BizTalk Documenter, BizTalk Orchestration Profiler & BizUnit

Three tools every BizTalk-developer should be aware of, are BizTalk Documenter, BizTalk Orchestration Profiler and BizUnit. The documentation below is copied from the homepages of these tools.

BizTalk Documenter
Creates compiled help files for a given BTS 2006 installation. This tool can be run on an ad-hoc basis using the UI or from the command line as a post build/deploy task to create a compiled help file describing a BTS 2006 installation. It will compile: BTS Host configuration, Send/Receive port configuration, Orchestration diagrams, Schema and Map content, Pipeline process flow, Adapter configuration, Rule engine vocabularies and policies, … and publish them as compiled help files. Optionally you can embed custom HTML content and custom descriptions for all BTS artifacts to produce a more customized look and feel to the CHM output.

BizTalk Orchestration Profiler
Creates CHM report files illustrating the level of coverage for specified BizTalk orchestrations. This tool can be run to gain a consolidated view of orchestration tracking data for a specified period of time to help developers get an idea of how their orchestrations are being processed and how much coverage they are getting in their testing. In addition to simple coverage information the data presented helps to identify latency and code path exceptions by highlighting long running and error prone orchestration shapes which is key to effective performance testing.

BizUnit
BizUnit enables automated tests to be rapidly developed. BizUnit is a flexible and extensible declarative test framework targeted that rapidly enables the automated testing of distributed systems, for example it is widely used to test BizTalk solutions. BizUnit is fully extensible. Its approach is to enable test cases to be constructed from generic reusable test steps, test cases are defined in XML which allows them to be auto-generated and also enables the fixing up of URL’s for different environments, e.g. test, staging and production environments. Defining test cases in XML enables test cases to be auto-generated.
