Cypress should fail if no spec files are found

[bahmutov]

• Cypress Version: 0.19.2

feature

Current behavior:

Imagine you have no spec files for some reason. cypress run will happily report 0 tests and will finish with exit code 0

Expected behavior:

Having nothing to run is a sign of misconfiguration / missing files. Cypress should error if there are no spec files.

This situation can also occur if the browser crashes out of memory - I had a OOM crash which didn't crash cypress somehow, causing there to be 0 tests run an a successful build.

cypress run now throws an error immediately when no spec files are found.

$ cypress run
Can't run because no spec files were found.

We searched for any files inside of this folder:
