Intel has a device to help with UEFI testing, the Intelligent Test System (ITS). ITS may have been around for a while, but I just noticed it on the Intel firmware web site. I’m presuming for now that it’s new from IDF, but I may be wrong about that. If you do UEFI testing, you might want to look at this device.
I wonder how it compares to Linaro’s LAVA. LAVA does mostly target ARM devices, but does also target Intel via QEMU, perhaps there are direct Intel targets these days.
