emptyIterable
public static <E> org.hamcrest.Matcher<java.lang.Iterable<? extends E>> emptyIterable()
- Creates a matcher for
Iterable
s matching examined iterables that yield no items.

assertThat(new ArrayList<String>(), is(emptyIterableOf(String.class)))
- Parameters:
type
- the type of the iterable's content
