Ian
The following is still useful after more than a year. Thanks !!
I made some modifications - mostly my specific paths before calling
run_pytest, and my run_test.py is in scripts folder rather than bin.
I'm getting an error :
NameError: name 'db' is not defined
I'm running it as :
python web2py.py -S myapp -M -R applications/myapp/scripts/run_tests.py
Any ideas ?
