Testcases for SIgnals Django

Hi I have been trying to write the test case for the following post save signal, without any success. Can anyone help.

@receiver(post_save, sender=Item, dispatch_uid="item_created")
def notify_member_item_create(sender, instance, **kwargs):
        email_subject = "email_subject"
        email_body = "email_body"
        email_list = [instance.inventory.owner.email]
        send_mail(email_subject, email_body, settings.EMAIL_HOST_USER, email_list)
