1,391 PointsHow i should use assertIn in tests of Django?
I have the following code, but in the code challenge it says "Didn't find 'self.assertIn' "
from django.test import TestCase
from .models import Writer
class WriterModelTestCase(TestCase):
'''Tests for the Writer model'''
def test_writer_creation(self):
writer = Writer.objects.create(name='angelo', bio='no hay bio', email='angelo@noemail.com')
self.assertIn('to angelo@noemail.com', writer.mailto())
from django.db import models
class Article(models.Model):
headline = models.CharField(max_length=255)
publish_date = models.DateTimeField()
content = models.TextField()
writer = models.ForeignKey('Writer')
def __str__(self):
return self.headline
class Writer(models.Model):
name = models.CharField(max_length=255)
email = models.EmailField()
bio = models.TextField()
def __str__(self):
return self.name
def mailto(self):
return 'to {}'.format(self.email)

self.assertIn('to angelo@noemail.com', writer.mailto())
to
self.assertIn(writer.email, writer.mailto())

#from django.test import TestCase #I'd comment this line
#and add this one
from unittest import TestCase
Let me know if this was helpful.
