Reverse Throwing an Error for Step Detail View Test

Question

I'm trying to work through writing course detail and step detail view tests like Kenneth recommended at the end of the video. I'm running into the following error for my step detail view test:

TypeError: step_detail() got an unexpected keyword argument 'course_pk'

If anyone has any suggestions as to why I'm getting this error it would be greatly appreciated! Here is my code:

tests.py

class CourseViewsTest(TestCase):
    def setUp(self):
        self.course = Course.objects.create(
            title="Python testing",
            description="learn to write tests"
        )
        self.step = Step.objects.create(
            title="I'm a step",
            description="I'm a step description",
            course=self.course
        )

    def test_step_detail_view(self):
        resp = self.client.get(reverse('courses:step', kwargs={'course_pk':self.course.pk, 'step_pk':self.step.pk}))
        self.assertEqual(resp.status_code, 200)
        self.assertEqual(self.step, resp.context['step'])

urls.py

urlpatterns = [
    url(r'^$', views.course_list, name='list'),
    url(r'(?P<course_pk>\d+)/(?P<step_pk>\d+)$', views.step_detail, name='step'),
    url(r'(?P<pk>\d+)/$', views.course_detail, name='detail'),
]

views.py

def step_detail(request, pk):
    step = get_object_or_404(Step, course_id=course_pk, pk=pk)
    return render(request, 'courses/step_detail.html', {'step': step})

In your views.py:

def step_detail(request, course_pk, pk): # course_pk was needed here
