Adserver for Testing Server Side Ad Insertion and Impression Tracking

  • Testing server-side ad-insertion (SSAI) stitching as the VAST response from this ad servers always contains ads and creatives.
  • Verify what query parameters are passed from the client device through the SSAI component as this ad server stores all received query parameters for a request (session).
  • Verify that client devices implement correct tracking as the VAST response contains tracking URLs back to the test ad server. All tracked events for a session is stored and can be obtained by the API.

How does it work?

The Ad Server provides a VAST request endpoint that returns a VAST document containing a number of ads and creatives based on duration. The response is deterministic so you know you will always get any ads (which is not the case working with a real ad server) and that the ads contains the right type of creatives.
