xvfb-maybe
This package runs an arbitrary executable / args under xvfb-run if the
platform is Linux and DISPLAY isn't set. This is super useful for making
Electron unit tests run correctly in CI environments while still working
locally
Usage:
## On Windows or OS X, this just invokes electron-mocha ## On Linux, if we are in a headless environment, this will be equivalent ## to xvfb-run electron-mocha ./test/*.js xvfb-maybe electron-mocha ./test/*.js
