    810There are numerous industry and country specific standards for safety including [http://en.wikipedia.org/wiki/DO-178B FAA DO-178B] for flight software in the United States.  There are similar aviation standards in other countries as well as in domains such as medical devices, trains, medical and military applications.  As a free software project, the RTEMS Project may never have a complete set of certification paperwork available for download.  But we would like to ensure that RTEMS meets the technical requirements that are shared across these safety and quality oriented standards.

    16 In order to achieve the 100% tested goal, it is important to define what constitutes 100% tested.  A lot of information exists about how to completely test a software application.  In general, the term [http://en.wikipedia.org/wiki/Code_coverage Code Coverage] is used to refer to the analysis that is performed to determine what portions of the software are tested by the test suite and what portions are not tested.  It should be noted that Code Coverage does not prove correctness, only that all code has been tested.  For some background information on Code Coverage Analysis, see [wiki:Developer/Coverage/Theory Coverage Analysis Theory].

    1820Traditionally, Code Coverage Analysis has been performed by instrumenting the source code or object code or by using special hardware to monitor the instructions executed.  The guidelines for the RTEMS code coverage effort were to use existing tools and to avoid altering the code to be analyzed.  This was accomplished by using a processor simulator that provides coverage analysis information.  The information was processed to determine which instructions are executed.  We called this Object Code Coverage and we defined 100% tested to be 100% Object Code Coverage.
