forceable-tty
Sets process.std(in/out/err).isTTY to true basing on env vars.
Usage
Include require('forcable-tty').override();
in your code.
Then you can use FORCE_STDIN_TTY=1, FORCE_STDOUT_TTY=1 or FORCE_STDIN_TTY=1 env variable to get required outcome.
Example
[~/forceable-tty] echo test | ./example/example.js
process.stdin.isTTY: undefined
process.stdout.isTTY: true
process.stderr.isTTY: true
[~/forceable-tty] echo test | FORCE_STDIN_TTY=1 ./example/example.js
process.stdin.isTTY: true
process.stdout.isTTY: true
process.stderr.isTTY: true
