My problem turned out to be that my application and my virtual environment have the same name. So if you're using virtualenvwrapper and your venv is called apps or accounts try making a new one with a different name.

When i run python manage.py tests i get an error saying that some test module is not found.
I am using PyCharm, Django 2.1.4 and W10 on Ubuntu.
The error:

I just want to run my tests like in any other django project...
I have never encountered this problem before so any help is appreciated! :)
Well, well...it turns out that changing the folder was the solutio, though i have projects working that share the same folder name so i don't really know what happend with this one.
Before:
Django
│ └── projectname
│ └── projectname
After:
Django

The DJANGO_SETTINGS_MODULE parameter should be set from the root of your project, that should be:
os.environ.setdefault("DJANGO_SETTINGS_MODULE",
"server.settings")
I've cloned the flaskr application from Github and am trying to follow the Testing Flask Applications tutorial. Following Bonus: Testing the Application, I've added a subdirectory test to the top-level flaskr directory, so that my directory tree looks like this:
.

├── setup.py
├── test

└── tests
└── test_flaskr.py
Note that there are also 'built-in' tests in the directory tests; however, I'm writing tests in test_flaskr.py in the directory tests. So far I'm trying just one test:
import os
import flaskr
import unittest
import tempfile
class FlaskrTestCase(unittest.TestCase):
def setUp(self):
self.db_fd, flaskr.app.config['DATABASE'] = tempfile.mkstemp()
flaskr.app.config['TESTING'] = True
self.app = flaskr.app.test_client()
with flaskr.app.app_context():
flaskr.init_db()
def tearDown(self):
os.close(self.db_fd)
os.unlink(flaskr.app.config['DATABASE'])
def test_empty_db(self):
rv = self.app.get('/')
assert b'No entries here so far' in rv.data
if __name__ == '__main__':
unittest.main()
However, if I try to run this I get the following error:
Traceback (most recent call last):
File "/home/kurt/dev/scratch/flask/examples/flaskr/test/test_flaskr.py", line 13, in setUp
flaskr.init_db()
AttributeError: 'module' object has no attribute 'init_db'
I don't understand this error. My flaskr.py is the same as the one on https://github.com/pallets/flask/blob/master/examples/flaskr/flaskr/flaskr.py and has an init_db function defined. How can I make the unit test run?
When you import the flaskr package in your script, you can access the variables, functions etc. declared and defined in flaskr/__init__.py
init_db is not defined in flask/__init__.py, the code provided, expects init_db to be defined in flask/__init__.py.
There are two ways to fix the issue you have:
Replace flaskr.init_db() with flaskr.flaskr.init_db()
Modify the import statement in test_flaskr.py as follows:
Change import flaskr to from flaskr import flaskr
I am following along with this tutorial:
http://www.marinamele.com/taskbuster-django-tutorial/create-home-page-with-tdd-staticfiles-templates-settings
When I run:
(tb_test)metersk:functional_tests metersky$ python test_all_users.py
.
----------------------------------------------------------------------
Ran 1 test in 2.313s
OK
The test works as it should. The test being :
from selenium import webdriver
import unittest
class NewVisitorTest(unittest.TestCase):
def setUp(self):
self.browser = webdriver.Firefox()
self.browser.implicitly_wait(3)
def tearDown(self):
self.browser.quit()
def test_it_worked(self):
self.browser.get('http://localhost:8000')
self.assertIn('Welcome to Django', self.browser.title)
if __name__ == '__main__':
unittest.main(warnings='ignore')
However, when I follow the step to add a blank __init__.py file to the directory, and I run the test like so: python manage.py test functional_tests
I get a the following failure:
Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: set the SECRET_KEY environment variable
I don't quite understand how calling the test script differently from the command line would prevent the program from finding the secret key environment variable. It clearly works when I call the script on its own.

Do you change your Mysql backend?
Support for using Google Cloud SQL with Django is provided by a custom Django database backend which wraps Django's MySQL backend.
edit your settings.py:
DATABASES = {
'default': {
'ENGINE': 'google.appengine.ext.django.backends.rdbms',
'INSTANCE': 'my_project:instance1',
'NAME': 'my_database',
}
}
