When testing web services, I constantly find myself needing to run the same set of service test tests against multiple environments.

In order to do this, without having to have the same scripts copied multiple times for each environment, I dynamically set the WSDL's endpoint.

Changing a Service Test's endpoint

Changing a scripts endpoint in Service Test is actually real easy:

• Click on the web service operation in the main canvas area and under its property sheet click on 'General' icon

  

• Notice the Endpoint Address and SoapAction properties -- you can easily point them to either an Input Property that you've created or to a previous action like a Read from File.

How to Setup an EndPoint Input Property Variable

• Click on the 'Start' action

  

• Click on the Start's Property Sheet 'Add Properties' icon and select 'Add Input Property'

  

• In the 'Add Input Property' create a variable named EndPoint:

  

• You should now have an input property:

  

• Navigate back to your operation's 'General' area and for the Endpoint Address click on the 'Link to data source"
• In the Select Link Source to 'Endpoint Address', point to the 'EndPoint' input property we just created

  

  

• Run the script and in the Run dialog click on the Input Parameters tab to set the EndPoint:

  

How to read the endpoint from a file

Another approach is the write out the endpoint to a local file and when the script runs read in the value from the file.

• Add a 'Read from File' activity into the main canvas area
• Under the Read from File's property sheet set the 'File path' to the file that contains the endpoint info:

  

• Navigate back to your operation's 'General' area and for the Endpoint Address click on the 'Link to data source"
• In the Select Link Source to 'Endpoint Address' and point to the read from file's 'Content' output value

  

• Run the script and it should read the endpoint from the file

That's it

Cool! You should now be able to run the same Service Test script against multiple environments.
