We have a `client_request` fixture which does a bunch of useful stuff
like:
- checking the status code of the response
- returning a `BeautifulSoup` object
Lots of our tests still use an older fixture called `client`. This is
not as good because it:
- returns a raw `Response` object
- doesn’t do the additional checks
- means our tests contain a lot of repetetive boilerplate like `page = BeautifulSoup(response.data.decode('utf-8'), 'html.parser')`
This commit converts all the tests which had a `client.login(…)`
statement to use `client_request` (which is already logged in by
default).
Subsequent commits will remove uses of `client` in other tests, but
doing it this way means the work can be broken up into more manageable
chunks.
The page_header macro includes an optional back link. Since the
page_header is always used inside `<main>`, where the back link should
not be, this stops setting the back link in the page header and instead
sets it in the new `backLink` block.
The Design System has standardised on back links being at the top of the
page, decorated with a small text-coloured arrow.
I think this makes more sense than having them at the bottom, because it
suggests, in some way, being able to go back before commiting to any of
the forms on the page. Whereas the things at the bottom of the page
should be performing actions on what’s in the page.
The reason for making this change now is that it de-clutters the area
around the green buttons. This was presenting a design challenge where
multiple levels of interaction were happening in the same form. Moving
these back links to the top of the page should mean that, in these
complicated forms, there’s one fewer thing to compete for the user’s
attention.
I’ve componentised this into a `page_header` macro so that the change is
easier to roll out and maintain.
