### Question:
Functions { public static boolean matches(String value, String pattern) { try { return Pattern.compile(pattern).matcher(value).find(); } catch (PatternSyntaxException pse) { } return false; } private  Functions(); static String[] array(String... values); static boolean contains(Object object, Object value); static int indexOf(String value, String substring); static String join(String[] values, String separator); static String keyMatch(Object map, String pattern); static int length(Object value); static boolean matches(String value, String pattern); static String[] matchingGroups(String value, String pattern); static String[] split(String value, String regex); static String toLowerCase(String value); static String toString(Object value); static String toUpperCase(String value); static String trim(String value); static String urlEncode(String value); static String urlDecode(String value); static String encodeBase64(final String value); static String decodeBase64(final String value); static String read(final String filename); static Properties readProperties(final String filename);  }### Answer:
@Test(dataProvider = "matchData") public void matches(String s, String pattern, boolean matches, String[] groups) throws Exception { attributes.put("s", s); Boolean o = Expression.valueOf("${matches(attributes.s, '" + pattern + "')}", Boolean.class) .eval(bindings); assertThat(o).isEqualTo(matches); }
