4.4.1 Suitability assessment in present test procedures

For test procedures defined within the present document the step table holds a separate column for the "suitability assessment", abbreviated as "SA". It will show the identifier of any conformance requirement (CR) where gaining suitable verification requires the usage of an optional test method. Conformance requirements that can be verified by "implicit" methods, e.g. the usage of a specific value is sufficiently verified if the test proceeds correctly with the next step or if the expected value can be seen on the air interface, will not be listed in the SA column.

4.4.2 Suitability assessment in test descriptions

For each CR listed in the SA column of a test procedure available in the present document additional information about the SA shall be provided with the description of the CR verification.

Tests purposes, conformance requirements and/or procedures defined in TS 31.121 [2] are referenced whenever possible. Modifications needed to adopt a test from TS 31.121 [2] to use the random value generation for the implicit testing will not be explicitly mentioned. If it becomes necessary to add suitable test methods from Table A.2 to a particular CR this shall be done by adding the related information to the related CR in the Acceptance criteria clauses available in the present document.

4.4.3 Suitability assessment in the test protocol

Whenever a test is executed using additional methods to generate a result the method and the gained result shall be noted in the test protocol. Unless otherwise stated in the suitability assessment of the test case, additional measures that lead to results deviating from the results generated by the methods identified to be suitable for this test case cannot contribute to, or influence the result.

4.4.4 Justification of additional measures

Even if implicit verification is recognized as a suitable and appropriate verification method, it is allowed to use additional methods to explicitly verify file contents and/or the file handling. The verification result and the used verification method may be noted in the test report. In case this additional measure leads to a deviating result, the result of the explicit check defined to this test case applies.

Conformance requirements that can be verified with such an additional measure are marked with an ‘O’ in the SA column. Possible optional verification methods are noted in the acceptance criteria for each test case if applicable.
