When the user clicks ‘GOV.UK Notify’ in the header, they should, by
default, be redirected to the dashboard for their service. They should
only see the ‘Choose service’ page if they have multiple services.
This also allows some logic to be factored out of the template, so one
route now handles all this redirection.
In the future we might want to keep the last-used service in the
session, and always redirect to that. But for now, this should fix most
of the confusion for first-time users.
Because the redirect after logging in checks the number of services a user has,
this now needs to be mocked.
Right now this means adding `mock_get_login` to any tests that need a login.
This must be one of the first mocks, so that it can be overridden by any use
of `mock_get_services`, for tests that specifically want to rely on a quantity
of mocked services, or their contents.
This is a bit fragile, but there’s already a TODO in the code to make it better
so ¯\_(ツ)_/¯
Because a user can have multiple services, they need a way to navigate between
them. Normally they can use the ▶ Switcher to do this, except when:
- they first sign in
- they are on a page which isn’t associated with a service (eg user profile) in
which case we can’t use the switcher because it won’t know what the ‘current’
service is
So this commit adds a new page with a (fake) list of services.
