In order to reduce the code used to add styles to the buttons,
we removed the classes that had been added and handled it with
the new aria-pressed attribute
This rule was added in rubocop-rspec 2.12.0, and we were already
following it most of the time.
However, the rule isn't working correctly in some cases, such as input
selectors, so we aren't enabling it.
Defining a behavior on hover means making it different for people using
a keyboard or a touchscreen (most of the population, nowadays).
In this case, we had an accessibility issue where the message wouldn't
disappear once it appeared. That meant that, after tabbing through all
the links and buttons in, for instance, the debates index, the page
would be filled with "participation not allowed" messages, and in order
to see the information about how many people have voted, reloading the
page was required.
For touchscreen users the behavior was similar to what we get on hover,
although we've found some inconsistencies when trying to support several
elements on the same page.
We think in proposals it makes sense to hide the "support" button when
users click on it, and the same applies to the buttonsto support and
vote investment projects. However, we aren't hiding the buttons to
agree/disagree with a debate in order to keep the information about the
current number of people agreeing and disagreeing visible.
Note we're removing some support spec methods because after these
changes the duplication isn't as obvious as it was in the past.
Hovering over the votes showed a "participation not allowed" message
which was annoying when scrolling with the browser or simply moving the
mouse around the page. Furthermore, it hid the information about the
number of votes, links to show/collapse replies, ...
We're planning to change the behavior of all the "participation not
allowed" messages in order to show them on click instead of showing them
on hover (just like it's done on touchscreens). In the case of comments,
supports, however, there's very limited space in the part showing the
number of supports for comments, so adding this message without breaking
the layout is challenging.
So, for now, we're simply redirecting unauthenticated users to the login
page. If find an easy way to implement a better user interface in the
future to display the "participation not allowed" message, we might
change this behaviour.
This way we can make the view code a bit easier to read.
We're also changing the order of the conditions a little bit so we only
check for the presence of a current user once.
To make sure we aren't breaking anything with these changes, we're
adding some tests. We're also replacing one system test checking content
with a component test, since component tests are much faster.
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.
