@kingbuzzman, can you explain the motivation in the PR body, also addressing the relation to PR #100, please?`And rebase your feature branch, so that the PR can be merged. Thank you!

EDIT Also, is this an alternative solution to #123? Will it make that PR obsolete?

[kingbuzzman]

@bittner thanks for your reply. I was looking for your input over at the issue

can you explain the motivation in the PR body, also addressing the relation to PR #100, please?

Adds the ability to add a custom Django facing TestRunner, this is different from #100 that changed the behave's TestRunner -- two different test cases.

Also, is this an alternative solution to #123? Will it make that PR obsolete?

Yes, and yes?? Depending on which solution you prefer; I personally have an issue with #123.. I don't know if you do too. If @rodrigondec changes his approach to be more in line with how this is normally done, I have no issue supporting #123

@kingbuzzman Please don't forget to rebase your branch. There are conflicts which don't allow me to merge your changes.
