2-legged and 3-legged requests to my resources.

I am mainly trying to test out that my callbacks tokenHandler, consumerHandler, timestampTokenHandler are returning proper values on \OAuthProvider->checkOAuthRequest

Has anyone ever done this before? Or am I going about this wrong?

My current response from checkOAuthRequest() in my test suit is like so:

oauth_problem=parameter_absent&oauth_parameters_absent=oauth_consumer_key%26oauth_signature%26oauth_signature_method%26oauth_nonce%26oauth_timestamp%26oauth_tokenroot@6fb8e48ac790
