Test Purposes (TP)
6.1
Introduction
For each test requirement a TP is defined.
6.1.1
TP naming convention
TPs are numbered, starting at 001, within each group. Groups are organized according to the TSS. Additional references
are added to identify the actual test suite and whether it applies to the network or the user (see table 1).

The TPs are based on EN 300 064-1 [1].
6.1.3
TP structure
Each TP has been written in a manner which is consistent with all other TPs. The intention of this is to make the TPs
more readable and checkable. A particular structure has been used and this is illustrated in table 2. This table should be
read in conjunction with any TP, i.e. use a TP as an example to fully understand the table.

Test strategy
As the base standard EN 300 064-1 [1] contains no explicit requirements for testing, the TPs were generated as a result
of an analysis of the base standard and the PICS specification EN 300 064-2 [2]. The criteria applied include the
following:
-
only the requirements from the point of view of the T reference point are considered;
-
whether or not a test case can be built from the TP is not considered.

Compliance
An ATS which complies with this TSS&TP specification shall:
a) consist of a set of test cases corresponding to the set or to a subset of the TPs specified in clause 6;
b) use a TSS which is an appropriate subset of the whole of the TSS specified in clause 5;
c) use the same naming conventions for the test groups and test cases;
d) maintain the relationship specified in clause 6 between the test groups and TPs and the entries in the PICS
proforma to be used for test case deselection;
e) comply with ISO/IEC 9646-2 [4].
In the case of a) or b) above, a subset shall be used only where a particular Abstract Test Method (ATM) makes some
TPs untestable. All testable TPs from clause 6 shall be included in a compliant ATS.
