Was kann dazu führen, dass dieses Unicode-Objekt in nosetests lib nicht aufrufbar ist?

Question

Ich habe einen Testfall, der eine Strömung in einem API-Tests (verwendet requests.Session() und mehrere Anrufe zu unserem Backend macht.)

Dieser Testfall geht auf meinem Mac und anderen Völkern macs. Aber wenn es in Jenkins ausgeführt wird, bekomme ich einen Fehler. Es gibt andere ähnliche Testfälle wie diese, die ohne Probleme in Jenkins bestehen. Leider kann ich den Testcode nicht selbst teilen.

Jenkins läuft auf Ubuntu 14.04

Aber hier sind erste Zeilen des Testcodes, wenn es hilft.

# filename: test_payment_visa.py 

import unittest 
from tests.utils import WWHTTPClient 
import math 
from nose.plugins.attrib import attr 


class TestPaymentWorkflow(unittest.TestCase): 
    def setUp(self): 
     self.ww_api = WWHTTPClient() 

    def test_payment_visa(self): 
     """Test for Payment Workflow via VISA""" 

Hat jemand eine Idee, was damit verbunden werden kann?

Answer 1

Also gab es ein Problem mit meinem Code.

benutzte ich eine Erklärung self.id = r.json()["orders"][0]["id"]

# filename: test_payment_visa.py 

import unittest 
from tests.utils import WWHTTPClient 
import math 
from nose.plugins.attrib import attr 


class TestPaymentWorkflow(unittest.TestCase): 
    def setUp(self): 
     self.ww_api = WWHTTPClient() 

    def test_payment_visa(self): 
     """Test for Payment Workflow via VISA"""  
     ... 
     ... 
     self.id = r.json()["orders"][0]["id"] 
     ... 
     ... 

Problem ist, dass unittest.TestCase cla ein Verfahren id genannt hat.

def id(self): 
    """Get a short(er) description of the test 
    """ 
    return self.test.id() 

Also gehe ich davon aus, dass ich während der Testlauf self.id auf einen Unicode-String gesetzt und dann nosetests versucht, seine id Methode aufrufen und TypeError: 'unicode' object is not callable Ausnahme erhält.
