Status: NEW

(Firefox Build System :: Mach Core, enhancement)

Description

[Nicolas B. Pierron [:nbp]]

Running:

$ mach test devtools/client/webaudioeditor/test/browser_wa_destroy-node-01.js

After instrumenting testing/mochitest/runtests.py as follow:

> try:
>     print "try marionette 1."
>     from marionette import Marionette
>     print "try marionette 2."
>     from marionette_driver.addons import Addons
>     print "try marionette 3."
> except ImportError as err:
>     # Marionette not needed nor supported on android
>     print "try marionette :(.  (%s)" % str(err)
>     Marionette = None

I get the following log:

> try marionette 1.
> try marionette :(.  (No module named pkg_resources)

Listing the paths in the sys.path, only show path to the source directory, the python installation path and the build directory:

This list does not contain any path to setuptools install directory.  To work-around this issue, and make this python script work.  I had to add

> sys.path.append("/nix/store/fp[…]72-python2.7-setuptools-18.0.1/lib/python2.7/site-packages/setuptools-18.0.1-py2.7.egg")

in the runtests.py file.
