The specfiles are truncated in the stdout results of a run, making it difficult for users to track down which test file results they are looking at.

Some suggestions
Cypress 3.4.1
Please do that. I want to format the output to the console myself.
I wonder if we could get away with the following (simple) solution:
if the filepath is longer than let's say 20 characters, print it by itself on the first line and then print the rest of the stats on the second line for each spec.
By the way, this reporting is done not in the CLI NPM module but in packages/server in file https://github.com/cypress-io/cypress/blob/develop/packages/server/lib/modes/run.coffee
Hey team! We need it badly... lets make it happen! :)
The code for this is done in cypress-io/cypress#5120, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
Released in 3.5.0.
