Just my collection, so you do not need to find it out on your own 😉

• :expire now is called :expires_in, update your cache calls or timed expiring will fail
• get rspec edge/ rspec-rails edge
  detailed instruction
  also possible and easy: sudo gem install dchelimsky-rspec dchelimsky-rspec-railsyou may need to add this when you are on 1.1.99.9 and get
  no such file to load — spec/rails/example/routing_example_group
  from github
• get webrat 0.4.2 (atm only by installing from github clone + rake gem + sudo gem install)
• truncate(‘xxx’,3) ==> truncate(‘xxx’,:length=>3)
• Model.find_by_xxx will now call Model.find with :conditions=>{:xxx=>something}, this broke some of my stubs/mocks, e.g. User.stubs(:find) worked before but now came in conflict with user login that used find_by_id
• render :inline seems not to be testable, all my request.body from render :inline are blank now (rspec 1.1.12)
• stub_model install rspec-rails-mocha — ./script/plugin install git://github.com/mislav/rspec-rails-mocha.git
• count returns OrderedHash, so tests now look like xxx.to_a.should == [[‘name’,2]]
• String.chars does not have the [] method anymore, so e.g. only “xxx”.mb_chars[1..4] will work
• @template will no longer work in vie tests, use response instead
• have_tag returns
  undefined method `id2name’ for {:instance_writer=>false}:Hash
  , upgrade the money gem!
• controller tests are no longer able to call actions that are not defined (e.g. no action was defined because it only renders a view and does nothing or because the action was included from a module)
• HopToad will silently fail, use this branch instead: http://github.com/pzingg/hoptoad_notifier (as long as thoughbot does not update their own of course)
• work systematically e.g. rake spec:models, then rake spec:controllers … or you may get mad 😉
