cy.writeFile Does Timeout #3350

Current behavior:

The documentation says it is technically possible for cy.writeFile to timeout but it shouldn't, however, it did for me today. I know it was the cy.writeFile that timedout because it is the only cy.Command in my aftereach hook.

The Error Output:

  20) EditAndBranching
       "after each" hook for "Tag And Frog":
     Error: Cypress command timeout of '4000ms' exceeded.

Because this error occurred during a 'after each' hook we are skipping all of the remaining tests.
      at http://localhost:5050/__cypress/runner/cypress_runner.js:66264:25

Desired behavior:

I think Cypress should provide a way to override the timeout or fix it so it can't timeout.

I also think Cypress should not stop running the remaining tests when one fails in the aftereach hook. That is a harsh punishment for an intermittent failure. In fact that also is a good case for not failing all tests in the aftereach since one failure does not necessarily mean they all will fail. Perhaps this needs a rethink as well.

Steps to reproduce: (app code and test code)

"Issues without reproducible steps will get closed." -- How am I supposed to give you code to reproduce this? Do I have to write some OS hook to intercept the writeFile command and make it take longer than 4 seconds?

Sorry but I don't have the time to work up some sort of repro steps...this requirement on obvious flaws is an impedance to filing a bug. I've reported the bug, if you all want to just close and do nothing then so be it.

Was able to reproduce from code below:

it('writes until timeout', () => {
  cy.writeFile('./fixtures/my-long-file.txt', Cypress._.times(900000, '😈'))

This write:file event actually seems to run forever:

Thanks Jennifer, I'm glad you were able to come up with repro steps.
