Testing rule variations
You can use test rules to create variations of a rule and compare output results.
Test rules allow you to create alternatives to rules that are already created. This enables you to make variations to the rule and compare the output. If you find an alternative rule that gives better results, you can convert it to a live rule.
Test rules do not run in production. However, if the offer that you are testing rule variations for has run at least once, you can see the affect that a test rule has using the Preview function. In the Preview function, the name of the test rule is displayed for any recommendation that was affected by the test rule.
