Hi,
I am having problems trying to use collection variable as an assertion in a test. I think my syntax is off.
Collection variables:
I try to get the variable with:
pm.collectionVariables.get(“createdSegmentId”) //i’m not sure if it should be with or without quotes
I try to use it later with:
pm.expect((jsonData.data.createLp.segmentId)).to.equal(createdSegmentId) // i’ve tried with and without {{}} around variable name
In the end I get an error:
ReferenceError: createdSegmentId is not defined
thanks for any help

Hi @timothy.jahn! Welcome to the Postman forum and community! 
The issue here is that you have used the pm.collectionVariables.get method, but you didn’t actually retrieve that value and assign it to a local variable. So in line 16, there’s no local variable actually called createdSegmentId. If you change line 14 to say the following, it should work:
let createdSegmentId = pm.collectionVariables.get("createdSegmentId");
Another option would be to avoid setting a local variable. To do that, you can retrieve the value of the collection variable directly in line 16 with the following:
pm.expect((jsonData.data.createLp.segmentId).to.equal(pm.collectionVariables.get("createdSegmentId")));
Hope that helps!
