mocking dsp's in header bidding

Question

is it possible to hard code the return from the bidders in header bidding , like is it possible to mock the function of bidders like appnexus and other for learning and playing around ? like a bidder generally returns :

adunit aId bidder time cpm "QzxcU6" "106oF" Appnexus 400 0.082367

Answer 1

You would have to modify the modules in prebid in order to get them to work like that. Generally if you want to test things I'd recommend running a house campaign to those placements (or via a segment pixel segment).

You could then use a bid CPM adjustment in pbjs.bidderSettings to set the values returned to be a particular price if you'd like

Answer 2

option 1

If you just want to play with it in your browser you can simply change requested domains in your /etc/hosts file to point at your localhost and bring up a local server serving the response you need.

option 2

you can download prebid.js, patch locally whatever you need and build your own version

option 3

If you need it for tests just check out how other tests are written i.e. appnexus's ones
