Hamcrest matcher for a sublist/partial match?

Question

Say I have an actual List [1, 2, 3, 4] and I want to check if it contains the sub-list [2, 3] (i.e. order is also important). Is there an existing matcher that does this?

(There's a poorly-named hasItems method which only checks the actual list matches any one item in the expected list....)

Answer 1

Write your own if you can.

see Writing custom matchers

It should be something like:

 public class HasSublist<T> extends TypeSafeMatcher<T> {

     @Override
      public boolean matchesSafely(List<T> subList) {
        //Logic if sublist exist ...
        return true;
      }

      public static <T> Matcher<T> hasSubList(List<T> containsSublist) {
        return new HasSublist<T>(containsSublist);
      }
}
