An automated method for testing XML/Database/XML layers. To the extent that XML is the de facto communication standard for today's middleware products, most of the middleware products need to produce/accept XML data at some interfaces. This data either comes from or needs to be persisted into DB (database). Two end points are thus represented by XML input/output and DB. To ensure the accuracy of data at the two end points, the same data are typically converted from one format to another between the end points. Manual verification in this vein is possible for development purposes, but in practice this presents inefficiencies if done repeatedly. Accordingly, there is broadly contemplated herein an automation technique to verify the accuracy of data at the two end points.
