API Testing of Dynamic Ad Placement Response

The response being evaluated is a JSON format sent back from a server, which outlines the setup for an advertising module tied to a specific placement (PLACEMENT_100916). This module, known as HTML_MODULE, includes both HTML and JavaScript components to dynamically display an ad on a webpage. The HTML part defines where the ad will show up, while the JavaScript contains an external script URL along with inline code that sets various ad parameters, such as the placement ID, provider info, ad dimensions, refresh options, and tracking headers.

The test script in Postman checks that this response is complete and properly formatted by looking for essential elements, including a successful status code (200), the existence of the main modules object, the accurate setup of PLACEMENT_100916, and specific parameters in the inline JavaScript (like providerParameters for tracking and refresh headers). These tests confirm that the ad configuration is clearly defined and ready for deployment in a live environment.
