A/B Tests not tracking opens or clickthroughs
We are using tracking on A/B testing and it works fine, it might be something about your configuration.

Can you check on the source of the received message if
- the links you put are transformed into something else (ie. if you put google.com, it will be replaced by yoursite.org/sites/all....)
- you have an extra image with a src=yoursite.org/...

if they aren't them, you might have disabled the tracking, could check on the tab in your mailing if they are checked (track open and track clicks?)
