The Rakefile and config.ru files are now included by default, and the
behaviour of `Include` changed in Rubocop 0.56.0 (see rubocop's pull
request 5882) so now it **only** includes the files defined there, while
in the past it included those files in addition to the default files.
Using Date.today and Time.now is a common mistake which might lead to
obscure bugs. Now we're making sure we'll receive a warning when a pull
request uses these methods.
The reason for this rule is similar to dynamic factories: we want
dynamic dates to be evaluted relative to the current time, and not
relative to the moment the application was loaded.
Factory bot has stopped supporting dynamic attributes, and we'll have to
change all factories before upgrading.
In order to apply the rubocop rule, we need to bump rubocop-rspec to its
latest version.
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're also adding a rubocop rule so we dont' accidentally add these
keywords again.
We forgot to add these changes to pull requests which were in
development before we upgraded to Rails 5.
We're also moving the rubocop rules to the basic files, so we're
notified when we inherit from `ActiveRecord::Base`.
This cop is necessary so the `Layout/IndentationConsistency` cop works
properly when its `EnforcedStyle` is set to `Rails`, and so incorrect
indentation for `private` methods is properly detected.
