When launching cypress in background cy.exec cause chrome to freeze #24255

Open freddidierRTE opened 2 years ago

freddidierRTE commented 2 years ago

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 commented 2 years ago

I reproduce it as well with the provided electron browser

AtofStryker commented 2 years ago

@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 commented 2 years ago

Starting from the root of your github repository :

Test 1 : In the shell : 

./node_modules/.bin/cypress open

Launch test via UI

image

--> works as intended

Test 2 : In the shell 

./node_modules/.bin/cypress open &

Launch test via UI --> It freezes

image

Test 3:

In the shell 

./node_modules/.bin/cypress open &

Launch test via UI --> It freezes

In the shell : 

fg

--> works as intended

AtofStryker commented 2 years ago

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 commented 1 year ago

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.
