TestConfiguration schema will encompass all information necessary to identify all of the hardware, software and documentation that may be necessary in order to test and diagnose a Unit Under Test (UUT) on a test station. There may exist multiple TestConfiguration documents for a given UUT. Identifies the activity responsible for maintaining configuration management of the UUT and TPS. Identifies the UUTs to which the configuration data applies. Multiple UUTs can be listed in the case where the configurations are identical. Collector element forTest Equipment Items Identifies the family of test stations that are able to test the UUT. Multiple stations can be listed that support the same UUT using the identical resources. The specific versions of test station software that this UUT is known to work with. The test station assets required to test the UUT. Other non-instrumentation items required by the test station to test the UUT, such as extra cables, adapters, etc. Identifies all of the test program related hardware, software, and documentation. References to TPS hardware required to test the UUT, such as the Interface Test Adapter, cables, holding fixtures, etc. The specific versions of test program software used to test the UUT. References to test program related documentation, such as Theories of Operation or Test Program Instructions. Other software, not typically classified as test program software, to be used to test the UUT, such as Operational Flight Programs. Additional hardware, not part of the test station, required for testing the UUT, such as unique personnel, roll-up test equipment, etc. Managed point of extension. Base type for some TestConfiguration hardware references. base type for TestConfiguration software elements. Optionally allows the method used to compute the checksum (i.e. MD5). specifies the specific value of the checksum
