Bob Long will demonstrate how to integrate with blink(1) USB devices (https://blink1.thingm.com/) and use them as a status indicator for unit tests using Hspec.
Topics we'll cover:
• Interacting with the shell using Shelly (http://hackage.haskell.org/package/shelly)
• Unit testing with Hspec (http://hspec.github.io/index.html)
• Hole-driven (https://wiki.haskell.org/GHC/Typed_holes) development
