### Question:
LoadParams { void commit() { Properties prop = new Properties(); try { config.incSuppress(); if (filename != null) { Reader reader = null; try { reader = new InputStreamReader(filename.openStream()); prop.load(reader); } finally { if (reader != null) { reader.close(); } } } prop.putAll(getAllEnv()); applyProperties(new VariablesProperties(prop)); } catch (IOException e) { config.logger.config(FileTools.homeFile(filename.toExternalForm()) + " not found. Use default values."); } finally { config.decSuppress(); } } LoadParams(ReactiveAudit config, String propertiesFile); static String convLevelString(Level level); static final String DEFAULT_THREAD_PATTERN; static final String KEY_AUDIT_FILENAME; static final String KEY_THROW_EXCEPTIONS; static final String KEY_THREAD_PATTERN; static final String KEY_BOOTSTRAP_MODE; static final String KEY_BOOTSTRAP_CPUDELAY; static final String KEY_BOOTSTRAP_DELAY; static final String KEY_FILE_LATENCY; static final String KEY_NETWORK_LATENCY; static final String KEY_CPU_LATENCY; static final String KEY_LOG_OUTPUT; static final String KEY_LOG_FORMAT; static final String DEFAULT_FILENAME; static final Level DEFAULT_LOG_LEVEL; static final String DEFAULT_LOG_OUTPUT; static final String DEFAULT_LOG_FORMAT; static final String DEFAULT_LOG_SIZE; static final String DEFAULT_BOOTSTRAP_CPUDELAY; }### Answer:
@Test public void loadNoFile() { new LoadParams(config, "").commit(); }
