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.
Just like we did in commit 0ec8878db, we remove the useless initial
request in the `before` filter since most tests started by visiting a
different URL.
We also reduce the risk of database inconsistency which comes with
setting up the database after the browser has been started.
The test was hanging sometimes on my machine, probably because we
weren't making sure the request submitting the form had finished before
visiting a new page.
In theory the spec should have been fine from a technical point of view:
since submitting the form generates a regular HTTP request (and not an
AJAX one), Capybara/Selenium/Chromedrive should wait until the request
is finished. But that doesn't seem to be the case 100% of the time;
maybe conditions change depending on previous tests.
On the other hand, from a design point of view, the spec wasn't that
fine. The main purpose of system specs is to test the way users interact
with our application, and users don't click a button and immediately
visit a different page. Instead, most users wait until they receive
feedback of their actions, and then they visit a different page.
Of course some users might visit another page without waiting. What
happens then cannot be predicted (it will depend on which request is
handled first), and so there's no point in writing a test for this case
unless there's a specific concurrency issue we'd like to check.
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.
We've had to add a couple of hacks in order to make jQuery UI datepicker
work with Turbolinks, and one of our tests is failing because the
datepicker changes its height when changing from a month with 5 weeks to
a month with 6 weeks.
We could add a workaround so the test still passes (jQuery UI doesn't
provide a configuration option to always displays 6 weeks in the
datepicker), but I think it's easier to just use the HTML5 native date
input field, which also allows us to simplify the code a bit and IMHO it
improves the user experience, particularly when using mobile phones.
Since date fields are not supported in Safari and Internet Explorer,
we're still using the jQuery UI datepicker on those browsers (and on any
other browser not supporting date fields).
Due to these changes, we're moving the tests checking datepicker's
behaviour to the dashboard. I've choosing not to change the public pages
because I'm not 100% sure everybody would like this change (some people
prefer the datepicker because we can configure the way it looks).
