BizTalk Map test framework

For testing BizTalk solutions the combination of BizUnit and the orchestration profiler are the way to go. Setting it up for a new project can be a hassle, although i appreciate it’s flexibility with the easy of adding custom BizUnit steps.

I just came across a new framework that provides some usefull means of testing BizTalk artefacts, namely maps.

As you might have noticed the support for testing in BizTalk 2009 / BizTalk 2010 is somewhat limited and it forces you to build your artefacts with additional code for mere testing only (the check ‘Enable Unit Test’ will generate a wrapper around the components such as the TestableMapBase in the example below)….the most you will get out of the standard map testing is a validate instance of your message:

Microsoft.BizTalk.TestTools.Mapper.TestableMapBase mapTest = new MapTest.Input2Output();

mapTest.TestMap(
    @"Input.xml",   Microsoft.BizTalk.TestTools.Schema.InputInstanceType.Xml,
     "Output.xml",  Microsoft.BizTalk.TestTools.Schema.OutputInstanceType.XML);

This can be overcome by using a mapping helper component (e.g .from Michael Stephenson) that does a Binary or Xml validation of the result, nevertheless you don’t want to write this on your own.

MapTestingHelper.ValidateMapOutput("Output.xml", “Output.xml");

I’ve tried out the BizTalk map test framework and it allows you to write your testcases using Xpath on fields that you dynamically want to fill with dummy values and predicted outcomes.

Let’s say you want to test a value mapping that returns different results based on the input you can simply write a method that does this validation in just a few lines:

MapTestCases collection = new MapTestCases(
"/*[local-name()='Input']/*[local-name()='InputValue']",
"/*[local-name()='Output']/*[local-name()='ValueOut']"               );

            collection.AddTestCase(
                new string[] { "TEST" }, new string[] { "TRUE" }
                );

            collection.AddTestCase(
                new string[] { "AAH" }, new string[] { "FAL3SE" }
                );
            base.ExecuteMapTest(collection);
            return;

 

I think i like it….check it out here: BizTalk map test framework

Azure implementation guidelines

In My post ‘ Service Bus Management ’ I pointed out a way of implementing a DTAP strategy for managing the Service Bus environment. There’s now a great post available from Microsoft which goes into more detail about other aspects of managing the Azure subscriptions and other artefacts which is quite useful when setting up your Azure environments.

Focus and innovation - recap of the last 2 years

It's been a long time since my last post. Hereby a partial explanation for that, with the note that this blog will remain active for the purpose of being a resource for historical references. My IT career started with programming, and adventures within holland, as well as overseas. When I realised programming is something you can specify, I figured that providing added value is crucial for a long term career and decided to focus on process centric roles. I started with webservice integration and eventually from that to process integration using BizTalk. The great feeling when discussing high level processes and implementing solutions within days, even highly scalable and interfacing with LOB systems is great. After several years of implementing solutions like these, I started questioning if all of this work was justified by the business case, if the solution was actually contributing, if the choices had been valid. In other words, I needed to understand the choices made. When...

BizTalk Pub/sub vs Topics based routing–discussion

My colleagues and I had a brief discussion about the subject ‘Topics’ and what it brings… Do you all agree/disagree with the following statement: topic-based pub-sub messaging doesn’t really exist in BizTalk “In my opinion; I disagree, as BizTalk offers the following 'out-of-the-box' • Message Routing (f.e build in context properties like message type, trading partner, operation etc) • Content Routing (f.e. promoted properties, message inspection in orchestrations/pipelines icw orchestration logic)” My colleague Rene Brauwers Here my 2 cents…. I agree that it exists...however the current offerings in BizTalk are tightly coupled, making the usage far from perfect. When doing content based routing on custom fields (promoted properties), you will be making the solution message-coupled; Your custom message property schema is deployed, and the message filter on these fields have a direct relationship with this property schema. Making any change to this schema will g...
