Django Testing#

When you create an app the tests.py file is already created

It has the import:

    from django.test import TestCase

So we extend from that to write our test:

    class CourseModelTest(TestCast):
        def test_course_creation(self):
            course = Course.objects.create(
                title="Python Regular Expressions",
                description="Learn to write regular expression in python"
            )
            now = timezone.now()
            self.assertLess(course.created_at, now)

Run the test#

    ./manage.py test

Set Up#

Create your models at beignning of every test

    class CourseModelTest(TestCase):
        def setUp(self):
            model = Course.objects.create(....)

Testing views#

Using the name to get the route to view

    from django.core.urlresolvers import reverse

When testing views you get a self.client which is like a browser

    response = self.client.get(reverse('courses:list'))
    self.assertEqual(response.status_code, 200)

The client has a context on django views

    self.assertIn(self.course, response.context['courses'])
    self.assertIn(self.course2, response.context['courses'])

Testing URL with primary keys#

    response = self.client.get(reverse('courses:step', kwargs={
        'course_pk': self.course.pk,
        'step_pk': self.step.pk
    }))


Use `kwargs`
