CLI - Browser doesn't close and hangs forever

[venu]

Current behavior:

DEBUG=cypress:* ./node_modules/.bin/cypress run  --spec "cypress/integration/test_spec.js" --headed

When test is finished, browser is supposed to close and move to next testsuite. But it hangs forever.

Desired behavior:

When test is finished, browser is supposed to close and move to next testsuite. But it hangs forever.

Steps to reproduce: (app code and test code)

App Code

function onButtonClick() {
   window.location.hash = '/test/new'
}

Test Code

cy.visit("/#/test");
cy.get('.test-btn').click()
cy.hash().should('eq', '#/test/new')

Versions

Cypress - 3.2.0
OS - Ubuntu 18.04

It looks like, its related to onbeforeunload event.

For now, I have fixed this by disabling onbeforeunload after test finished, so browser can close.

afterEach(function() {
  cy.window().then(win => win.onbeforeunload = undefined);
})
