    Rule Unit Testing is the process of testing a specific rule in the context of the rule set in which it is deployed.&#xD;
    Rule Unit Testing allows rule writers to:&#xD;

    &lt;span style=&quot;mso-bidi-language: HE&quot;>There is a major difference between testing a code, and a rule. A rule engine per&#xD;
    design may not put a rule in the agenda if the conditions are not matched. This means that when the rule writer write a&#xD;
    new rule, even if the data are sent to trigger the execution of this new rule it is possible that a rule fired before&#xD;
    the new one, with change the condition of the data so that this new rule will never be eligible. Developing a complete&#xD;
    set of unit test is an efficient way to see this problem, and to improve the rule set design. Some powerful BRMS&#xD;
    platform has rules consistency checking which helps to do some static analysis of those potential conflict by analyzing&#xD;
    the conditions and the actions of the rules. For sure real test cases will complete the picture.&lt;/span>&#xD;

a Test Driven Development approach rule writer can develop the test script preparing the data to trigger each rule,&#xD;
depending of the BRMS platform used, the script generation can be done automatically or not. What is important is develop&#xD;
reusable test case organized in test suite which include assertion statement to validate the expected results. This is&#xD;
efficient tool to put in place automatic non regression tests.&lt;/span></mainDescription>
