We were always passing `officer.user` to this method, so we might as
well pass the officer (since the "officer" is in the name of the method)
and call `officer.user` inside the method.
We're also calling `login_through_form_as` in order to remove the
duplication between these two methods.
As mentioned in the previous commit, checking the database after
starting the browser with the `visit` method sometimes results in
database corruption and failing tests on our CI due to the process
running the test accessing the database after the process running the
browser has started.
IMHO this is also a bad practice for system tests, since these tests
should be checking what users experience.
In this case, however, I haven't been able to test the user
experience since it looks like booths and officer assignments for voters
aren't shown anywhere.
So, since the purpose of the test was to check the database, and there
are other tests checking what happens after clicking the "Confirm vote"
button in the user interface, we're converting this test into a
controller test.
As mentioned in commits like a586ba806, a7664ad81, 006128da5, b41fbfa52
and c480cdd91, accessing the database after starting the browser with
the `visit` method sometimes results in database corruption and failing
tests on our CI due to the process running the test accessing the
database after the process running the browser has started.
IMHO this is also a bad practice for system tests, since these tests
should be checking what users experience.
In these cases, however, I haven't been able to test the user
experience. For example, it looks like failed census calls for
unregistered users aren't displayed anywhere and can only be accessed by
manually checking the database. Similarly, there's no interface showing
that all the options from a poll have been deleted (which makes sense,
since we only display options in the context of their poll) or a place
showing the responsible name for a proposal.
So we're splitting the tests in two, with the controller test running
the database checks.
We were doing it most of the time, but in some cases we were clicking
the "Sign out" link instead. These actions aren't the same, just like
using `login_as` is not the same as visiting the sign in page and
submitting the form.
Some of these tests failed sometimes because the user wasn't signed in
after using `login_as`. One possible cause could be that we weren't
adding an expectation after clicking the "Sign out" link.
So using `logout` adds consistency, simplifies the code, and might
reduce the chance of these tests failing in the future (although they
might still fail in the future because some of these tests check the
database after a `visit` call).
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
This test will fail if the ID of the created record is the same as the
ID of the first user we create in the test. The chance is very low due
to the `rand(9999999)` which causes the test to fail just once every ten
million times. However, why assigning the ID in the first place? Without
it, the test will never fail due to conflicting IDs.
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.
