RubySpec

The RubySpec project aimed to write a complete executable specification for the Ruby programming language. This project contains specs that describe Ruby language syntax and standard library classes. The project contains two main components:

  • the RubySpec sources
  • the MSpec framework

The RubySpec test suite captured most of 1.8.6/1.8.7/1.9 behavior as a reference conformance tool. Ruby MRI 1.9.2 passed over 99% of RubySpec., while version 2.2.0 crashed on one of the tests.
