Write your thoughts about the "create only the data you need" best practice.
@andreareginato It seems that have / have_at_least / have_at_most were deprecated.
rspec-expectations 2.99.0.beta1 - Full Changelog
Deprecations: Deprecate have, have_at_least and have_at_most.
You can continue using those matchers through https://github.com/rspec/rspec-collection_matchers,
or you can rewrite your expectations with something like expect(your_object.size).to eq(num).
would suggest updating those examples...
@eladg Feel free to submit a pull request with changes. It would be much appreciated.
