When launching cypress in background cy.exec cause chrome to freeze

[freddidierRTE]

Current behavior

On a linux OS using chrome with version cypress version 10.10.0 (pb reproduce with previous versions as well) , node version 14.20.1

Launch cypress in background : ./node_modules/.bin/cypress open &

Execute following test :

describe ('Exec',function () {

  before('Exec', function () {
    cy.exec('ls');
  });

  describe('Basic test', function () {

    it('test ', ()=>{
     cy.visit('');
    })
  })

})

When launching cypress in foreground (./node_modules/.bin/cypress open) it works

Desired behavior

exec works when launching cypress in background

Test code to reproduce

describe ('Exec',function () {

  before('Exec', function () {
    cy.exec('ls');
  });

  describe('Basic test', function () {

    it('test ', ()=>{
     cy.visit('');
    })
  })

})

Hi @freddidierRTE . Thank you for opening an issue. I tried giving this a reproduction here on my ubuntu machine but didn't have any luck reproducing it. Would you be able to work with the reproduction to reproduce this issue for us?

[freddidierRTE]

Hi @AtofStryker , i reproduced it with you test code

New element , if i put back in foreground the task in the shell , it stop freezing and execute the test ,debug logs (see the fg shell command in the log )

I reproduce it as well with the provided electron browser

[AtofStryker]

@freddidierRTE maybe I am missing something. What command in your terminal did you run or did you just one of the provided npm scripts to reproduce?

[freddidierRTE]

Starting from the root of your github repository :

Test 1 :
In the shell :

./node_modules/.bin/cypress open

Launch test via UI

--> works as intended

Test 2 :
In the shell

./node_modules/.bin/cypress open &

Launch test via UI
--> It freezes

Test 3:

In the shell

./node_modules/.bin/cypress open &

Launch test via UI
--> It freezes

In the shell :

fg

--> works as intended

[AtofStryker]

interesting. I gave this a go and wasn't able to get this to freeze but it did crash on me every time I tried to run ./node_modules/.bin/cypress open &

[nemonemi]

I am experiencing this as well with Cypress 12.9.0.
I run it with nx e2e project-e2e (https://nx.dev).
The weird thing is it just started happening.
