I have a set of Drools rules that work correctly if I add one fact to the drools engine, if I add two facts, the rules are only applied on the first fact. How can I make the ruleset work for multiple facts?
My traitable fact:
@Traitable
public class Policy {
private String postalCode;
private String houseHold;
private BigDecimal grossPremium;
public Policy(String postalCode, String houseHold) {
this.postalCode = postalCode;
this.houseHold = houseHold;
}
}
My rule set:
import java.math.BigDecimal;
declare trait PolicyWithFactors
policy : Policy
postalCodeFactor : Double
houseHoldFactor : Double
end
rule rule1
when
$f : PolicyWithFactors(policy.postalCode == "1000", postalCodeFactor == null)
then
System.out.println("Running rule1 for " + $f.getPolicy().getHouseHold() + " and " + $f.getPolicy().getPostalCode());
modify($f) { setPostalCodeFactor(20.0); }
end
rule rule2
when
$p : Policy()
not PolicyWithFactors()
then
System.out.println("Running rule2 for " + $p.getHouseHold() + " and " + $p.getPostalCode());
PolicyWithFactors $pwf = don($p, PolicyWithFactors.class);
modify ($pwf) { setPolicy($p); }
end
rule rule3
when
$p : Policy(houseHold == "single")
$f : PolicyWithFactors(houseHoldFactor == null)
then
System.out.println("Running rule3 for " + $p.getHouseHold() + " and " + $p.getPostalCode());
modify($f) { setHouseHoldFactor(10.0); }
end
rule rule4
when
$p : Policy(grossPremium == null)
$f : PolicyWithFactors(policy == $p, $pcf : postalCodeFactor != null, $hhf : houseHoldFactor != null)
then
System.out.println("Running rule4 for " + $pcf + " and " + $hhf);
BigDecimal $gp = new BigDecimal($pcf * $hhf);
modify($p) { setGrossPremium($gp); }
end
rule rule5
when
$p : Policy(houseHold == "family")
$f : PolicyWithFactors(houseHoldFactor == null)
then
System.out.println("Running rule5 for " + $p.getHouseHold() + " and " + $p.getPostalCode());
modify($f) { setHouseHoldFactor(15.0); }
end
The testcase that is failing:
public class RuleTest {
@Test
public void test() {
KieServices kieServices = KieServices.Factory.get();
KieContainer kieContainer = kieServices.getKieClasspathContainer();
KieSession kieSession = kieContainer.newKieSession();
Policy policy1 = new Policy("1000", "single");
kieSession.insert(policy1);
Policy policy2 = new Policy("1000", "family");
kieSession.insert(policy2);
kieSession.fireAllRules(50);
assertThat(policy1.getGrossPremium(), is(new BigDecimal("200")));
assertThat(policy2.getGrossPremium(), is(new BigDecimal("300")));
}
}
