Coverage ignoring tests?

Although a passing test exists for the email validation method of my form, when I run coverage, it reports that the method has not been tested. What am I doing wrong?

**Form**
class SignUpForm(forms.ModelForm):
    email = forms.EmailField(max_length=254,
                             error_messages={'invalid': 'Please enter a valid email address.'},
                             label=_('Email address'),
                             widget=forms.EmailInput(attrs={'class': 'form-control mb-4',
                                                            }))

    full_name = forms.CharField(max_length=254,
                                error_messages={'required': 'Please enter your full name.'},
                                label=_('Full name'),
                                widget=forms.TextInput(attrs={'class': 'form-control mb-4',
                                                              }))
    password = forms.CharField(label=_('Password'),
                               widget=forms.PasswordInput(attrs={'class': 'form-control mb-4',
                                                                 'autocomplete': 'new-password',
                                                                 'id': 'psw',
                                                                 }))

    class Meta:
        model = CustomUser
        fields = ('full_name', 'email', 'password')

    def clean_email(self):
        email = self.cleaned_data['email']
        if CustomUser.objects.filter(email=email).exists():
            raise forms.ValidationError(
                    _('A user with that email address already exists, click this <br>'
                      f'<a href="{reverse("accounts:login")}">'
                      'Password Reset</a> link to recover your account.'),
                    code='email_already_exists',
                )

        return email
**Test**

class SignUpFormTest(TestCase):

    def setUp(self):
        self.email = "testclient@example.com"
        self.full_name = "test user"
        self.password = "Ajkklwe1"
        get_user_model().objects.create_user(self.email, self.full_name, self.password)

    def test_user_already_exists(self):
        data = {"email": self.email,
                "full_name": self.full_name,
                "password": self.password,
                }

        form = SignUpForm(data)

        self.assertFalse(form.is_valid())
        self.assertTrue(form.has_error('email', code='email_already_exists'))

Coverage report:

Just a guess here, but what about a test for the other case, where the email does not already exist? Do you have a test for that too?

Hi Ken, yes here it is:

    def test_user_creation(self):
        data = {'full_name': 'Some User',
                'email': 'someuser@gmail.com',
                'password': 'Abhkllklk1',
                }

        form = SignUpForm(data)
        self.assertTrue(form.is_valid())
