StaticLiveServerTestCase Server Error 500 - django

Question

Main urls.py file:
urlpatterns = [
path(
'admin/',
admin.site.urls
),
path(
'',
include(
'employee.urls'
)
),
path(
'',
include(
'epos.urls'
)
),
path(
'',
include(
'supplier.urls'
)
),
]
epos.urls:
urlpatterns = [
path(
'',
home_view,
name='home'
),
home_view:
#login_required
def home_view(request):
# Get all categories
categories = Category.objects.all()
# Get the first category which will be selected by default
selected_category = categories.first()
# Get the order_items for the selected category (first category)
products = Product.objects.filter(
category=selected_category.id
)
user = request.user
tax = Tax.objects.latest('id')
context = {
'categories': categories,
'user': user,
'title': "EPOS",
'products': products,
'selected_category': selected_category,
'tax': tax
}
return render(request, 'epos/epos.html', context)
Test case:
class LoginTests(StaticLiveServerTestCase):
fixtures = ['fixtures/employee/employee_data.json']
def setUp(self):
self.browser = webdriver.Chrome()
self.browser.get(self.live_server_url)
self.browser.maximize_window()
def tearDown(self):
self.browser.quit()
def test_login_when_clocked_in(self):
import ipdb;ipdb.set_trace()
login_button = self.browser.find_element_by_xpath(
'//button[normalize-space()="Login"]'
)
clock_in_out_button = self.browser.find_element_by_xpath(
'//button[normalize-space()="Clock In/Out"]'
)
pin_input = self.browser.find_element_by_id(
'pin'
)
pin_code = 'some pin'
employee_name = 'some name'
pin_input.send_keys(pin_code)
clock_in_out_button.click()
time.sleep(10)
login_button.click()
settings.py
ROOT_URLCONF = 'allPOS.urls'
LOGIN_URL = '/login/'
When the test logs in I am redirected to the main webpage which is localhost:46497/ but instead of the page I am getting Server Error 500.
This error occurs only when testing. In addition, if I add another path e.g. localhost:46497/analytics it opens the webpage as expected.
Any help would be appreciated.

After 4 hours of debugging, I found out that the issue was related to the database being empty.
The webpage that I wanted to render is expecting some models to be passed, and since the DB was empty those models weren't passed and hence the crash. In normal circumstances ( ./manage.py runserver) if DEBUG=True it will tell you what is wrong, but for some reason StaticLiveServerTestCase doesn't have this option or at least I am not aware of it. If anyone knows how to enable some debugger for the StaticLiveServerTestCase please feel free to add to this thread.
So what I did:
./manage.py dumpdata order.tax > data.json - I dumped the data that I needed into a json file and at the beginning of the TestCase I added that data into the fixture
Hope this helps someone with the same issue!
