updated - test run failure observations: observations are, testtoppage() - line 72 passed response 200. fails @ line 84 because contents not have project _id.

for testsendmessage() - fails 404 error @ line 133, url = getappbaseurl() + "send_message"; there no such resource.

similarly,testpushhandlerisprotected()- fails 404 error @ line 110 there no such resource.

note: project has hello world application in appengine these test methods looking resource not present in appengine. missing?

have @ line 31 in test. uses different environment variable called 'test_project_id' (see line 24). should simple setting correct environment variable. add debug output url in unit test know hostname used.

edit1: mean, have hello world application in appengine? 'send_message' resource , init_servlet, returns project id asserted line 84 defined in web.xml of sample. have deploy application before run tests against (or find instance of app running). if can't deploy app because tests failing, can skip surefire tests adding -dskiptests parameter maven command. explained in readme of project.
