Cypress resolves import incorrectly?

Bug

Current behavior:

When two test files import a same module, cypress resolves each import from scratch instead using the same reference. This behavior is different from node/require imports.

Desired behavior:

Cypress should import modules the same as node.

How to reproduce:

cypress/utils.js:

export const key = +new Date()

cypress/integration/test1.js

import { key } from '../utils'

describe('Foo1', () => {
  it('Bar1', () => {
    cy.log(key)
  })
})

cypress/integration/test2.js

import { key } from '../utils'

describe('Foo2', () => {
  it('Bar2', () => {
    cy.log(key)
  })
})

When running all, cypress logs two different keys. The same import in nodejs results the same key.

Cypress serves each spec in isolation - which is the correct and intended behavior.

We are actually moving more towards this way, which will become the default enforced behavior on all runs. You can read more here: #681
