While testing for accessibility issues (in a development branch), we're
removing Turbolinks and monkey-patching the behavior of the `click_link`
method to check the page for accessibility issues after each request.
However, we were getting false positives when clicking links that act
like buttons.
So, for the reasons mentioned in commit 5311daadf, we're replacing the
link to delete a document with a button.
This rule was added in rubocop-capybara 2.19.0. We were following it
about 85% of the time.
Now we won't have to check both have_css and have_selector when
searching the code.
Quoting usability experts Jakob Nielsen and Anna Kaley [1]:

There are many examples of this situation. For example, some people
(myself included) configure their browser so it downloads PDF files
instead of opening them in the browser. In this situation, a new tab is
opened, a blank page is displayed, the file is downloaded, and then
either the tab is closed or the blank page needs to be manually closed.
The end result is really annoying.
Other situations include people who use a mobile phone browser, where
navigating through tabs is generally much harder than doing so on a
desktop browser.
But IMHO the most important point is: every browser already provides a
way to open "regular" links in a new tab, so people can choose what to
do, but if we decide to open the link in a new tab, we take control away
from them, and people who'd like to open the link in the same tab might
feel frustrated.
In these cases, the links either say "download" or include the word
"PDF", so people know in advance that they're going to download/open a
PDF file, and so we're giving them information and, by removing the
`target` attribute, we're giving them control over their browser so they
can choose what's convenient for them.

We were displaying documents in five places, and in five different ways.
Sometimes with the metadata in parenthesis after the title, sometimes
with the metadata below the title, sometimes without metadata, sometimes
with an icon in front of the document, and sometimes with a separate
link to download the file.
So we're now displaying the same thing everywhere. Not sure whether this
is the best solution, but at least it's consistent.
We aren't unifying the way we display a list of documents, though, since
different sections look pretty different and I'm not sure whether the
same style would look well everywhere.
Note that we're renaming the `document` HTML class in the documents
table to `document-row` so the styles for the `document` class don't
apply here.
While in unit tests it's great to have different tests for different
expectations, system tests are slow, and so it's better to have just one
test for all the expectations related to the same actions.
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.
We were repeating the same code over and over (with a few variants) to
setup tests which require an administrator. We can use a tag and
simplify the code.
