JSDOM Issue before all" hook: Error: timeout of 2000ms exceeded. Ensure the done() callback is being called in this test.

I was getting
before all" hook:
Error: timeout of 2000ms exceeded. Ensure the done() callback is being called in this test.
For

before(function () {
  this.jsdom = require('jsdom-global')()
})

after(function () {
  this.jsdom()
})

Changing above lines code to import statement below resolved the issue.

import 'jsdom-global/register'; 

Stating here , so in case anybody else encounter the same will have a solution. Thanks!

It looks like you did before(function(done)...) with an argument.

Nope! Just as I have mentioned ..without argument.

before(function () {
  this.jsdom = require('jsdom-global')()
})

after(function () {
  this.jsdom()
})

Alright. Thanks for the report! I'm closing this issue now as it's been resolved. If anyone can replicate the issue, please leave a note.

I just came across the issue as well, it seems initialising jsdom sometimes takes a while, setting the timeout higher solves the issue

  let cleanup: () => void

  before(function() {
    this.timeout(5000)

    cleanup = jsdom('', { url: 'http://localhost' })
  })

  after(() => {
    cleanup()
  })

Weirdly enough, instrumenting it, it only seems to take ~500ms

let cleanup: () => void

  before(function() {
    // this.timeout(5000)

    const start = process.hrtime()
    cleanup = jsdom('', { url: 'http://localhost' })
    console.log(`Loading took ${process.hrtime(start)[1] / 1000000}ms`)
  })

  after(() => {
    cleanup()
  })
