It is always helpful to build and save known-good Ruletests (.ert files) for the Corticon Rulesheets and Ruleflows you intend to deploy. A Ruletest known to be good not only verifies that Rulesheet or Ruleflow is producing the expected results for a given scenario, it also enables you to re-test and re-verify these results at any time in future.

If you do not have a known-good Ruletest, build one now to verify that the Ruleflow, as it exists right now, is producing the expected results. If you have access to the actual data set or scenario that produced the error in the first place, it is especially helpful to use it here now. Run the Ruletest.
