Real-Time code coverage in NodeJS app using Atom

Here is my current dev environment on Atom's Editor where I am able to have quasi-real-time (i.e. in about 1s to 2s) feedback on the test executed and its code coverage

For example here is what I see when there is a test failing:
  • note the red dots on the left (after line 44)
  • note the error message right (where '1.2' is not'1.3')
  • code coverage is at 92.50%


And here is what happens when I fix it:
  • Note all dots are now green (on left)
  • Terminal shows details of tests executed
  • Code coverage is now 100%
