### Question:
SyslogMessage extends BaseStep implements StepInterface { public void dispose( StepMetaInterface smi, StepDataInterface sdi ) { meta = (SyslogMessageMeta) smi; data = (SyslogMessageData) sdi; if ( data.syslog != null ) { data.syslog.shutdown(); } super.dispose( smi, sdi ); } SyslogMessage( StepMeta stepMeta, StepDataInterface stepDataInterface, int copyNr, TransMeta transMeta,
      Trans trans ); boolean processRow( StepMetaInterface smi, StepDataInterface sdi ); boolean init( StepMetaInterface smi, StepDataInterface sdi ); void dispose( StepMetaInterface smi, StepDataInterface sdi );  }### Answer:
@Test public void testDispose() throws Exception { SyslogMessageData data = new SyslogMessageData(); SyslogIF syslog = mock( SyslogIF.class ); SyslogConfigIF syslogConfigIF = mock( SyslogConfigIF.class, RETURNS_MOCKS ); when( syslog.getConfig() ).thenReturn( syslogConfigIF ); final Boolean[] initialized = new Boolean[] { Boolean.FALSE }; doAnswer( new Answer<Object>() { public Object answer( InvocationOnMock invocation ) { initialized[0] = true; return initialized; } } ).when( syslog ).initialize( anyString(), (SyslogConfigIF) anyObject() ); doAnswer( new Answer<Object>() { public Object answer( InvocationOnMock invocation ) { if ( !initialized[0] ) { throw new NullPointerException( "this.socket is null" ); } else { initialized[0] = false; } return initialized; } } ).when( syslog ).shutdown(); SyslogMessageMeta meta = new SyslogMessageMeta(); SyslogMessage syslogMessage = new SyslogMessage( stepMockHelper.stepMeta, stepMockHelper.stepDataInterface, 0, stepMockHelper.transMeta, stepMockHelper.trans ); SyslogMessage sysLogMessageSpy = spy( syslogMessage ); when( sysLogMessageSpy.getSyslog() ).thenReturn( syslog ); meta.setServerName( "1" ); meta.setMessageFieldName( "1" ); sysLogMessageSpy.init( meta, data ); sysLogMessageSpy.dispose( meta, data ); }
