The Test Working Group does not arrange test events directly but strongly advocates that members hold conformance testing events and/or interoperability testing events (a.k.a. “plugfests”) to facilitate convenient product testing or to determine how well their products work together. 

The Test Policy approved in 2016 allows and encourages MIPI Alliance working groups to organize these test activities. All members, particularly independent test labs and test services companies, are also encouraged to organize events.
