SOAPUi and testing WCF Services – how I made it work

· March 3, 2010

I have already blogged about SOAPUi but then it was more me thinking and seeing it was a good idea to use SOAPUi to do testing of service.

Now I have actually done this – and I love it so far. In the last project where we our deliverable was a service I think we spent about 30% of our time creating and maintaining the test client.

Not to speak about all the time we had to spend explaining for the client that “no this is NOT the GUI you will see later on”.

So the thought of a general test client for SOAP services is very compelling. And SOAPUi has done a great job making your job easy and fun… Almost all of the time.

They have an amazing amount of documentation. I guarantee that everything I am about to tell you is in there somewhere… This is my short story for our case.

So the case is as follows – I have a quite simple WCF service. One trick is that we need to call a common security service (let’s call it SECI) to get a token that we have pass into our operations.

We have worked contract first and started with a WSDL-file. I used (great tool) to generate the service stub. And then…

  • I downloaded SOAPUi. Go on - do it now- it’s free!
  • I created a new project by pointing the wizard to my WSDL-file. I also asked the tool to create a starter testcase for me. Beware of the location or endpoint address – it’s read from the WSDL-file and most likely you will need to change that to your computer or the server where your service is deployed.
  • I then added a new WSDL to the SECI service to the project. This is needed to be able to call

I was now ready to create my test case with the test steps I need to call the SECI service and insert the token into the request I wanted to test.

First I created some parameters for my test suite. This is actually hidden away a bit.

  • Open the test suite editor by right clicking it and chose “Show TestSuite Editor”
  • In the lower section of the editor you’ll find a “tab” that is named Properties
  • Here you can add properties that will be visible for the whole test suite
  • I added some inparameters to the SECI service and the token I will pass on

I then called the SECI service, passing it values from the parameters I created in the earlier step.

To get the values from the response of the SECI service into the request to my service I used a Property Transfer. In it I transferred the value of the token node into a variable that holds the property for the token. It’s a quite deep structure with dropdown boxes and namespaces in the UI here but it’s not to hard to understand.

Finally I could easily insert the value of the token variable into my request, as before.

It wasn’t to hard after I got understanding about the variables for the testsuite. I sure beats having to code your test client manually…

Great work SOAPUi!
