This test is failing often due to an "Unable to autoload constant"
error, that will be fixed after switching to zeitwerk.
Just like it happened in the the "Polls can be listed" test, the reason
seems to be accessing a page containing several ActiveStorage
attachments. However, since this test only makes sense when two or more
images are displayed on the page, we can't change the test so create
just one image.
So, for now, we're commenting the test, and we'll uncomment it again
when we enable zeitwerk in version 2.2.0.
Creating records after starting the browser with the `visit` method
sometimes results in database corruption and failing tests on our CI.
Splitting some tests or merging them together solves the issue.
When running these tests, under certain conditions, we get a warning
followed by an error:
```
activesupport-6.1.7.7/lib/active_support/dependencies.rb:502:
warning: already initialized constant ActiveStorage::Representations
activesupport-6.1.7.7/lib/active_support/dependencies.rb:502:
warning: previous definition of Representations was here
Failure/Error: raise LoadError, "Unable to autoload constant
'#{qualified_name}', expected #{file_path} to define it"
LoadError: Unable to autoload constant
ActiveStorage::Representations::RedirectController, expected
activestorage-6.1.7.7/app/controllers/active_storage/representations/redirect_controller.rb
to define it
```
The error seems to take place when we request a page in a test that
loads two (or more) ActiveStorage images if ActiveStorage hasn't loaded
yet, although it's a flaky error and so the test doesn't always behave
like this.
We've tested that switching to zeitwerk solves the issue but, since we
aren't switching to zeitwerk in version 2.1.1 and we'd like this version
to run all tests correctly, for now we're changing the tests so they
don't load two records with images.
On of these tests ("Polls Index Polls can be listed") fails on my
machine when run individually. I haven't been able to consistently
reproduce the other ones.
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.
Note we're excluding a few files:
* Configuration files that weren't generated by us
* Migration files that weren't generated by us
* The Gemfile, since it includes an important comment that must be on
the same line as the gem declaration
* The Budget::Stats class, since the heading statistics are a mess and
having shorter lines would require a lot of refactoring
The `reload` method added to max_votes validation is needed because the
author gets here with some changes because of the around_action
`switch_locale`, which adds some changes to the current user record and
therefore, the lock method raises an exception when trying to lock it
requiring us to save or discard those record changes.
By using the Rails `button_to` helper (which generates a form), and adapting the
response to `html` and `js` formats, the feature works with or without javascript
enabled.
The extra check to see the voter count has increased was redundant; we
already check the request has finished inside the
`vote_for_poll_via_web` method and we check all three voters are created
in the results table.
Updating the poll so it's in the past after starting the browser might
result in database inconsistencies while running the tests, so we're
using `travel_to` instead.
We weren't showing the details of answers without a description, even if
they had images, videos or documents. Some users found that behavior
unexpected since the description isn't a mandatory field and so they
left it blank, but they added images to that answer and they didn't
appear on the poll page.
Note we had a condition not to show the title of an answer when it had
no description. I think that condition was redundant because answers
without a description weren't loaded in the first place. Anyway, that
condition doesn't make sense anymore because we're displaying answers
with images but no description.
We're not adding the rule because it would apply the current line length
rule of 110 characters per line. We still haven't decided whether we'll
keep that rule or make lines shorter so they're easier to read,
particularly when vertically splitting the editor window.
So, for now, I'm applying the rule to lines which are about 90
characters long.
Checking the database with methods like Activity.last does not test that
the record is present where it should be (first record of the table in
this case). In these tests there's only one record, though, so the order
doesn't matter that match.
However, calling methods like Activity.last generates a database query
after the process running the browser has been started, and this might
lead to inconsistent data.
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.
System tests are used to test the application from the user's point of
view. To test for specific exceptions, particularly regarding
authorization permissions, controller tests fit better.
Another option would be to test the page displayed shows a certain text,
like "Internal server error". I'm choosing controller tests because
they're faster and we're basically testing the same scenario many times
and we've already got a test checking what happens when users access a
page raising an exception.
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.
After updating foundation-rails in commit 58071fd6, the orbit slider
stopped working properly. That's because the `.orbit-slide` elements now
use a `position: absolute` rule, and so our rule for `.orbit-container`
elements making their height 100% (which we added in order to be able to
add images with different heights) makes them have a height of 0px,
since now the `.orbit-slide` elements are not part of the document flow
anymore.
Making the `.orbit-slide` elements have relative position fixes this
issue, but introduces a different one, producing a really bad-looking
animation when changing a slide.
So we're disabling the animation as well in order to avoid this jump.
This change also fixes another issue introduced in commit 58071fd6 which
caused slide controls to stop working when changing slides back and
forth.
