Logging

There's still no native support for Capture + Display all logs for everything that happens in Cypress There are work-around plugins though:

• cypress-debugger
• cypress-terminal-report
• cypress-log-to-output
  • only works on Chrome. But chrome headless does not work and does not support video recording
  • Can't make it work with electron: Warning: An unsupported browser family was used, output will not be logged to console: chromium

Use DEBUG env var

• See Troubleshooting:Print DEBUG logs
• For electron browser DEBUG=cypress:electron
