The OSRM project includes a set of cucumber tests that does a lot of testing of binaries, including preparing data and querying the server. It’s ruby based but maybe it can help you. Look in the folder features/. The various support files that queries osrm are in features/support/

See https://github.com/Project-OSRM/osrm-backend/wiki/Cucumber-Test-Suite <https://github.com/Project-OSRM/osrm-backend/wiki/Cucumber-Test-Suite> for more.

Now our problem is we tried several ways to do this, by sending HTTP GET requests to the running server and treat the returned response as JSON. But we tried with Javascript, jQuery and AngularJS, with functions like $resource.get, jQuery.getJSON $http.get or $http.jsonp and we never managed to get the returned response in a way that we could use it for further treatment in our script. Actually, we were able to send the requests to the server but the response is returned in the fom of an URL link which contains the JSON output in its body, not in the form of a variable in our Javascript that we could manipulate.
