An ad test tool allows rich media developers to test ads in both a stand-alone environment and within live web pages. The ad test tool includes a stand-alone ad test tool, a live site ad test tool, and a rules and compliancy engine. The stand-alone ad test tool tests ads in a stand-alone environment by providing the ad rendering framework necessary to render ads on the user's local device. The live site ad test tool tests ads on live web pages. The live site ad test tool includes a proxy that intercepts ad requests from web pages and replaces the ads on the web pages with test ads. The rules and compliancy engine checks test ads for compliancy for security and privacy purposes and also verifies that click tracking and/or impression tracking operate properly.
