This is possible now we're testing letters and emails separately.
I've added a few missing cases for NHS and non-central branding.
In the next commits we'll look at the remaining special cases.
These all behave the same as each other so there's little value in
testing all of them - if we had 100 org types we wouldn't test them
all, but it's easy to get carried away when there are fewer.
We already had different functionality for email branding and will
soon be adding more for email branding pools.
Note that the "get_available_choices" class method was only used for
email branding - we can do it in the constructor for letters.
Central orgs have more options than others, including the option
to revert back to GOV.UK once branding is set. Combining the tests
together should make that a bit clearer.
All of the mock / UI assertions in these tests are covered by the
tests above them - these tests were mostly targetting which options
were being shown, which we can check at a lower level.
This is much simpler than trying to test the function via the page,
although there are still two scenarios to test there:
- The page with radio buttons (using NHS as an example).
- The page with a text form (using "other" as an example).
In future work we could split this test in two to make it clearer
what it's trying to test. For now, this keeps the diff simple.
