Only function definitions covered by unit testing python/flask backend -

i start saying beginner @ both flask , unit testing in python, bare in mind.

i writing unit testing backend building android app. trying write tests functions communicate android client when write them, definitions of each function i'm testing registered covered.

my registration function example, looks this:

@app.route("/register", methods=['post']) def register():     register_args = request.get_json(force=true)     if not ('username' in register_args , 'email' in register_args , 'password' in register_args):         abort(406)      new_username = register_args['username']     new_email = register_args['email']     new_password = register_args['password']      if user.query.filter_by(username=new_username).all() or user.query.filter_by(email=new_email).all():         abort(406)     else:         u = user(username=new_username, email=new_email, password=new_password)         db.session.add(u)         db.session.commit()         return jsonify(u.as_dict()) 

and test looks this:

    def test_registration(self):         registration_url = "http://127.0.0.1:5000/register"          #password missing         data = json.dumps({'username': 'danilzorz', 'email': 'danilzorz@awesome.com'})         response = requests.post(registration_url, data)         print("missing password http-code: " + str(response.status_code))          #correct registration         data = json.dumps({'username': 'danilzorz', 'email': 'danilzorz@awesome.com', 'password': 'hejhej'})         response = requests.post(registration_url, data)         print("correct registration http-code: " + str(response.status_code))         self.asserttrue(response.status_code == 200)          #username taken         data = json.dumps({'username': 'danilzorz', 'email': 'dude@dude.com', 'password': 'hejhej'})         response = requests.post(registration_url, data)         print("incorrect registration http-code: " + str(response.status_code) + "\n")         self.asserttrue(response.status_code == 406) 

but rows containing app route , function definition tested according both pycharms built in coverage tester , nosetests.

so question is, should coverage rest of function?

any appreciated.

edit: using python 3.4

you should able create request context , call method directly

def test_register():     app = flask(__name__)     ctx = app.test_request_context(path="/register?get_arg1=55",method="post",data={"username":"frank","email":"f@ra.nk","password":"password"})     ctx.push()     assert register() == expected_register_output 

another alternative pull business logic out of view function

 def do_register(username,email,password):      # // actual registration here , return new user object  @app.route("/register",...)  def register():      username,password,email = request.form["username"],...      if do_register(username,email,password):         return registration_success      return registration_errors 

then call do_register on test ...

an yet alternative provide comments tell pycov ignore method

 @app.route("/register",...)  def register(): # pragma: no cover      ....
