I cannot find any class allowing me to write my tests like:

String actual = tested.buildUrlWithRandomPort("foo", "bar");
assertThat(actual, matchesRegex("^foo://bar:\\d+/$");
// fails with a message like:
// expected <foo://bar:/> to match a regular expression <^foo://bar:\d+/$>

I think that Hamcrest Library should offer matchesReges() together with containsString(), endsWith() and startsWith().

Is there a matcher like this available in the master branch? If not, I could write one (something similar to Hamcrest Regex Matcher) and create a pull request.
