Feature: System notification on failure of test(s)

[reintroducing]

Current behavior:

Test failure shows up in the Cypress app.

Desired behavior:

In much the same way that you can do a Gulp notification using gulp-notify to show a system notification for, perhaps, an ESLint failure, it would be great to also be able to do this with Cypress when a test fails. The use case is running the Cypress app in the background running your tests against your local development environment while you develop. I have Cypress running and every time I save my JS files Cypress silently runs the tests. Unless I click over to the app and see I've broken something, I won't know that a test is failing.

This type of real-time feedback would be huge on every save to catch if you've just caused a regression to happen with your latest changes. I would love it if I didn't have to go back to the app to check if something is failing every time and be notified of this.

Versions

All.

Thanks for opening this issue. We actually did discuss this before and felt this was a great idea. 👍

We would likely implement this through Electron's Notifications

[sainthkh]

We can implement this with node-notifier. But it might mean to bundle some exe files into our electron bundle. While the file sizes are small (<1MB combined), but I cannot be sure if it's OK to add them or not.

jest also uses node-notifier but does not bundle the dependency, instead, when the user starts jest with the --notify flag, it fails and ask the user to install node-notifier as dev dependency.
