Description of change

This PR adds the eplanningBidAdapter, which was removed because the old version did not comply with the new 1.0 requirements.

• test parameters for validating bids

var adUnits = [{
    code: 'div-gpt-ad-1460505748561-0',
    sizes: [[300, 250]],
    bids: [{
      bidder: 'eplanning',
      params: {
        t: 1
      }
    }]
}];

Other information

The bidder parameters have not changed so the documentation doesn't need to be updated.
An important note: the adserver code needs a small update (it will be done in the next few days) before it can correctly answer in the format the adapter expects (the test adunit does work correctly, though), I'm submitting the PR now so we can be sure the adapter is correctly verified.

Thanks!

Hi @dbemiller, could this be reviewed? I know you are busy but we would like to be compatible with 1.0 asap

[dbemiller]

@sebaperez I do minimal work on Prebid.js these days... my main focus is on Prebid Server.

Most everyone involved on both projects was out last week, but one of the Prebid.js maintainers will get to it whenever they have bandwidth.

The user sync generating a 404 because the url is being set to the string 'sync' which causes the browser to try load an object called 'sync' relative to the current page

        syncs.push({
           type: 'image',
           url: 'sync',
          });

The other thing I noted, the returned test ad is just text. Most adapters test ad is an image

[Nistenf]

@mike-chowla Thanks for the feedback. I just fixed the sync, and changed the test ad to an image (this needs to be deployed)

[mike-chowla]

Doesn't look like the test ad image deployed but otherwise looks good

[mike-chowla]

With fixes looks, good.

[sebaperez]

@mike-chowla thank you so much for reviewing!
Can we move foward with this? The image ad for testing will be deployed in the following days. However seems that the code itself is OK. Forgive me for insisting, but we really want to be compatible with 1.0

[mike-chowla]

@sebaperez, I've already enter my review as 'approved' so you are good from my end. I understand waiting to get your 1.0 code out :-)

LGTM

Added the needs-docs label since it's not showing up on http://prebid.org/download.html in the 1.2.0 dropdown due to lack of the page having the "prebid 1.0 support" key in the page's YAML header.

@rmloveland I just opened a pr in prebid.org website repo (ref prebid/prebid.github.io#586)
