FIX: "Transform failure" error when the unit test for Maps is used in a BizTalk Server project

Applies to: BizTalk Server 2013 BranchBizTalk Server 2013 DeveloperBizTalk Server 2013 Enterprise


When you use the Unit Testing feature for Schemas and Maps in a Microsoft BizTalk Server 2013 project, the unit test for Maps does not work. Additionally, you receive the following error message:

Transform failure


This issue occurs because the TestableMapBase class is not upgraded in BizTalk Server 2013. In this case, the BTSXsTransform class is still being used instead of the XslCompiledTransform class.


Cumulative update information

The fix that resolves this issue is included in Cumulative Update 3 for BizTalk Server 2013.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
