verify does not throw exception when too many arguments are passed

[mweitzel]

Verify doesn't throw exceptions when too many arguments are passed. Right now its only on too few arguments or collisions.

I expected td.verify(double('any', 'parameters')) to default to checking arity, but currently only fails on too few arguments. Here's an example reproduction:

In a file td-repro.js

var td = require('testdouble')
  , test = require('tape')

test('verify tests arity matches', function(t) {
  t.plan(4)

  var stub0 = td.create()
  var stub1 = td.create()
  var stub2 = td.create()
  var stub3 = td.create()

  t.doesNotThrow(function() {
    stub0('any arguments', 0, 1, 2)
    td.verify(stub0())
  }, 'called with more arguments when none are specified')

  t.throws(function() {
    stub1(0)
    td.verify(stub2(0,0))
  }, 'called with fewer arguments fails')

  t.doesNotThrow(function() {
    stub2(0,0)
    td.verify(stub2(0,0))
  }, 'called with the same number succeeds')

  t.throws(function() {
    stub3(0,0,1)
    td.verify(stub3(0,0))
  }, 'called with more arguments fails') //   <-- does not fail
})

The command node td-repro.js gives this output:

TAP version 13
# verify tests arity matches
ok 1 called with more arguments when none are specified
ok 2 called with fewer arguments fails
ok 3 called with the same number succeeds
not ok 4 called with more arguments fails
