Contributions to ruby/spec · On the Edge of Ruby

Rubinius started ruby/spec (called RubySpec back then) and was the main contributor until 2014. In 2015, Rubinius development slowed down significantly and so did their work on adding specs (more on that in this 10 years old post). In 2014, TruffleRuby was started and quickly became the main contributor to ruby/spec, contributing more than half of all commits since then. CRuby has contributed consistently to ruby/spec, around 20% of all commits each year. This is great to see as CRuby is in the unique position of implementing new methods first and deciding the expected behavior. JRuby contributed significantly until 2012 but since then has made few contributions. Natalie, a Ruby implementation started in 2019 made significant contributions since 2022, big thanks to @herwinw which contributed most of that.
