Plugtest
PlugTest or PlugFest is a term used about an event around a certain standard where the designers of electronic equipment or software test the interoperability of their products or designs to other vendors. It could be quite literally be 'plugging' vendor A's cable in vendor B's socket, or a more elaborate test resembling a realistic scenario.
For example CEA organizes PlugFests for interoperability testing between HDMI, sink and repeater devices. In the similar way VESA organizes PlugTests for DisplayPort device designers and vendors. Similar PlugTests are organized to e.g. USB device vendors.
The technical goal is twofold: check compliance to the standard, and test the effectiveness of the standard. The latter could be the case when the standard is ambiguous. A simplified example is: the width of a plug is prescribed but vendors use different lengths.
Plugtests can be formal and have public test scores or informal and private. Besides helping vendors improve their interoperability, plugtests facilitate in creating awareness about the standard and can improve transparency on compliancy.[1]
