Thread on EFI Updater (for Internet Recovery/AHT) not applying in OS X 10.10:
I suspect most 2010/2011 mac owners already applied the EFI update for OS X internet recovery when it was released several years ago, but an Apple forum thread on Mac Mini 4,1 (mid 2010) - Hardware test unavailable includes notes from the mini owner (now running OS X Yosemite) that hadn't applied the Mac mini (Mid 2010) EFI Firmware Update 1.5 (posted Jan 2012) for OS X Internet Recovery support (ref: About the "Apple Hardware Test does not support this machine" message) and said the firmware updater will not run in OS X 10.10. (Hopefully he has a clone of his older OS X install to boot from to apply the update. I've used Disk Utility's 'Restore' tab to create complete bootable clones as I don't own CCC or other utilities.)

I'm not running OS X Yosemite (nor a mac that needs an earlier posted firmware update) to see if this is common but just a reminder to check/apply updates like this before doing a major OS X upgrade. Sometimes updaters may be revised for compatibility with later OS X versions, but not always. (This Apple doc has a list of EFI updates for 2010/2011 Macs to add OS X Internet Recovery and here's a complete list of EFI & SMC firmware updates for Intel-based Macs.)
