### Question:
DateList { public static void main(String[] args) throws IOException, ParseException { if (!checkArgsOk(args)) { System.exit(1); } String dateList = createDateListFromArgs(args); System.out.println("datelist :" + dateList+ ":"); writeWorkflowOutput(dateList); }  static void main(String[] args);  }### Answer:
@Test public void testExitStatusIs_1_IfTooFewCLIArgs() throws IOException, ParseException { final String[] too_few_args = {START, END, FREQUENCY, TIMEUNIT}; LauncherSecurityManager securityManager = new LauncherSecurityManager(); securityManager.enable(); try { expectedException.expect(SecurityException.class); DateList.main(too_few_args); } finally { assertTrue(securityManager.getExitInvoked()); assertEquals("Unexpected exit code.", 1, securityManager.getExitCode()); securityManager.disable(); } }
@Test public void testCorrectOutput() throws IOException, ParseException { final String[] args = {START, END, FREQUENCY, TIMEUNIT, TIMEZONE}; final File output_file = folder.newFile("action_output.properties"); final String output_filename = output_file.getCanonicalPath(); System.setProperty("oozie.action.output.properties", output_filename); DateList.main(args); Properties props = new Properties(); try (InputStream is = new FileInputStream(output_file)) { props.load(is); } assertEquals("Incorrect date list.", EXPECTED_DATE_RANGE, props.getProperty("datelist")); }
