### Question:
Patterns { public static Pattern newHelperIntegerLiteralPattern() { return Pattern.compile("(\\+|-)?\\d{1,10}"); } private  Patterns(); static Pattern newMustacheTagPattern(Configuration configuration); static Pattern newSetDelimitersContentPattern(); static Pattern newHelperIntegerLiteralPattern(); static Pattern newHelperLongLiteralPattern();  }### Answer:
@Test public void testHelperIntOrLongLiteralPattern() { assertFalse(Patterns.newHelperIntegerLiteralPattern() .matcher("\"foo\"").matches()); assertTrue(Patterns.newHelperIntegerLiteralPattern().matcher("1") .matches()); assertTrue(Patterns.newHelperIntegerLiteralPattern().matcher("+12") .matches()); assertTrue(Patterns.newHelperIntegerLiteralPattern().matcher("-10000") .matches()); assertFalse(Patterns.newHelperIntegerLiteralPattern().matcher("1.0") .matches()); assertFalse(Patterns.newHelperIntegerLiteralPattern() .matcher("1000000000000").matches()); }
