Test Driven SOA - citrus for powerful SOA test coverage

Reading parts of Test-Driven Development for Embedded C" by James W. Grenning inspired me to take another look at this area and look for something new,  fresh and powerful for use in the SOA world. 

I don't think we need much convincing on the importance of  automated test coverage (if someone does, please read the first chapter of the book mentioned above, especially the section on "Physics of TDD" that tries to quantify the high long-term costs of "Debug later programming" - the nemesis of TDD)

A very simple application with a SOA composite project and Tests project can be found here:

Although the test in this is just a simple SOAP request, what I am interested in are the features that citrus has to offer that can help create a solid battery of tests. 

  • Tests can be specified in Java or XML or a combination of both
  • A number of test utilities are inbuilt - including things like database access, JMS,mock SOAP endpoints (static responses), complex assertions - and these can be used to write complex setup and teardown routines

I will leave the reader to peruse the code on github but this shows the most important pieces of config in my test project:

  • To build+deploy+test, after making sure your SOA server is running, just run "mvn integration-test" from the application level (provide serverUrl, user and password in the SOAComposite pom or from the environment e.g. -serverUrl=http://soahost:port)
  • To only run the integration tests, just run "mvn integration-test" from the SOAApplication/SOACompositeTests level.

This is all neat and CI ready!
