### Question:
ViewExtractor { public boolean ensureExtractedArchiveDirectory(String extractedArchivesPath) { File extractedArchiveDir = archiveUtility.getFile(extractedArchivesPath); return extractedArchiveDir.exists() || extractedArchiveDir.mkdir(); }  ClassLoader extractViewArchive(ViewEntity view, File viewArchive, File archiveDir, List<File> viewsAdditionalClasspath); boolean ensureExtractedArchiveDirectory(String extractedArchivesPath);  }### Answer:
@Test public void testEnsureExtractedArchiveDirectory() throws Exception { ResourceTypeEntity resourceTypeEntity = new ResourceTypeEntity(); resourceTypeEntity.setId(10); resourceTypeEntity.setName("MY_VIEW{1.0.0}"); ViewEntity viewDefinition = ViewEntityTest.getViewEntity(); viewDefinition.setResourceType(resourceTypeEntity); expect(extractedArchiveDir.exists()).andReturn(true); replay(extractedArchiveDir, viewArchive, archiveDir, entryFile, classesDir, libDir, metaInfDir, viewJarFile, jarEntry, fos, configuration, viewDir, fileEntry, viewDAO); ViewExtractor viewExtractor = getViewExtractor(viewDefinition); if (System.getProperty("os.name").contains("Windows")) { Assert.assertTrue(viewExtractor.ensureExtractedArchiveDirectory("\\var\\lib\\ambari-server\\resources\\views\\work")); } else { Assert.assertTrue(viewExtractor.ensureExtractedArchiveDirectory("/var/lib/ambari-server/resources/views/work")); } verify(extractedArchiveDir, viewArchive, archiveDir, entryFile, classesDir, libDir, metaInfDir, viewJarFile, jarEntry, fos, configuration, viewDir, fileEntry, viewDAO); reset(extractedArchiveDir); expect(extractedArchiveDir.exists()).andReturn(false); expect(extractedArchiveDir.mkdir()).andReturn(true); replay(extractedArchiveDir); viewExtractor = getViewExtractor(viewDefinition); if (System.getProperty("os.name").contains("Windows")) { Assert.assertTrue(viewExtractor.ensureExtractedArchiveDirectory("\\var\\lib\\ambari-server\\resources\\views\\work")); } else { Assert.assertTrue(viewExtractor.ensureExtractedArchiveDirectory("/var/lib/ambari-server/resources/views/work")); } verify(extractedArchiveDir); reset(extractedArchiveDir); expect(extractedArchiveDir.exists()).andReturn(false); expect(extractedArchiveDir.mkdir()).andReturn(false); replay(extractedArchiveDir); viewExtractor = getViewExtractor(viewDefinition); if (System.getProperty("os.name").contains("Windows")) { Assert.assertFalse(viewExtractor.ensureExtractedArchiveDirectory("\\var\\lib\\ambari-server\\resources\\views\\work")); } else { Assert.assertFalse(viewExtractor.ensureExtractedArchiveDirectory("/var/lib/ambari-server/resources/views/work")); } verify(extractedArchiveDir); }
