### Question:
PSLModel extends Model { public StandardPredicate addPredicate(String name, ConstantType... args) { StandardPredicate predicate = StandardPredicate.get(name, args); dataStore.registerPredicate(predicate); return predicate; } PSLModel(DataStore dataStore); StandardPredicate addPredicate(String name, ConstantType... args); FunctionalPredicate addFunction(String name, ExternalFunction function); Rule addRule(String ruleString); Rule addWeightedRule(String ruleString, double weight, boolean squared); Rule addUnweightedRule(String ruleString); Rule addRule(String ruleString, boolean weighted, double weight, boolean squared); List<Rule> addRules(String rules); List<Rule> addRules(Reader rules); Predicate getPredicate(String name); StandardPredicate getStandardPredicate(String name); FunctionalPredicate getFunctionalPredicate(String name);  }### Answer:
@Test public void testBaseAddPredicate() { model.addPredicate("TestSingleA", ConstantType.UniqueStringID); model.addPredicate("TestSimA", ConstantType.UniqueStringID, ConstantType.UniqueStringID); model.addPredicate("TestSingleB", new ConstantType[]{ConstantType.UniqueStringID}); model.addPredicate("TestSimB", new ConstantType[]{ConstantType.UniqueStringID, ConstantType.UniqueStringID}); }
