### Question:
AtlasUtil { public static Properties loadPropertiesFromURL(URL url) throws Exception { try (InputStream is = url.openStream()) { Properties prop = new Properties(); prop.load(is); return prop; } }  static Properties loadPropertiesFromURL(URL url); static boolean isEmpty(String string); static boolean matchUriModule(String uriA, String uriB); static String getUriScheme(String atlasUri); static String getUriModule(String atlasUri); static String getUriDataType(String atlasUri); static String getUriModuleVersion(String atlasUri); static String getUriParameterValue(String atlasUri, String key); static Map<String, String> getUriParameters(String atlasUri); static int countCharacters(String text, char match); static List<Class<?>> findClassesForPackage(String scannedPackage); static void addAudit(AtlasSession session, String docId, String message, String path, AuditStatus status,

@Test public void testLoadPropertiesFromURL() throws Exception { URL url = Paths.get("src" + File.separator + "test" + File.separator + "resources" + File.separator + "AtlasUtilTest.properties").toUri().toURL(); Properties properties = AtlasUtil.loadPropertiesFromURL(url); assertNotNull(properties); assertEquals("value1", properties.get("key1")); assertEquals("value2", properties.get("key2")); }
@Test(expected = NullPointerException.class) public void testLoadPropertiesFromURLNullPointerException() throws Exception { AtlasUtil.loadPropertiesFromURL(null); }
@Test(expected = MalformedURLException.class) public void testLoadPropertiesFromURLMalformedURLException() throws Exception { AtlasUtil.loadPropertiesFromURL(new URL("invalid URL")); }
