Class MemorisingIterable<T>

  • Type Parameters:
    T - type of elements returned by this iterable
    All Implemented Interfaces:
    Iterable<T>
    public class MemorisingIterable<T>
extends Object
implements Iterable<T>
    Iterable which memorises all generated iterators so that test assertions can be performed. This iterable type generates MemorisingIterable.MemorisingIterator instances, so further data traversal analysis is possible.

    Example usage: 

    
 public void testMyFunction() {
     // provided
     final MemorisingIterable<Integer> data = new MemorisingIterable<>(Arrays.asList(1, 2, 3, 4, 5));

     // when
     callMyFunction(data);

     // then
     assertThat(data.getGeneratedIterators(), hasSize(1));
     assertThat(data.getGeneratedIterators().get(0).getTraversedElements(), contains(1, 2, 3));
 }
