User-defined script library


I have some scripts that I have written myself that perform parsing and assertions on responses and I reuse these in multiple requests. Currently I am copying and pasting each of these scripts into each test. It would be nice to have the functions declared in a central library so I don’t have to manually update each collection/folder/request where they are declared.

I figured that maybe declaring a function on the collection level would make it available for a request within that folder, but no such luck. From the Postman Console:

ReferenceError | parseResponse is not defined

Is it possible to reference in a user-defined collection of functions?


This is a really good idea. You should submit a feature request on GitHub

So not currently supported, then :slight_smile:


I do this by running something in the test script for the collection that defines a global variable, then I can reuse in my tests.
In the collection scripts:

postman.setGlobalVariable(“DoAThing”, (Variable) => {
//do some stuff

And then in the specific tests as:

It’s not great, and eval isn’t a great thing to use, but it saved me a lot of time compared to changing stuff directly in loads of individual tests!
