@Test public void testFindLanguageNames() throws Exception { List<String> names = catalog.findLanguageNames(); assertNotNull(names); assertFalse(names.isEmpty()); assertTrue(names.contains("constant")); assertTrue(names.contains("simple")); assertTrue(names.contains("bean")); assertFalse(names.contains("spel")); }
