### Question:
Patterns { public static Pattern newSetDelimitersContentPattern() { return Pattern.compile("(\\S+)(\\s+)(\\S+)"); } private  Patterns(); static Pattern newMustacheTagPattern(Configuration configuration); static Pattern newSetDelimitersContentPattern(); static Pattern newHelperIntegerLiteralPattern(); static Pattern newHelperLongLiteralPattern();  }### Answer:
@Test public void testSetDelimitersPattern() { String set1 = "<% %>"; String set2 = "[ ]"; String set3 = "= ="; Pattern setDelimitersPattern = Patterns .newSetDelimitersContentPattern(); Matcher set1Matcher = setDelimitersPattern.matcher(set1); assertEquals(true, set1Matcher.find()); assertEquals("<%", set1Matcher.group(1)); assertEquals("%>", set1Matcher.group(3)); Matcher set2Matcher = setDelimitersPattern.matcher(set2); assertEquals(true, set2Matcher.find()); assertEquals("[", set2Matcher.group(1)); assertEquals("]", set2Matcher.group(3)); Matcher set3Matcher = setDelimitersPattern.matcher(set3); assertEquals(true, set3Matcher.find()); assertEquals("=", set3Matcher.group(1)); assertEquals("=", set3Matcher.group(3)); }
