Postman - Can you use the {{...}} syntax within a Test script? - postman

Question

I have an environment variable called "url", the value is a combination of several other variables in the same environment.
Here is the bulk environment variable definition:
scheme:http
server:localhost
port::55881
application:/
url:{{scheme}}://{{server}}{{port}}{{application}}
As you can see, url contains other variables.
This works great in the actual request (I'm using {{url}} when addressing my service), but when I try to use the same variable in my scripted tests (In the Tests tab), I'm getting the un-evaluated version.
var serviceUrl = pm.variables.get("url");
console.log(serviceUrl); //Yields {{scheme}}://{{server}}{{port}}{{application}}
Is there a way to get the evaluated value inside my tests?
Thanks!
Complete test for more insight:
var jsonData = JSON.parse(responseBody);
tests["Status code is 200"] = responseCode.code === 200;
var ordrereferanse = jsonData.Ordrereferanse;
tests.OrdreReferanse = ordrereferanse.length > 0;
//Have to do this
var scheme = pm.variables.get("scheme");
var server = pm.variables.get("server");
var port = pm.variables.get("port");
var application = pm.variables.get("application");
var api_key = pm.variables.get("api_key");
var serviceUrl = scheme + "://" + server + port + application;
//Instead of this - an environment variable defined like this "{{scheme}}://{{server}}{{port}}{{application}}"
//var serviceUrl = pm.variables.get("url");
//remaining test - go to url to verify that the resource is created and the order reference is set
var infoUrl = serviceUrl + "ordreinformasjon/" + ordrereferanse + "?format=json&api_key=" + api_key;
pm.sendRequest(infoUrl, function (err, response) {
var info = response.json();
console.log(info);
tests.OrdreInformasjonOrdreReferanse = info.OrdreReferanse === ordrereferanse;
});

This would work but I'm not sure what you're trying to achieve:
var scheme = pm.variables.get("scheme")
var server = pm.variables.get("server")
var port = pm.variables.get("port")
var application = pm.variables.get("application")
console.log(`${scheme}://${server}${port}${application}`)
That would log out http://localhost:55881/ to the console.
The {{...}} syntax doesn't work in the way that you had it in the environment file. As it's just storing everything as a string so that's why you would get that output.
You could use {{scheme}}://{{server}}{{port}}{{application}} as the URL but not in the tests using the same syntax.
UPDATE
After seeing the update to the question - Could you not combine the separate variables into a single url variable and construct the infoUrl variable in the following way:
var infoUrl = `${pm.variables.get("url")}ordreinformasjon/${ordrereferanse}?format=json&api_key=${pm.variables.get("api_key")}`
Then use a different environment file with the same url key but with a different value if you need to point the request at a staging or production URL.
I've also noticed that you're using the older tests syntax rather than the newer pm.test() syntax, that might clean up some of the code for you.
