"As Node.js continues to gain adoption, there is an increasing
need for tools to help test the applications built on it. When
cloud hosting provider Rackspace started to use Node.js and ran up
against the testing requirement, they wrote their own testing tool
for Node.js applications called Whiskey.
Whiskey is an open source test automation stack that Rackspace
is using within its own infrastructure. Although Rackspace
officially announced the Whiskey project only this week, the
company has been using it internally for nearly two years. Since
its inception, the project has also been open source.
