I haven't found an elegant way to remove them, but since they were the
only three variables left out of 383 we used to have, I can live with
this low percentage of inelegant solutions.
There's a very common pattern in our test, where the setup only has two
lines:
variable = create(:something)
unused_variable = create(:something_else, something: variable)
In this case, since there's a blank line below these ones and then we'll
get to the body of the test, and the second variable is going to be
created based on the first variable, we can remove the useless
assignment and the readability is still OK.
Another option we almost unanimously discarded was:
variable = create(:something)
_unused_variable = create(:something_else, something: variable)
We don't use it anywhere else, either.
One more option we considered but found a bit too much for simple tests:
variable = create(:something) do |something|
create(:something_else, something: variable)
end
Then of course we could move the setup to `let` and `before` blocks, but
the tests could get over-structured really quickly.
These feature tests were taking too long, we can't run them for every
single model.
I'm taking the approach of using one different model for each test, but
in theory only using a few models covering every possible scenario
would be enough.
The `type: :feature` is automatically detected by RSpec because these
tests are inside the `spec/features` folder. Using `feature` re-adds a
`type: :feature` to these files, which will result in a conflict when we
upgrade to Rails 5.1's system tests.
Because of this change, we also need to change `background` to `before`
or else these tests will fail.
We needed to bring back support for CKEditor in our translatable form,
which we had temporarily remove.
And now we support CKEditor in our translatable specs, and so we can
remove the duplicated specs for poll question answers.
