Во время вызова pytest из оболочки я получаю следующий вывод, поскольку мой тест хранится в apps.business.metrics.tools.tests.py, а во время импорта модуля
apps/business/metrics/widgets/employees/utilization.py
делает живой вызов SQL во время вызова модуля. Это делается
get_metric_columns('EmployeeUtilization', shapers=SHAPERS)
и жалобы на pytest:

Есть ли способ справиться с такой ситуацией с помощью pytest?
Я понимаю, что могу преобразовать get_metric_columns('EmployeeUtilization', shapers=SHAPERS) в частичную функцию и изменить реализацию, но есть ли другой способ?
