### Test d'integration

Lancer le serveur Fess et éxécuter la commande suivante :

    $ mvn test -P integrationTests -Dtest.fess.url="http://localhost:8080" -Dtest.search_engine.url="http://localhost:9201"

Pour exécuter un seul cas de test case, vous pouvez utiliser la commande suivante :

        final String id = form.id;
        crawlingInfoService.getCrawlingInfo(id).ifPresent(entity -> {
            try {
                processHelper.sendCommand(entity.getSessionId(), Constants.CRAWLER_PROCESS_COMMAND_THREAD_DUMP);
                saveInfo(messages -> messages.addSuccessPrintThreadDump(GLOBAL));
            } catch (final Exception e) {
                logger.warn("Failed to print a thread dump.", e);

        final String commandTimeoutStr = fessConfig.getSystemProperty("thumbnail.command.timeout");
        if (commandTimeoutStr != null) {
            commandTimeout = Long.valueOf(commandTimeoutStr);
        }
        final String commandDestroyTimeoutStr = fessConfig.getSystemProperty("thumbnail.command.destroy.timeout");
        if (commandDestroyTimeoutStr != null) {

    public static final String SYSTEM_USER = "system";

    public static final String FESS_THUMBNAIL_PATH = "fess.thumbnail.path";

    public static final String FESS_VAR_PATH = "fess.var.path";
