initializes a new empty instance of the Expectation collection

Public Instance Methods

add_expectation(expectation, mode=:instance) click to toggle source

Adds an expectation to this collection. From then on it can be found in the collection.

# File lib/caricature/expectation.rb, line 14
    def add_expectation(expectation, mode=:instance)
      @instance_expectations << expectation unless mode == :class
      @class_expectations << expectation if mode == :class
    end

find(method_name, mode=:instance, *args) click to toggle source

Finds an expectation in the collection. It matches by method_name first. Then it tries to figure out if you care about the arguments. You can say you don’t care by providing the symbol :any as first argument to this method. When you don’t care the first match is being returned When you specify arguments other than :any it will try to match the specified arguments in addition to the method name. It will then also return the first result it can find.

# File lib/caricature/expectation.rb, line 24
    def find(method_name, mode=:instance, *args)
      expectations = mode == :class ? @class_expectations : @instance_expectations
      candidates = expectations.select { |exp| exp.method_name.to_s.to_sym == method_name.to_s.to_sym }
      is_single = args.empty? || args.first == :any || (candidates.size == 1 && candidates.first.any_args?)
      return candidates.first if is_single

      second_pass = candidates.select {|exp| exp.args == args }
      second_pass.first
    end
