For the HashAlignment rule, we're using the default `key` style (keys
are aligned and values aren't) instead of the `table` style (both keys
and values are aligned) because, even if we used both in the
application, we used the `key` style a lot more. Furthermore, the
`table` style looks strange in places where there are both very long and
very short keys and sometimes we weren't even consistent with the
`table` style, aligning some keys without aligning other keys.
Ideally we could align hashes to "either key or table", so developers
can decide whether keeping the symmetry of the code is worth it in a
case-per-case basis, but Rubocop doesn't allow this option.
We used "retire" because we translated it literally from the Spanish
verb "retirar" which can mean both "retire" and "withdraw".
Note we're still using "retire" in database fields and method names;
changing that might make it harder to upgrade from a previous version of
CONSUL.
We were updating the database after starting the browser to emulate the
behavior where a user logs in a day before the current request. We can
use `current_sign_in_at` instead and devise will automatically copy that
value to `last_sign_in_at` after users visit a page.
This way we avoid setting up the database after the process runnin the
browser has been started.
JavaScript is used by about 98% of web users, so by testing without it
enabled, we're only testing that the application works for a very
reduced number of users.
We proceeded this way in the past because CONSUL started using Rails 4.2
and truncating the database between JavaScript tests with database
cleaner, which made these tests terribly slow.
When we upgraded to Rails 5.1 and introduced system tests, we started
using database transactions in JavaScript tests, making these tests much
faster. So now we can use JavaScript tests everywhere without critically
slowing down our test suite.
Content like lowercase letters with `text-transform: uppercase` or
spaces after elements with `display: block` or "You're on page:" are not
seen that way by users with a browser supporting CSS.
So we're testing what most users actually experience.
Using separate tests to check every link on the page made the tests
slower. We were also adding a useless initial request on tests which
started by visiting a different URL.
This useless initial request meant in some tests the browser was started
before using factories to create data. Accessing the database in the
test after the browser starts might cause concurrency issues in
JavaScript tests.
Using `<a>` tags with no `href` means these elements cannot be activated
by keyboard users, so we're replacing them with buttons.
In the future we probably want to add more consistency so all toggle
buttons use the same code. We might also add styles depending on the
`aria-expanded` property.
