MockFor and StubFor improvements

• Patch Submitted:

  Yes

MockFor and StubFor provide powerful features for mocking but it would be good to have some additional convenience methods and enhancements.

• Proposed number of times feature:

  mock.demand.hasNext(3) { true }

  as shorthand for:

  mock.demand.hasNext(3..3) { true }

• Proposed ignore feature supports code fragments like:

  def mock = new MockFor(AlphaIterator)
  def expectedCount = 2
  mock.ignore('next'){ /* ignored */ }
  mock.demand.hasNext(expectedCount){ true }
  mock.demand.hasNext{ false }
  mock.use {
     assert new IteratorCounter().count(new AlphaIterator()) == expectedCount
  }
