The future of shoulda
in Ruby added by admin, on 18/6/2010 framework ruby on rails shoulda testing
Shoulda has long been one of our most useful and popular open source projects, and it continues to serve us well as we use it daily. However, there have been some changes over the past year in the way that we use Shoulda, and these changes have led to some decisions about its future. In our post about the Rails 3 roadmap, we briefly covered the changes we made in Shoulda 2.11 as well as our intentions for Shoulda 3. However, we wanted to go over these changes in depth and explain some of our motivation.
