Question

I am writing some unit tests for my Ruby on Rails application. I would like to test that my model received a message to a particular method. In RSpec this is done with the should_receive incantation.

Is there an equivalent to Test::Unit that can do the same? If Test::Unit cannot do it, is there a tool I can use in concert with it to get that functionality?

Answer 1

Check out mocha. It is a gem that you can use with Test::Unit or Rspec (but I prefer the native rspeck mocking). It allows you to write something like

@post.stubs(:something).returns(:bla)
@post.expects(:something_else).raises(StandardError, "failed")

Hope this helps
