### Question:
CronInvocation implements Runnable { public void addCrontabLine(RawCrontabLine line) { crontabRepos.add(parser.parseLine(line)); }  @Override void run(); void initialize(TaskunInjector taskunInjector, ScheduledExecutorService executorService); void initialize(TaskunInjector taskunInjector, ScheduledExecutorService executorService, String crontabFilepath); void addCrontabLine(RawCrontabLine line); List<RawCrontabLine> getCurrentRawCrontabLines(); long getPreviousCheckedTimeMillis();  }### Answer:
@Test public void addCrontabLine_A$RawCrontabLine() throws Exception { RawCrontabLine line = new RawCrontabLine("*/1 * * * * tmp"); crond.addCrontabLine(line); }
