Jest-puppeteer: Reset browser state between tests?

[testerez]

Hello, I noticed that the state of the browser/page remains between tests (it).
AFAIK the common practice is to have each it independent so running a single it or all of them are guaranteed to give the same result.

I can imagine though that one could want to execute multiple it to cover a single scenario with a describe. So I'm curious to know if the current behaviour is actually intended.

I prefer to let the user decide, you can put a "before" or a "beforeEach" and reset what you need.

Could you show an example of how to reset the page between tests?

Is it sufficient to just do:

beforeEach(async () => {
  await page.close();
  page = await context.newPage();
});

It looks like different things are setup on page based on settings.

It seems like it would be easier to have a setting in jest-puppeteer.config.js that will reset page with the same configuration between tests.

Or maybe provide a jestPuppeteer.resetPage() function that could easily be called to reset to the same configuration?

@UziTech yes I think it is a good idea, can you open another issue to describe the feature?
