I have written a feature test in Behave Python Selenium. When i run the test it throws the error ImportError No module named pages. I think it cannot find my classes in the pages directory. homepage.py, searchpage.py
Is my imports incorrect? How can i resolve this issue?
The full error is:

My code is as follows:

My directory structure is as follows:

E:\selenium_test\pages\__init__.py
Thanks, Riaz
Preferred
Move pages under feature/steps. Add init file. Then import just works
Harder
Update sys.path to include the location of 'pages'. You can do this from environment.py or steps.py itself
Fiddly
import imp
myPkg = imp.load_source('module.name', '/path/to/pages/file.py')
Just to know:
export PYTHONPATH=$PYTHONPATH:/abs/path/to/pages. Not recommended though.
