Does anyone have any experience with using different settings files for the Django test runner in PyCharm?

My project is composed as follows:

```
+penguinproject
+apps
+settings
--__init__.py
--common.py # this one is imported by the others below
--development.py
--production.py
--staging.py
+static
...

```

Running the tests with a manage.py command (and adding --settings=settings.development) works fine, but I'd like to use the built in test runner (as it's better integrated with the IDE).

I *think* the problem is that my settings aren't being loaded correctly, as I get this error:

```

raise ImproperlyConfigured("App with label %s could not be found" % app_label)

```

I don't get this error using manage.py from the command line (also when invoked from within the IDE), which makes me think the development.py settings aren't loaded correctly. Debugging shows that within get\_app() (in the loading.py module) settings.INSTALLED\_APPS is an empty list.

Has anyone succeeded in setting up the test runner with this setup of settings files?

Many thanks in advance!
