Answer 1

Diagnose :

Theres nothing wrong with the code, I get the following output : (OS : ArchLinux)

  add: two numbers add correctly

    ✔ should be equal


  total:     1
  passing:   1
  duration:  14ms

Its probably a problem with Windows 7 Git Bash Shell

I read somewhere : sending output through a pipe is broken with Git Bash

To discard it run the following command :

node -p -e "Boolean(process.stdout.isTTY)"

For it to work you need the following output : true

Solution (for Windows):

$ node -p -e "Boolean(process.stdout.isTTY)"
false

Using the winpty tool, it creates a hidden console and marshals I/O between it and Cygwin/GitBashshell emulated pty :

$ winpty node -p -e "Boolean(process.stdout.isTTY)"
true
