Cypress pipe console.log and command log to output

Question

Is it possible to redirect or capture Cypress browser log and command log to output?

I read some Cypress github issues on this topic. But I don\'t know how to make

Answer 1

FYI:

Cypress community is going to provide native support so that we don't have to do any workarounds to print the logs on non-GUI(headless) CLI.

Answer 2

Expanding on @Joshua-wade's 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: there's a small drawback to this: when you run the test using the Test Runner, instead of seeing LOG my message in the command log, you'll see TASK log, my message. But IMHO it's negligible.

Answer 3

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 don't know of a way to mirror the Cypress logs to the console directly, but this is at least a workable alternative.
