    [#1467375] Use different database for unit & integration testing

Problem:
I wanna push 2nd commit to origin/master so others can benefit from this commit while I work on the blah blah feature

Solution:
- create another branch from local master
- find SHA id of commit to cherry pick
- use git cherry-pick to select 2nd commit into the branch
- rebase into local master
- push to origin/master

git checkout master && git checkout -b upgrade_cucumber_gem
git log 123-feature-blah_blah
git cherry-pick 19651c61957f2b5cab9614948fe68c4fd505da04
git checkout master && git rebase upgrade_cucumber_gem
git push origin master
