CoreMatchers提供了很多匹配器，对于junit相对单薄的断言功能是很好的补充。

static <T> Matcher<java.lang.Iterable<? super T>>	hasItem(Matcher<? super T> itemMatcher) Creates a matcher for Iterable s that only matches when a single pass over the examined Iterable yields at least one item that is matched by the specified itemMatcher .
static <T> Matcher<java.lang.Iterable<? super T>>	hasItem(T item) Creates a matcher for Iterable s that only matches when a single pass over the examined Iterable yields at least one item that is equal to the specified item .
static <T> Matcher<java.lang.Iterable<T>>	hasItems(Matcher<? super T>... itemMatchers) Creates a matcher for Iterable s that matches when consecutive passes over the examined Iterable yield at least one item that is matched by the corresponding matcher from the specified itemMatchers .
