.not not exposed

playwright-core: ^1.7.1
playwright-expect: 0.3.0

I am trying following code per documentation

await expect(page).not.toHaveSelector("#foobar", {
  timeout: 1 * 1000
})

However I get following error:

    TypeError: Cannot read property 'toHaveSelector' of undefined

      11 | 
      12 | export const isWidgetMessageHidden = (page) => {
    > 13 |   return expect(page)
         |          ^
      14 |     .not
      15 |     .toHaveSelector(selectId(REFERRAL.WIDGET_MESSAGE))
      16 | }

Logging shows below:

console.log(expect(page));

/* returns below, missing not method
    {
      toHaveText: [AsyncFunction: toHaveText],
      toEqualText: [AsyncFunction: toEqualText],
      toHaveSelector: [AsyncFunction: toHaveSelector],
      toEqualValue: [AsyncFunction: toEqualValue]
    }
*/

Am I missing something? Many thanks for these great helpers!

@maxime-helen seems like that you are using expect-playwright without jest, so this is expected behaviour.

I was importing expect straight from test script, called with jest CLI. Configuring my jest.config.js instead with setupFilesAfterEnv: ['expect-playwright'] fixed the problem! Thanks!
