Can someone please help me resolve this? Appreciate your help.

Answer 1

pytest.ini file was somehow got missplaced to another apps folder, which should ideally be placed in root directory of django project folder. for example parallel to settings.py

content of pytest.ini:
[pytest]
DJANGO_SETTINGS_MODULE = nas_apps_proj.settings
python_files = tests.py test_*.py *_tests.py

Answer 2

have you added all the apps in setting.py try this hope this resolves your concern:
Example:
setting.py
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django_user_agents',
'add_your_created_app_here',
]

Answer 3

try this :
INSTALLED_APPS = [ # Rest framework 'django_filters',
 'django_apscheduler', 
 'rest_framework',
 'corsheaders', 
 # Project applications 
'ms_vlan_failover.apps.Usecase1Config',        
'maintenance_check.apps.Usecase2Config', 
'reporting.apps.Usecase1Config', 
# Django defaults 
'django.contrib.admin', 
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions', 
'django.contrib.messages',    
'django.contrib.staticfiles',
'usecase1',
'usecase2',
'usecase3', 
'tests',
 ]

Answer 4

Previous solutions might work in some specific cases. In other ones, take a look if you have installed pytest-django that solved my issue. We were missing this dependency in our requirements.txt and tester has installed it manually.
