How to insert a DEFAULT custom header value to all SoapUI projects? - groovy

Question

We have SoapUI (Open Source Edition) installed on a windows jumpbox. Many users can login with their accounts, open soapui, import a wadl/wsdl from a dozen of projects and perform testing.
Since the IP is always same, we are unable to find who has sent a request and that is a problem when some destructive requests are made that causes lots of recovery issues (Only authorized users have the access).
Now we want to add http header like user : ${=System.getenv("USERNAME")} to the request. It can be a new header property or even a part of user agent.
We tried to put the property inside HTTP Preferences as a part of user agent string, but it passes the parameter as a string
We also set a global property but couldn't find a way to insert it as one of HTTP calls by default.
The only ways we found so far was:
going to soapui setting of each user and add headers to all requests one by one. (problem: what if user imports more wsdl/wadl later)
adding a startup script to created projects, so it adds the header by default to everything (problem: users can create new projects any time - please note that each soapui instance is individual)

This requirement can easily be fulfilled by the SoapUI's pro software using the feature called Events.
For example, add the header for each request before submitting the web service / rest service call.
However, you mentioned that free version is being used. Wrote an extension some time ago, which allows us to do the same in the free edition of SoapUI. There is a readme available explaining how to use this. Basically this extension implemented the some of the listeners of SaopUI's API while providing the flexibility to the end users what code should they run(in the form of external file) when the respective event occurs.
Complete the instructions mentioned in the readme.
Then you need to do is write a groovy script(already given below) to implement your requirement i.e., add the header to the request. That needs to be done in a file with specific file name located in specific directory(details available there).
In your case, the required code(mostly working sample below) should go into file called RequestStepBeforeSubmit.groovy, in order add the user name into each request's header automatically.
Below code snippet should work even if you use the pro software for the same requirement when SubmitListener.beforeSubmit event happens.
//change the condition if required, should be working for soap/rest types
if (context.getProperty("wsdlRequest")){
def request = context.getProperty("wsdlRequest").testStep.httpRequest
def existingHeaders = request.requestHeaders
def username = System.getProperty('user.name')
existingHeaders['user'] = [(username)]
request.requestHeaders = existingHeaders
}
