fast-ruby VS RSpec style guide

In this perspective, maybe the compilation of approaches by Fast Ruby provides a similar point of entry.

Great article! I'm one of the maintainers of the `fast-ruby` project and I was glad to see that we have a benchmark for those idioms over here: https://github.com/fastruby/fast-ruby/blob/master/code/general/attr-accessor-vs-getter-and-setter.rb 🤓

Stylistically, chomp has a bit more of the whimsy that you might expect from Ruby, while delete_suffix is a nice mirroring of delete_prefix and more explicitly named. Both have similar performance benchmarks and are faster than sub.

If you’re interested in speed, check this repo: even among Ruby idioms there are big speed differences.

betterspecs.org is a good resource.

Both sites advocate for factories over fixtures (though there is a not clear consensus). With fixtures, test objects are all defined in fixture files with predefined data. Fixtures can be used across tests but modifying an existing fixture can break tests that depend on that fixture. As a codebase grows managing fixtures for all the various states of your object can be difficult. In comparison, factories let you build and configure new objects per test.
