i using pytest and coverage for testing django project But I don't know how to test the else block that has return redirect("account_login") and fix the red part that says coverage.

In your opinion, how can I write a test for that else piece and fix the red part that says coverage?

views.py

@verified_email_required
def profile_view(request, username):
    # We check if the user is logged in?
    if request.user.is_authenticated:
        try:
            profiles = Profile.objects.all()[:4]
            # get user profile by username
            profile = Profile.objects.get(user__username__iexact=username)
            user = User.objects.get(username=username)
            user_following = following(user)
            user_followers = followers(user)
            logged_in_user_following = following(request.user)
            logged_in_user_followers = followers(request.user)
            # if user not found raise 404 error
        except ObjectDoesNotExist:
            raise Http404
        # context data
        context = {
            "user": user,
            "profile": profile,
            "profiles": profiles,
            "following": user_following,
            "followers": user_followers,
        }
        return render(request, "user_profile/profile.html", context)

    # if a user is not login in redirecting to login page
    else:
        return redirect("account_login")

CodePudding user response：

I suspect you won't be able to as your decorator @verified_email_required will prevent any unlogged in people from reaching that line of code.

My assumption here is that you are using allauth as it provides a decorator of that precise name. See https://django-allauth.readthedocs.io/en/stable/decorators.html which states: If the user isn’t logged in, it acts identically to the login_required decorator.
