Assert regex matches in JUnit

Question

Ruby\'s Test::Unit has a nice assert_matches method that can be used in unit tests to assert that a regex matches a string.

Is there anythi

Answer 1

Because I was also looking for this functionality, I have started a project on GitHub called regex-tester. It's a library that helps ease testing regular expressions in Java (only works with JUnit currently).

The library is very limited right now, but it does have a Hamcrest matcher that works like this

assertThat("test", doesMatchRegex("tes.+"));
assertThat("test", doesNotMatchRegex("tex.+"));

More about how to use regex-tester is here.
