module Micronaut
# Micronaut::Expectations lets you set expectations on your objects.
#
# result.should == 37
# team.should have(11).players_on_the_field
#
# == How Expectations work.
#
# Micronaut::Expectations adds two methods to Object:
#
# should(matcher=nil)
# should_not(matcher=nil)
#
# Both methods take an optional Expression Matcher (See Micronaut::Matchers).
#
# When +should+ receives an Expression Matcher, it calls <tt>matches?(self)</tt>. If
# it returns +true+, the spec passes and execution continues. If it returns
# +false+, then the spec fails with the message returned by <tt>matcher.failure_message</tt>.
#
# Similarly, when +should_not+ receives a matcher, it calls <tt>matches?(self)</tt>. If
# it returns +false+, the spec passes and execution continues. If it returns
# +true+, then the spec fails with the message returned by <tt>matcher.negative_failure_message</tt>.
#
# Micronaut ships with a standard set of useful matchers, and writing your own
# matchers is quite simple. See Micronaut::Matchers for details.
