/**
 * Note:
 * 		When the build fails while running this test or setting up the applicationContext
 * 		the repository-test artifact could not been found or the ord-context.xml 
 * 		of the repository-test artifact is not onto the classpath. <br>
 * 		So monitoringJobRepository and monitoringStatisticRepository were not initialized and cannot be autowired. <br>
 * 		Furthermore the initialization of the applicationContext of the monitoringModule / -Worker will fail as expected.
 * 
 * Hint: Spying the applicationContext might be helpful. <br>
 * 		 Implement ApplicationContextAware and ignore all test methods. <br> 
 * 		 Then look for just initialized repository beans. <br>
 * 		 Best practise: Map<?,?> aC = applicationContext.getBeansWithAnnotation(Repository.class)
