We have been clearing all the Google Analytics
cookies on each page request.
It is now possible for a user to consent to having
Google Analytics cookies so this should have been
checking for that before deleting them.
This makes that change, with tests for those
scenarios.
Removes the following fields from the tracker
config:
- `name`, which was erroring due to it
including a `.`
- `displayFeaturesTask` which seems to be
deprecated
Also refactors the `create` command to put all
fields into the options parameter, as shown in the
developer docs:
https://developers.google.com/analytics/devguides/collection/analyticsjs/creating-trackers
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.
