This post follows on from yesterday's post: Creating BizUnit Test Cases for comparing Xml Files

If you are using the XmlValidationStep/XmlValidationStepEx BizUnit steps and using XPath validation, then it can be a pain to write all these XPathValidation statements by hand.

So I wrote a utility to generate the XPath statements for you.
In fact, it generates the entire BizUnit Test Case for validating an Xml file.
Once it has been generated, all you have to do is[...]

BizUnit is a great tool for performing end-to-end testing of BizTalk applications (and can even be used for testing non-BizTalk applications like Web services too).
Although you're not strictly performing unit-testing of your BizTalk artefacts per-se, with the right setup you can get very close to unit testing.

For example if you want to test an orchestration in isolation you can:

1. Hook your orchestration up to file send/receive ports
   or
2. Write a façade orchestration which calls your orchestration, and is itself hooked up to file send/receive ports or
   or
3. Write your own orchestration hosting engine

I don't know many people who'd be crazy enough to do 3) (although I do know one…) but BizUnit is of great help for 1) and 2)

In its simplest form you can use BizUnit to[...]

This is something that bit me recently:
The current version of BizUnit (v.2.2.1003.0)  uses the .NET 1.0 XmlValidatingReader to do schema validation in both the XmlValidationStep and XmlValidationStepEx steps.

.NET 2.0 deprecated the XmlValidatingReader class, proposing that you use the XmlReader class and the new XmlReaderSettings class instead.
Microsoft also introduced a slew of bug fixes to the validation logic[...]
