为什么我的单元测试用例缺少要在 python 中涵盖的 if 语句？

Question

我已经为一个函数写了一个测试用例。该函数基本上 returns 内容类型为 text/csv 的输出。在运行命令 python3 -m pytest --cov-report term-missing --cov=projfolder/ 之后，我得到了遗漏的行，这些行都在 if 语句中。我对这个问题的理解是测试用例通过了但错过了 if 循环中的语句。看这个例子 func.py

@process_bp.route("/getListCSV")
def get_list_csv():

    companies_flask_list = db.session.query(Companies, LeadsStatus).join(LeadsStatus,
                                                                         Companies.id == LeadsStatus.company_id)

    industry_sele = "All"
    country_sele = "UK"
    size_sele = "All"

    filters = {'open': True, 'assign': True, 'closed': True}

    status_list = ['open', 'allocated', 'converted', 'not converted']

    if 'industry' in request.form:
        industry_sele = request.form['industry']
        country_sele = request.form['country']
        size_sele = request.form['size']

        if not request.form.get('open'):
            filters['open'] = False
            if 'open' in status_list:
                status_list.remove('open')
        if not request.form.get('assign'):
            filters['assign'] = False
            if 'allocated' in status_list:
                status_list.remove('allocated')
        if not request.form.get('closed'):
            filters['closed'] = False
            if 'converted' in status_list:
                status_list.remove('converted')
            if 'not converted' in status_list:
                status_list.remove('not converted')

    if 'industry' in request.args:
        industry_sele = request.args.get('industry')
        country_sele = request.args.get('country')
        size_sele = request.args.get('size')

        if request.args.get('open') == 'False':
            filters['open'] = False
            if 'open' in status_list:
                status_list.remove('open')

        if request.args.get('assign') == 'False':
            filters['assign'] = False

            if 'allocated' in status_list:
                status_list.remove('allocated')

        if request.args.get('closed') == 'False':
            filters['closed'] = False
            if 'converted' in status_list:
                status_list.remove('converted')
            if 'not converted' in status_list:
                status_list.remove('not converted')

所有这些行（如果语句丢失，则在每行中）。看看我对这个功能进行单元测试的方式。 test_func.py

    def test_get_list_csv_manager(self):
        with self.client.session_transaction() as session:
            session['role'] = 'manager'
            session['id'] = 2
        res = self.client.get("/getListCSV", follow_redirects=True)
        self.assertEqual(res.status_code, 200)

我应该如何编写测试用例以便将这些if语句包含在其中？自 5 天以来，我一直在这个问题上陷入困境，我没有任何帮助或运气。

编辑：我是这样尝试的。

    def test_get_list_csv_form_requests(self):
        with self.client.session_transaction() as session:
            session['role'] = 'manager'
            session['id'] = 2

            mock_request_data = {
                'industry_sele': 'Compliance',
                'country_sele': 'UK',
                'size_sele': '5000'
            }
        res = self.client.get("/getListCSV", data=json.dumps(mock_request_data),follow_redirects=True)
        self.assertEqual(res.status_code, 200)

终于找到了我这个问题的答案。对我有用的是这段代码。

    def test_request_form_csv(self):
        with self.client.session_transaction() as session:
            session['role'] = 'manager'
            session['id'] = 2
        r = self.client.get('/getListCSV', data={'industry': 'All', 'country': 'UK', 'size': 'All'})
        self.assertEqual(r.status_code, 200)

Why is my unit test case missing the if statements to cover in python?
