Cypress: Bug: Crash "Error: write EPIPE" when running all specs

Created on 2 Nov 2019 · 19Comments · Source: cypress-io/cypress

Current behavior:

Update:
It also crashes on my Mac now:

Vue 2.6.11
cypress 3.8.3
macOS 10.15.2

When running all of my tests cypress crashes with this error. This only happens on Ubuntu, it does not crash on Mac. It also works if I run it without GUI, Chrome and Electron crash in GUI mode. I have 18 specs file, when I run only one of them it works:

Getting a similar errror, unable to run all tests, but running a test individually works.

Sometimes after running a single test it will let me run all and will complete without error. It's really intermittent so I'm having a hard time offering anything else that will be useful for debugging.

Have you checked where the error ERR_HTTP_HEADERS_SENT might come from?

gabbersepp on 4 Nov 2019

How would I be able to check that? Isn't it from inside Cypress?

lassesteffen on 4 Nov 2019

Good question without knowing your code :-) Have you tried each of the 18 tests isolated? Maybe this error is responsible for the crash.

gabbersepp on 4 Nov 2019

I will try that when I am at my laptop and let you know. 👍

lassesteffen on 5 Nov 2019

I'm also seeing the Error: write EPIPE issues on 3.6 and not on 3.4. I can't exactly narrow it down yet, but I can consistently cause it to happen by attempting to open devtools in the gui while it's GETing all the spec files in the background. Very rarely it'll happen without that. I'm also seeing tests hang somewhat consistently on circleci after they've begun to run with 3.6 and not in 3.4. I don't know if it's a related issue though.

paulfalgout on 6 Nov 2019

I have the same experience:

when all specs are run in headless mode - everything :ok:
when a single suite is run in GUI mode - everything :ok:
but whenever all specs are run in GUI mode, the test runner crashes :x:

Before the crash one or two instances of Error: write EPIPE at WriteWrap.onWriteComplete [as oncomplete] (internal/stream_base_commons.js:82:16) and then two or four instances of Error [ERR_HTTP_HEADERS_SENT] [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client appear in the console.

This is the first time I tried to run the GUI mode since upgrading to 3.6 a few days ago (usually I only use the headless mode).

RadovanBednar on 18 Nov 2019

I can occasionally see this error when running even a single spec in GUI mode :/

I also ran the tests on my machine again, and the single tests work fine, just all of them together seem to crash it for me.

lassesteffen on 12 Dec 2019

Getting a similar errror, unable to run all tests, but running a test individually works.

Seeing this on 3.8.2. As above, tests work individually, headless on CI, but not via the GUI when running all specs.

Forfold on 5 Feb 2020

I found this comment in another issue explaining that "running 'All Tests' from the GUI is not a good idea" and shouldn't be done.

I'm not sure if that's still the case and curious if this is related, but I think we'll move away from running all specs in interactive mode.

If Cypress authors are suggesting not to use the feature, then why does it still exist for end users? 🤔

Forfold on 5 Feb 2020

They discuss that briefly in one of the linked issues https://github.com/cypress-io/cypress/issues/681

This could be solved by removing the Run All Tests button but users would likely complain about this and it's unexpected.

Why can every other testing tool run all tests but Cypress can't?

I can understand the concern about removing the button, not sure if I agree with it, but adding a note to the Docs might be helpful.

rbaxter08 on 5 Feb 2020

I'm also seeing the same error as @rbaxter08

However I actually got it when running a single test. NOT using the "Run all tests" feature. Today was the first time I saw it, but one of my team members was mentioning Cypress crashing as well.

We encounter this problem to. It is very annoying. I would really love to run all tests with GUI.
Single

Test: OK
All Test headless: OK
All Tests with GUI crashes most of the time. Sometimes it works for no obvious reason.
When we see the logging of test loading it looks strange that most of the tests are loaded multiple times:

GET /__cypress/tests?p=tests/e2e/specs/info/kontoloeschen.js-157 200 16.272 ms - -
and later on:
GET /__cypress/tests?p=tests/e2e/specs/info/kontoloeschen.js-618 200 3.318 ms - -
and later on:
GET /__cypress/tests?p=tests/e2e/specs/info/kontoloeschen.js-211 200 17.511 ms - -
and later on:
GET /__cypress/tests?p=tests/e2e/specs/info/kontoloeschen.js-851 200 2.056 ms - -
and so on.. It happens with all test files. Looks strange to me but the behaviour is the same if "run all tests" succeeds.

We are running cypress 4.3 on Ubuntu and when it crashes we get this stack trace:

I also have this error sometimes while I'm running my tests locally in the GUI. Most of the times it happens when I just want to run a single test via the GUI. The browser opens for a second and then it crashes with the error below. This doesn't happen very frequently (not enough to be annoying... yet).

Also the whole Cypress process stops running when this happens and for some reason it also out puts something like this before it stops:

✨  Done in 1954.32s.

So it thinks it is running a test suite or something? 🤔 I was just running single tests while developing.
