Running python unit-test cannot find my files in the correct import directory

Question

This is what my code looks like in the code field below. When I run it, the results for my_dir and network_json are equal respectively:

my_dir: C: \ Users \ sepham \ My Documents \ LiClipse Workspace \ sengtool_data_funnel

network_json:

C: \ Users \ sepham \ My Documents \ LiClipse Workspace \ sengtool_data_funnel \ example_EventsOfInterestColumnAggregate.json

But my project directory structure for test_json_networks.py is as follows:

C: \ Users \ sepham \ Documents \ LiClipse Workspace \ sengtool_data_funnel \ tests \ test_networks

json_files_input = [
                'example_EventsOfInterestColumnAggregate.json',
                'example_EventsOfInterestConcatenate.json']
@pytest.mark.parametrize('network_json', json_files_input)
def test_network_jsons(network_json):

    my_dir = os.path.dirname(os.path.abspath(network_json))
    network_json = os.path.join(my_dir, network_json)

    print my_dir
    print network_json

    with open(network_json) as jdata:
        network = Network.load(json.load(jdata))

print operation results:

======================== CAPTURED OUTPUT =========================
C:\Users\sepham\My Documents\LiClipse Workspace\sengtool_data_funnel
C:\Users\sepham\My Documents\LiClipse 
Workspace\sengtool_data_funnel\example_EventsOfInterestColumnAggregate.json

The question is, which variable or environment setting do I need to configure for the Python unit test so that it can see my file in the correct directory at:

C: \ Users \ sepham \ Documents \ LiClipse Workspace \ sengtool_data_funnel \ tests \ test_networks

Answer 3

Maybe you can use the sys module in the python file test_json_networks.py at the beginning of your file

import sys
sys.path.append('C:\Users\sepham\Documents\LiClipse Workspace\sengtool_data_funnel')

This should solve your problem.
