How to use mock method of RR.DSL Package

Best Rr_ruby code snippet using RR.DSL.mock

wildcard_matchers.rb

Source:wildcard_matchers.rb

...5As an example, let's say that you want a matcher that will match any number6divisible by a certain integer.  In use, it might look like this:7  # Will pass if BananaGrabber#bunch_bananas is called with an integer8  # divisible by 5.9  mock(BananaGrabber).bunch_bananas(divisible_by(5))10To implement this, we need a class RR::WildcardMatchers::DivisibleBy with11these instance methods:12* ==(other)13* eql?(other) (usually aliased to #==)14* inspect15* wildcard_match?(other)16and optionally, a sensible initialize method.  Let's look at each of these.17=== .initialize18Most custom wildcard matchers will want to define initialize to store19some information about just what should be matched.  DivisibleBy#initialize20might look like this:21  class RR::WildcardMatchers::DivisibleBy22    def initialize(divisor)23      @expected_divisor = divisor24    end25  end26=== #==(other)27DivisibleBy#==(other) should return true if other is a wildcard matcher that28matches the same things as self, so a natural way to write DivisibleBy#== is:29  class RR::WildcardMatchers::DivisibleBy30    def ==(other)31      # Ensure that other is actually a DivisibleBy32      return false unless other.is_a?(self.class)33      # Does other expect to match the same divisor we do?34      self.expected_divisor = other.expected_divisor35    end36  end37Note that this implementation of #== assumes that we've also declared38  attr_reader :expected_divisor39=== #inspect40Technically we don't have to declare DivisibleBy#inspect, since inspect is41defined for every object already.  But putting a helpful message in inspect42will make test failures much clearer, and it only takes about two seconds to43write it, so let's be nice and do so:44  class RR::WildcardMatchers::DivisibleBy45    def inspect46      "integer divisible by #{expected.divisor}"47    end48  end49Now if we run the example from above:50  mock(BananaGrabber).bunch_bananas(divisible_by(5))51and it fails, we get a helpful message saying52  bunch_bananas(integer divisible by 5)53  Called 0 times.54  Expected 1 times.55=== #wildcard_matches?(other)56wildcard_matches? is the method that actually checks the argument against the57expectation.  It should return true if other is considered to match,58false otherwise.  In the case of DivisibleBy, wildcard_matches? reads:59  class RR::WildcardMatchers::DivisibleBy60    def wildcard_matches?(other)61      # If other isn't a number, how can it be divisible by anything?62      return false unless other.is_a?(Numeric)63      # If other is in fact divisible by expected_divisor, then64      # other modulo expected_divisor should be 0.65      other % expected_divisor == 066    end67  end68=== A finishing touch: wrapping it neatly69We could stop here if we were willing to resign ourselves to using70DivisibleBy this way:71  mock(BananaGrabber).bunch_bananas(DivisibleBy.new(5))72But that's less expressive than the original:73  mock(BananaGrabber).bunch_bananas(divisible_by(5))74To be able to use the convenient divisible_by matcher rather than the uglier75DivisibleBy.new version, re-open the module RR::DSL and define divisible_by76there as a simple wrapper around DivisibleBy.new:77  module RR::DSL78    def divisible_by(expected_divisor)79      RR::WildcardMatchers::DivisibleBy.new(expected_divisor)80    end81  end82== Recap83Here's all the code for DivisibleBy in one place for easy reference:84  class RR::WildcardMatchers::DivisibleBy85    def initialize(divisor)86      @expected_divisor = divisor87    end...
