Matahari::InvocationMatcher

Public Class Methods

new(iterator = nil) click to toggle source

TODO I can’t work out how to disentangle the 2 responsibilities of this class:

  1. Inspecting and acting on spy invocations

  2. Presenting the results of those inspections.

One to revisit later when my head is less befuddled.

# File lib/matahari/invocation_matcher.rb, line 10
def initialize(iterator = nil)
  @expected_call_count = iterator ? iterator.count : nil
end

matches?(subject) click to toggle source
# File lib/matahari/invocation_matcher.rb, line 14
def matches?(subject)
  @subject = subject
  @invocations_of_method = subject.invocations.select {|i| i.method == @call_to_verify}
  verifying_args = @args_to_verify.size != 0

  match_passes?(verifying_args)
end
method_missing(sym, *args, &block) click to toggle source

Allows chaining of method calls following has_received?/should have_received, e.g. spy.should_have received.some_method, where some_method is handled by method_missing, its arguments and name being stored until matches? is called.

# File lib/matahari/invocation_matcher.rb, line 37
def method_missing(sym, *args, &block)
  @call_to_verify = sym
  @args_to_verify = args
  self
end
