Unlike most MIPI Alliance working groups, the Test Working Group itself does not produce any specifications. Instead, it functions in an advisory role for all MIPI Alliance working groups that do develop specifications. It promotes an awareness of test issues and encourages development of test-related materials.

The Test Working Group also advises the MIPI Alliance Board of Directors on all test-related issues and conformance questions. It encourages members to participate in conformance and interoperability test activities.
