### Question:
CrontabElement { public boolean isNotWildcard() { return !this.toString().equals("*"); } CrontabElement(String element); @Override String toString(); @Override boolean equals(Object obj); int toInt(); long toLong(); boolean isFixedValue(); boolean isWildcard(); boolean isNotWildcard();  }### Answer:
@Test public void isNotWildcard_A$_false() throws Exception { CrontabElement element = new CrontabElement("*"); boolean actual = element.isNotWildcard(); boolean expected = false; assertEquals(expected, actual); }
@Test public void isNotWildcard_A$String_true() throws Exception { String[] arg = new String[]{"1", "*/3", "1-59/3", "1,2,3"}; for (int i = 0; i < arg.length; i++) { assertTrue(arg[i], new CrontabElement(arg[i]).isNotWildcard()); } }
