Group doesn't work with multiple source folders

[mdharamadas]

I have src_folders defined as below with multiple folder paths. Each of these folders in turn have folders like functional, api, etc.

{
  "src_folders": ["tests/home", "tests/login", "tests/register"],
  ...
}

I can successfully run all tests (without specifying --group) but cannot run tests with groups like below. NigthWatch doesn't consider src_folders if groups are specified.

./nightwatch --group functional -e chrome

This is a weird one. If you use multiple test paths and then include a group, what you end up with is a test path that uses the group rather than src_folders. So given OP's config and a structure like:

root/
+- nightwatch.json
+- tests/
|  +- home/
|  +- login/
|  +- register/
+- functional/

the tests in root/functional get run.

The code calls out to the fact that it only works with one src_folders, but I'm not sure why first condition returns the group as the src path when there are more than one specified.

I have a feeling this is something our team will run into as well. I'll work on submitting a patch for it. It shouldn't be too hard.

Thanks for taking care of this!
