Possible infinite loop while running in Jenkins with retries

[vidarc]

Current behavior

While running Cypress with a docker image inside Jenkins, we are currently encountering an infinite loop (or what appears to be one). Seems related to this issue: #9040, but I am still encountering the problem with versions 6.3.0 and 6.4.0 of cypress.

With DEBUG=cypress:* set, I get these two messages repeatedly until I either abort the Jenkins build or lerna crashes.

cypress:server:browsers:electron debugger: sending Page.screencastFrameAck with params { sessionId: 1 }
cypress:server:browsers:electron debugger: received response to Page.screencastFrameAck: {}

Appears to be related to retries, as it can successfully run occasionally, and I've seen that when it does pass all tests, the tests ran quickly with no retry attempts.

Desired behavior

Test code to reproduce

Unfortunately, I can't share my code, but can try and provide any more information you need.

Versions

Issue exists in 6.2.1, 6.3.0, and 6.4.0 at minimum. Haven't heard of or seen this issue from previous versions.

The debugger lines are just normal activity that happens when a run is running - so it's likely hanging.

• Does the hanging go away when you remove test retries?
• Can you provide any of your configuration? cypress.json?
• When did the hanging begin? Was it always hanging?
• Does it hang locally? Does it hang when running in --browser chrome?
• Any way to reproduce - a simplified example or pseudo code of what you're doing.

There's really nothing we can do without a way to see the hanging on our side. So as much information you can give for us to get there would be helpful.

I am experiencing the same issue running Cypress in an Azure DevOps pipeline. The pipeline runs over 330 tests, and we were experiencing hangs 8-10 minutes into the testing cycle which would eventually cause the task to timeout. After reading issue 9040 I tried upgrading to 6.4.0 which helped, allowing the tests to run to longer, but it did not alleviate the issue. I added the cypress_failed_log plugin and could clearly see the issue was hanging on retries as the tests progressed.

Our initial retry setting was 3 in cypress.json. Setting this down to 2 allowed the tests to proceed further, and with a setting of 1 we were able to complete the entire test suite.

Tests are running headless using electron in a Linux VM.
Cypress version 6.4.0
336 tests run, 69 failures

Here is the log output of the start and finish when running 6.0.1:

Again, setting retries to runmode 1, openmode 1 allowed the test cycle to complete. Hope this info helps!

We're experiencing the same in two projects using Cypress 6.5.0

• I can confirm that the issue only arises when retries are enabled
• Retries generally seem to work - it's not that it would always happen when a retry kicks in
• The issue appears intermittently, but I found no way to force or reproduce it
• I have not yet seen the issue locally
• Just from the log output, I can see some patterns. It seems to happen during the same set of tests. We do have some flaky tests, but the ones hanging when retries are on don't match the ones being flaky when retries are off. It sometimes happens before a test has started to run, sometimes during. Sometimes when all tests in a suite have run, sometimes during
• The recorded videos of a failed run seem to be corrupted. The files are present, but they can't be opened
• The projects both have a service worker
• The servers are protected with basic auth
• We have a React / Next.js application
• We run on circleci with x-large instances (8 vCPU / 16 GB) and have parallelization on

Could just be a coincidence, but service worker is heavily used in my application as well.

This looks similar to #9040 based on which some fixes were made with #14381, which was released in 6.2.1

Yes, it does sound the similar as #9040, but all of us who have run reported the problem here are using 6.4 or greater and are still seeing the issue.
Can somebody provide some more help to resolve this issue?

the docker image we are using to run cypress on jenkins was installed with node 14, while the node version included with cypress is 12 and i saw that cypress currently only supports 10/12, is there a potential issue there? unsure how much cypress uses that built in

[vidarc]

found this: badeball/cypress-cucumber-preprocessor#476

seems the likely culprit. i am using the cucumber plugin as well

same issue: cypress 6.8.0, no retries set (no retries setting defined which means 0), sometimes cypress hangs when running on dev.azure (we're never experiencing the same behavior locally)

the log always ends with these repeating lines:

cypress:server:browsers:electron debugger: received response to Page.screencastFrameAck: {}
cypress:server:browsers:electron debugger: sending Page.screencastFrameAck with params { sessionId: 1 }
...
cypress:server:browsers:electron debugger: received response to Page.screencastFrameAck: {}
cypress:server:browsers:electron debugger: sending Page.screencastFrameAck with params { sessionId: 1 }

until CI cancels the job due to timeout

I just want to chime in and say that we too are experiencing the same issue, however, we're experiencing it in all environments.

I have already commented on a similar issue thatp proposed some changes:
#8206

We are experiencing this stall in 70% or more. This means, rerunning CI several times for every change to go through. I am not sure how to debug or address this issue further.

Our Setup

• Cypress 6.8.0
• React & Node with Typescript
• We don't have retries enabled
• we are using nx.dev for our monorepo.
• "only" 9 test files, which usually complete in 3 minutes.
• Authentication via OAuth

Things we have tried so far

1. Run garbage collection between tests: Reduce Memory Usage with window.gc() #8525
2. Increase the CI container by 4x (to 16gb ram) - it used to even run with 4gb of ram in ci
3. Switch from electron to chrome
4. Set "numTestsKeptInMemory": 0
5. Disable video recording
6. Updating to Cypress 7
7. Running every test file individually

None of which seems to help.

This issue has not had any activity in 180 days. Cypress evolves quickly and the reported behavior should be tested on the latest version of Cypress to verify the behavior is still occurring. It will be closed in 14 days if no updates are provided.
