1. A computer-implemented method for testing a plurality of candidate creatives, the method comprising: placing, by a media exchange server, the plurality of candidate creatives on a queue coupled with the media exchange server configured to interface prospective buyers and sellers of the candidate creatives; inspecting, by the server, technical attributes of each candidate creative when at a front of the queue with at least one test node before delivery to a publisher, wherein inspecting comprises the server: generating a creative vector containing the candidate creative; launching a browser by a test daemon of the at least one test node; loading the creative vector into the browser; and executing a test suite on the candidate creative by constituent elements of the test node; determining, by the server, that a first of the candidate creatives is a fixed creative comprising constituent elements that do not change each time a creative vector thereof is loaded into a browser; delivering, by the server, the fixed candidate creative directly to the publisher from the server; re-inspecting, by the server, the technical attributes of a second of the candidate creatives that remain in the queue after one or more previous inspections by the server, comprising detecting a hidden technical attribute detectable under unknown specified circumstances; and rejecting delivery of the second candidate creative to the publisher by the server as a result of detecting the hidden technical attribute.
