### Question:
DailyLogListener extends RotateLogListener { protected void compress(File logFile) { if (getCompressionFormat() != NONE){ Thread t = getCompressorThread(logFile); try{ if (t != null) t.start(); } catch (Exception e){ logDebugEx("error compressing file",e); } } } DailyLogListener(); void setConfiguration(Configuration cfg); void deleteOldLogs(); String getSuffix(); void setSuffix(String suffix); String getPrefix(); void setPrefix(String prefix); int getRotateCount(); void setRotateCount(int rotateCount); DateFormat getDateFmt(); void setDateFmt(DateFormat dateFmt); String getLastDate(); void setLastDate(String lastDate); String getCompressedSuffix(); void setCompressedSuffix(String compressedSuffix); long getMaxAge(); void setMaxAge(long maxAge); String getDeleteRegex(); void setDeleteRegex(String deleteRegex); int getCompressionFormat(); void setCompressionFormat(int compressionFormat); int getCompressionBufferSize(); void setCompressionBufferSize(int compressionBufferSize);  }### Answer:
@Test public void testCompress() throws Throwable { DailyLogListener dailyLogListener = new DailyLogListener(); dailyLogListener.compress(new File("testDailyLogListenerParam1")); assertEquals(0, dailyLogListener.getCompressionFormat(), "dailyLogListener.getCompressionFormat()"); }
