### Question:
UnitRuleGroup extends CompositeRule { @Override public boolean evaluate(Facts facts) { if (!rules.isEmpty()) { for (Rule rule : rules) { if (!rule.evaluate(facts)) { return false; } } return true; } return false; } UnitRuleGroup();  UnitRuleGroup(String name);  UnitRuleGroup(String name, String description);  UnitRuleGroup(String name, String description, int priority); @Override boolean evaluate(Facts facts); @Override void execute(Facts facts);  }### Answer:
@Test public void whenNoComposingRulesAreRegistered_thenUnitRuleGroupShouldEvaluateToFalse() { unitRuleGroup = new UnitRuleGroup(); boolean evaluationResult = unitRuleGroup.evaluate(facts); assertThat(evaluationResult).isFalse(); }
