ember js test writing

Hi i am new to ember testing. i have pulled the project from Git and there were some files already present there. when i write ember test in terminal it runs the existing tests or may be the other files because the test directory in my project is empty. Actually i don't know how to write the test case, i have studied the guide and have seen tutorials too but couldn't find anything matching to my case. I know how to create unit or acceptance tests, but i don't know how to write test for my web. Please guide me.
