If we are testing the output of these files, then we have to place the tags in a <cfSaveContent /> tag pair and store the result for retrieval during the test. During the run of the test, we can run the include code or custom tag, and pull the comparison content from the storage source for comparison. That is all there is to it.

When using custom tags, there are times when these tags use the caller scope to set variables external to the tag. Pure object oriented guys will choke to consider this practice.
