Get Passed Failed Count After running all feature Files and do some post Actions.

[rahulkedia1409]

Hi,
I am having an requirement as in:-
I have 10 feature files each containing one scenario, and i am currently using 2 instances of the chrome browser.

1. I want to collect passed failed counts of the total scenarios run and get a consolidated passed failed count when all the feature files have finished running.
2. Now when my all feature files have run want to do perform a post action let's say use this passed failed count and send it on slack channel(slack api i can hit and write the relevant code).
   .........

Facing problem in getting the counts (Tried with singleton but it dosen't seems to work).
And if i get the counts how to call a post task to do the needful. Any Ref. will be helpful. Thanks in advance.
