Expose a way to run test in non-interactive mode without defining CI

[etienne-dldc]

Current Behavior

• yarn test start jest in interactive mode
• Setting CI=true start jest in non-interactive mode but without colors because most tools only check wether or not the CI environment variables exist an not it's value:
  https://github.com/watson/ci-info/blob/master/index.js#L53
  Because of this you loose some functionalities, like colors when using tools like np or lerna.

Desired Behavior

Being able to run tsdx test in non-interactive way without setting the CI variable.

Suggested Solution

Using a different environment variable name to disable "auto watch mode":

TSDX_AUTO_WATCH=false tsdx test

Who does this impact? Who is this for?

This impact everyone who was using tsdx test in non-interactive mode outside of a CI.
It would make the migration from 0.11 to 0.12 easier.

ohh.. good point 😬

@jaredpalmer we may have to revert this and just use a watch flag.
