Change the URL JSDOM uses for the current page https://jestjs.io/docs/en/configuration#testurl-string Affects all DOM APIs that return information about the URL, for example window.location. Why: We now have tests for setting/deleting cookies. Tough-cookie, the library JSDOM uses for cookie handling cookies doesn't allow setting cookies with `domain=localhost`. This is correct by RFC6265, the standard it follows, as domains must have 2 or more `.`s in them. The only way to set a cookie on `localhost` is to leave out the `domain` attribute. The code we are testing sets and deletes cookies set on specific domains so using `localhost` is out. We also cannot just set/delete cookies on the domains used as cookies are required to match the domain of the current page. The solution we are left with is to set the current page to one from production and make sure each cookie is set relative to that domain. Note: this introduces `testURL` in isolation to be sure it doesn't break any existing tests. 2020-01-22 10:13:37 +00:00			`setupFiles: ['./support/setup.js'],`
pass nextUrl through yubikey flow the next url comes from sign in via a query param, and needs to go to the POST /webauthn/authenticate endpoint. That endpoint logs the user in and returns the redirect to the browser, and will take the next from the request query params to get there. also moving the window mocks to beforeEach/afterEach ensures that promise callbacks from previous tests aren't still associated in future tests to ensure good test isolation. unfortunately i couldn't get mocking location for a single js test to work, but by changing the global config i was able to add some query params that i can expect to be passed through. Don't love this at all but not quite sure of a good way round this. I think we're not practicing very good hygiene and best practices with our mocking and it's really confounding me here. 2021-05-27 12:07:11 +01:00			`testURL: 'https://www.notifications.service.gov.uk/?next=%2Ffoo%3Fbar%3Dbaz'`
