The scope of this standard is the definition of an exchange format, utilizing XML, for exchanging data resulting from executing tests of a Unit Under Test (UUT) via a test program in an automatic test environment. The purpose of this standard is to promote and facilitate interoperability between components of an automatic test system (e.g., between test executive and diagnostic reasoner) where test results need to be shared. The standard thus facilitates the capture of test results data in storage devices and databases, facilitating online and offline analysis. The test results schema becomes a class of information that can be used within the SIMICA family of standards. New IEEE Standard - Superseded.
