Each ConformanceUnit represents a specific set of features (e.g. a group of services, portions of services or information models) that can be tested as a single entity. ConformanceUnits are the building blocks of a Profile. Each ConformanceUnit can also be used as a test category. For each ConformanceUnit, there would be a number of TestCases that test the functionality described by the ConformanceUnit. The description of a ConformanceUnit is intended to provide enough information to illustrate the required functionality, but in many cases to obtain a complete understanding of the ConformanceUnit the reader may be required to also examine the appropriate part of OPC UA. Additional Information regarding testing of a ConformanceUnit are provided in the Compliance Part 8 UA Server or Compliance Part 9 UA Client test standards.
The same features do not appear in more than one ConformanceUnit.
