I have an API URL like http://example.com/images/crop.png.transform/pictures/image.png which returns only an image. The content type is image/png.

I need to write a postman test to make sure the image height and width are what's required. I tried with the following code but gets the error "There was an error in evaluating the test script: ReferenceError: document is not defined"

pm.environment.get("image")
var url = document.createElement("img");
url.src = pm.environment.get("image");
tests["url width"] = url.width === 640;
tests["url height"] = url.height === 960;

You're adding an image element but based on the code shown you haven't added a source for the img. – displacedtexan Feb 21 '20 at 19:34

There is no `document` in the Postman environment. See [the documentation](https://learning.postman.com/docs/postman/scripts/postman-sandbox/) – Heretic Monkey Feb 24 '20 at 22:24
