unit-testing - 你如何对 Jboss Rules (Drools) 规则进行单元测试？

Question

我已经为我的 Seam 应用程序编写了一些 Drools 规则，我想知道我如何对这些进行单元测试。有没有人有任何示例代码可以告诉我如何去做？

Answer 1

将以下代码添加到单元测试(JUnit、TestNG 等)中:

PackageBuilder builder = new PackageBuilder();

builder.addPackageFromDrl(new InputStreamReader(getClass().getResourceAsStream( "rules.drl")));

PackageBuilderErrors errors = builder.getErrors();

Assert.assertEquals(0, errors.getErrors().length);

RuleBase ruleBase  = RuleBaseFactory.newRuleBase();
ruleBase.addPackage(pkg);

StatefullSession session = ruleBase.newStatefulSession(false);

MyFactObject myFact = new MyFactObject();

session.insert(myFact);
session.fireAllRules();
