### Question:
FileSystemManager implements Initializable { @Override public void shutdown() { started.set(false); } protected  FileSystemManager(); static FileSystemManager getInstance(); List<String> getTopLevelDirectories(Set<String> exclude); File getDir(String directory); File getConfig(String configFilename); File getImportLookup(String configFilename); File getImportLookup(String configFilename, NewFileHandler newFileHandler); InputStream getApplicationResourceFile(String resource); long copy(InputStream source, OutputStream sink); @Override void initialize(); @Override void shutdown(); @Override boolean isStarted(); String getBaseDirectory(); void setBaseDirectory(String baseDirectory); static final String MAIN_PERM_DIR; static final String MAIN_TEMP_DIR; static final String SYSTEM_TEMP_DIR; static final String CONFIG_DIR; static final String IMPORT_DIR; static final String IMPORT_HISTORY_DIR; static final String IMPORT_LOOKUP_DIR; static final String IMPORT_ARTICLE_DIR; static final String IMPORT_HIGHLIGHT_DIR; static final String IMPORT_COMPONENT_DIR; static final String ARTICLE_DIR; static final String MEDIA_DIR; static final String ATTACHMENT_DIR; static final String ARCHIVE_DIR; static final String GENERAL_MEDIA_DIR; static final String SUPPORT_MEDIA_DIR; static final String TEMPORARY_MEDIA_DIR; static final String ERROR_TICKET_DIR; static final String RESOURCE_DIR; static final String ORGANIZATION_DIR; static final String REPORT_DIR; static final String PLUGIN_DIR; static final String COMPONENT_VERSION_DIR; static final String PLUGIN_UNINSTALLED_DIR; static final String PLUGIN_FAILED_DIR; static final String DB_DIR; }### Answer:
@Test public void testShutdown() { LOG.info("shutdown"); testFileSystemManager.shutdown(); if (testFileSystemManager.isStarted()) { fail("File manager should NOT be started"); } }
