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.
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.
Changing the database after the process running the browser has started
is proving to be one of the reasons tests are failing sometimes, so
we're reducing the number of times were that happens. In this case, we
were changing a setting.
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.
By using real XML responses developers will be able to understand better
how the integration works (the data flow), and the correspondency between
`remote_census` settings and their place at a real XML response.
As `stubbed_responses` methods were removed from the model layer now the
stubbing part should be managed from the test environment code so also
added a new helper module `RemoteCensusSetup` that can be used anywhere
where we need to call the web service.
