Re: [rules-users] Drools 6 Junit Random Failures

Looks close enough to what I tend to do. It could be worth firing off something like the following to double-check that your knowledge base and working memory are as expected prior to each test. /** * Iterates through the facts currently in working memory, and logs their details. * * @param session The session to search for facts. */ public static void printFacts(KieSession session) { StringBuilder sb = new StringBuilder(); sb.append("\n************************************************************"); sb.append("\nThe following facts are currently in the system..."); for (Object fact : session.getObjects()) { sb.append("\n\nFact: “ + fact.toString()); } sb.append("\n************************************************************\n"); log.info(sb.toString()); } /** * * @return A String detailing the packages and rules in this knowledge base. */ public static String kbaseDetails(KieBase kbase) { StringBuilder sb = new StringBuilder(); for (KiePackage p : kbase.getKiePackages()) { sb.append("\n Package : " + p.getName()); for (Rule r : p.getRules()) { sb.append("\n Rule: " + r.getName()); } } return "Knowledge base built with packages: " + sb.toString(); } On 29 Apr 2014, at 09:47, richardhands <richard.hands(a)uk.sopragroup.com&gt; wrote:
