FileNotFoundError: [Errno 2] Keine solche Datei oder Verzeichnis: 'test_user1_user_id'

Question

Ich habe einen Fehler FileNotFoundError: [Errno 2] No such file or directory: 'test_user1_user_id'. Ich schrieb in tests.py

from datetime import datetime 

from django.test import TestCase 
from app.models import Companytransaction 
import xlrd 

# Create your tests here. 
class CompanytransactionModelTests(TestCase): 
    def __init__(self, sheet_path): 
     self.book = xlrd.open_workbook(sheet_path) 
     self.sheet = self.book.sheet_by_index(1) 

    def setUp(self): 
     self.book = xlrd.open_workbook('./data/excel1.xlsx') 
     self.sheet = self.book.sheet_by_index(1) 
     num = 0 
     for row_index in range(2,4): 
      row = self.sheet.row_values(row_index) 
       user = Companytransaction(user_id=row[1], name=row[2], age=row[3]) 
       user.save() 

       if num == 0: 
        self.user1 = Companytransaction.objects.create(user_id=row[1], name=row[2], age=row[3]) 
        num += 1 
       elif num == 1: 
        self.user2 = Companytransaction.objects.create(user_id=row[1], name=row[2], age=row[3]) 
        num += 1 
       else: 
        self.user3 = Companytransaction.objects.create(user_id=row[1], name=row[2], age=row[3]) 

    def test_user1_company_id(self): 
     self.assertEqual(self.user1.user_id, '100') 

    def test_user1_corporation_id(self): 
     self.assertEqual(self.user1.name, 'Tom') 

    def test_user1_company_name(self): 
     self.assertEqual(self.user1.age, '29') 

Ich betreiben python manage.py test & ./manage.py test app.tests, aber beide zeigen den gleichen Fehler. Ich machte user_id column in models.py, so dass ich wirklich nicht verstehen kann, warum dieser Fehler passiert. Wie kann ich das beheben? Was soll ich das schreiben?

Hier ist die Rückverfolgung.

Answer 1

Es ist wie die Ausgabe aussieht, ist mit Ihrem __init__ Methode:

def __init__(self, sheet_path): 
    self.book = xlrd.open_workbook(sheet_path) 
    self.sheet = self.book.sheet_by_index(1) 

Sie diesen Fehler, weil Sie nicht sheet_path bereitstellen, wenn CompanytransactionModelTests initialisiert wird. Wir können aus dem unittest.TextCase source sehen, dass modelName das erste & einzige Argument bei der Initialisierung eines TestCase ist. Ich wette einen Cent, dass Sie eine Methode namens test_user1_user_id auf einer Klasse mit ähnlichen __init__ Code haben.

Das Einrichten dieser Testdaten in setUp ist der richtige Weg, um das zu tun, was Sie tun. Es sieht so aus, als ob die Dinge richtig funktionieren sollten, wenn Sie diesen Code __init__ loswerden.
