This document describes an integration test framework for demand-side platforms (DSPs) and supply-side platforms (SSPs). It includes classes for: 1. Creating test requests with different parameters like IP address or mobile carrier. 2. Sending requests to SSPs/DSPs and capturing responses using a shared context object. 3. Testing responses by validating expected properties like no bid responses. It also shows how to initialize a shared browser instance and ensure it is closed on JVM shutdown to clean up resources.
