If you're deciding between bid types (e.g. CPC and oCPM optimized for an offsite action), you can easily set up an A/B test using the multi-Ad Set uploader in AdParlor. Simply create your desired Targeting Groups then generate two Ad Sets for each, picking a different bid model for each e.g.

Then simply upload the same Creative Groups (i.e. your posts) to the Ad Set pairs and let your campaigns run for enough time to collect significant data. Make sure you spend an equal amount on each Ad Set to ensure that you can perform a fair comparison (e.g. comparing apples with apples).
