...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...
