@mkendall07 , Getting this error on Travis
Cannot start ChromeHeadless

Could you check ?
Thanks.

[mkendall07]

the issue is on travis side. You'll need to rebase off master to get travis working again since I just merged a workaround

@vedantseta When testing this adapter with the provided bidder parameters, was getting a CORS error at first but that seems to have been resolved. However, am now getting back empty bids with no_bid: true status. Please check and advise how to test for valid bids and then I'll continue with the review, thanks

@matthewlane Thanks for taking a look at the adapter. A campaign needs to be active / setup for a bid to be returned. You can use the following for a successful bid.

      var adUnits = [{
        code: 'div-gpt-ad-1460505748561-0',
        sizes: [[300, 250], [300,600]],

        // Replace this object to test a new Adapter!
        bids: [{
          bidder: 'medianet',
            params: {
              cid: '8CUX0H51C',
              // Site member is to be used only for testing
              site: {
                  page: 'http://smoketesting.net/prebidtest/',
                  domain: 'smoketesting.net',
                  ref: 'http://smoketesting.net/prebidtest/'
              }
            }
        }]

      }];

I've been checking it on http://localhost:9999/integrationExamples/gpt/hello_world.html and I'm successfully getting bids.

Params are returning bids now, thanks. LGTM
