How can I test registering jira issue in Django

I'm trying to test function that connects to Jira and creates Jira issue

My services.py

def get_jira_client():
global jira_client
if jira_client is None:
    jira_client = JIRA(server=JIRA_URL, auth=(jira_user, jira_password))
return jira_client


def register_jira_issue(ticket_id):
    jira = get_jira_client()
    ticket = Ticket.objects.prefetch_related(Prefetch('attachments', to_attr='ticket_attachments'),
                                             Prefetch('tags', to_attr='ticket_tags')).filter(id=ticket_id).first()
    new_issue = add_issue(jira, ticket, ticket.owner)
    set_tags(new_issue, *ticket.ticket_tags)
    add_attachments(ticket.ticket_attachments, new_issue)


def add_issue(jira, ticket, owner):
    issue_dict = {
        'project': {'key': project_key},
        'summary': ticket.title,
        'description': format_text_for_jira(ticket.description),
        'issuetype': {'name': issuetype_name},
        cf_username: str(owner.username),
        cf_hd_grant_id: ticket.grant_id,
        cf_user_email: str(owner.email),
        cf_user_fullname: f"{owner.first_name} {owner.last_name}"
    }

    new_issue = jira.create_issue(issue_dict)
    ticket.key = new_issue
    ticket.save()

    logger.info(f'User {ticket.owner} added issue ')

    return new_issue


def set_tags(jira_issue, tags):
    tags_dict = Tags.objects.filter(id=tags.id).values()[0]
    chosen_tags = [key for key, _ in tags_dict.items() if _ is True]
    if tags_dict['cluster_calculations'] or tags_dict['cluster_installation']:
        chosen_tags.append(tags_dict['cluster'])

    jira_issue.update(fields={"labels": chosen_tags})
    logger.info(f'User set tags {chosen_tags} to issue {jira_issue}')


def add_attachments(files, jira_issue):
    jira = get_jira_client()
    for file in files:
        jira.add_attachment(issue=jira_issue, attachment=file.file)
        logger.info(f'User added attachment {file} to issue {jira_issue}.')

function register jira issue is asynchronously called in views.py and it uses these functions:

• add_issue - registers issue in jira
• set_tags - sets labels for issue
• add_attachments - adds attachment to issue

Does anyone know a way to test ticket registration in jira? I've tried requests_mock but it didn't work for me. I also saw some exapmples of unittest.mock patch but I don't konow how to use it with jira instance
