What is RSpec?
RSpec is a testing framework for Ruby implementing Behaviour Driven Development principles, making test-driven development productive and fun through a focus on writing examples that express desired behavior.
What RSpec does

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for RSpec, not the verdict.
