e2e testing – Cypress pipe console.log and command log to output

As of Cypress 3.0.0, you can use cy.task() to access node directly and output to the node console. From the docs:

// in test
cy.task(log, This will be output to the terminal)

// in plugins file
on(task, {
  log (message) {
    console.log(message)
    return null
  }
})

See here for more info.

I dont know of a way to mirror the Cypress logs to the console directly, but this is at least a workable alternative.

Setting the ELECTRON_ENABLE_LOGGING environment variable to 1 will cause all Chrome internal logging to be printed to the console.

ELECTRON_ENABLE_LOGGING=1 npx cypress run

ELECTRON_ENABLE_LOGGING

Prints Chromes internal logging to the console.

With this enabled, in addition to capturing any existing logging, this will also allow you to manually log within a test using console.log:

console.log(Response JSON:  + json)

Expanding on @Joshua-wades answer, you can overwrite cy.log to redirect all calls to it to the log task. Just as the following:

Cypress.Commands.overwrite(log, (subject, message) => cy.task(log, message));

Note: theres a small drawback to this: when you run the test using the Test Runner, instead of seeing LOG my message in the command log, youll see TASK log, my message. But IMHO its negligible.
