These variables can be considered a block, and so removing them doesn't
make the test much harder to undestand.
Sometimes these variables formed the setup, sometimes they formed an
isolated part of the setup, and sometimes they were the part of the test
that made the test different from other tests.
In the scenario where we want to test scopes and use `match_array`, we
usually declare variables we never use, which raises a warning in the
Ruby interpreter (since the main cause for an unused variable is a
typo).
So I've decided to just split the tests into cases where every record is
returned and cases were no records are returned, just like we do in
other places.
There are several other options we've considered:
1. Don't declare unused variables, but declare the ones we use
2. Prefix unused variables with un underscore
3. Declare just one variable being an array containing all elements, and
access the elements using Array#[]
4. Don't declare any variables, and compare results against attributes
such as titles
None of these options was met with enthusiasm.
We're using `eq` and `match_array` in most places, but there were a few
places where we were still checking each element is included in the
array. This is a bit dangerous, because the array could have duplicate
elements, and we wouldn't detect them with `include`.
The group is automatically assigned when we assign the heading. The
budget isn't needed either, except for a special case related to the
reason to be rejected.
We were creating the investments with more ballot counts first in every
test, so the tests would pass if we ordered the investments by creation
date instead of ordering them by the number of ballot lines.
So now we test in depth at the model level, and can be a bit more
relaxed about integration tests for translations.
Note we're defining some extra factories to make sure all translatable
attributes with presence validation rules are mandatory. This way we can
simplify the way we obtain required fields, using `required_attribute?`.
Otherwise, fields having an `unless` condition in their presence
validation rules would count as mandatory even when they're not.
This is a mistake I made in commit f2ef27d3. Back then I thought we
needed to keep Globalize.locale and I18n.locale in sync, but the truth
is it automatically happens when setting Globalize.locale to nil.
So now we can use I18n.with_locale (at least in the tests) and forget
about Globalize, which will make it easier to switch to Mobility in the
future.
Now factories define default headings for investments, so there's no
need to create a group and a heading to create an investment.
Likewise, in order to create a heading it isn't necessary to specify a
group anymore; specifying the budget is enough.
It's possible that there are more similar cases we haven't simplified
yet; I'm only addressing the obvious ones.
Investments can be reclassified to a different heading during the participatory budget process.
Whilst we are recording this change of heading in the `previous_heading_id` attribute, we are only keeping the _last_ heading. If there are multiple reclassifications we lose this chain of reclassifications.
In this commit we are adding an `original_heading_id` attribute, that will only be set once, when creating the investment, and will not get lost with multiple reclassificaitons of an investment.
We don't need to create a heading every time we create an investment; we
can use an existing one by default.
Some tests are now much faster and don't fail on Travis due to reaching
Capybara's timeout anymore.
As we cannot order budget investments by any translatable field through
AR queries we are doing the same using ruby Array sort method and doing
array pagination manually with Kaminari 'paginate_array' helper method.
Results were not including records without translations for current
locale (I18n.locale). Now we search for given title against all
translation fallbacks for current locale.
Also fix sort_by_title method [1]
[1] Use ruby sort instead of active record order scope because Globalize
does not provide a way to search over all available fallbacks when
translation for current locale does not exist.
