Bug

Current behavior:

In a Docker environment when running cy.exec('echo test') with a multi word command the following error is produced

> "spawn echo test ENOENT"

while cy.exec('echo') or cy.exec('ls') do not fail.

Perfect, @andreaazzara thank you so much for taking time to report this. We will address this.

Funny you should bring this up. Internally we switched all of our CI containers to docker and I actually fixed this bug yesterday.

You'll see it go out in the next release 0.20.0.

The code for this is done, but this has yet to be released. We'll update the issue and reference the changelog when it's released.

Fixed in 0.20.0
