Class MemorisingIterable<T>

java.lang.Object
com.atlassian.bamboo.utils.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));
 }
