3.1. Preparation for the testing

The preparation for the testing phase should involve the following activities:

  • production of administrative information;
  • production of ICS and IXIT for testing;
  • identification of test: name, purpose, method, type, testing type and ATS (Figure 2);
  • definition of executable tests adapted to the IUT by selection of initial executive test cases (see point 5.1.4) derived from the abstract test cases and assignment of parameter values based on the ICS and the IXIT;
  • setting up hierarchy and unique identifiers for the abstract and executable test cases ;
  • preparation of the SUT (NOTE This enables a client to run executable test cases on the IUT before presenting the IUT for the test campaign);

3.2 IXIT proforma

The Implementation eXtra Information for Testing is a statement containing all of the information related to the implementation under test (IUT) and its corresponding system under test (SUT) which will enable the testing laboratory to run an appropriate test suite against that IUT and perform correct analysis afterwards. An IXIT typically provides the details on the organization and storage of concepts in the SUT as well as on the means of access to and modification of the SUT.

In the context of LPIS QA, The IXIT probes into eight implementation options that any LPIS custodian must have made at one point to address the choices or options offered by the Regulations:

  • The author/actor of the primary boundary of the reference parcel. The primary boundary or perimeter represents the land corresponding to the reference parcel identifier. The outcome defines the reference parcel type
  • The process that lead to the delineation of the physical borders of the agricultural land to be used as maximum eligible area.
  • The way the eligible landscape features, if applicable, have been adjudicated to the reference parcel
  • The processing of the spatial themes above to assemble a maximum eligible area for each individual reference parcel perimeter
  • The application of pro rata reduction of permanent grasslands with scattered ineligible features
  • The validation and documentation of the required positional accuracy requirements.

These issues are addressed under IXIT rather than the ICS below or than metadata because the IXIT results play an important role in the inspection procedures and automatic screening of the annual data value tests.

The procedure to test, document and report these 8 choices are described in the separate document: annex X TG IXIT. Please follow the instructions of this TG IXIT in Annex X.

3.3 ICS proforma

The implementation conformance statement (ICS) provides a statement of the options available in the LCM which have been adopted by a particular implementation. The ICS provides a better understanding of the LPIS implementation under test (IUT) and helps to identify the boundaries of the testing domain. ICS can describe the specific options implemented in the IUT that serve as a basis for the adaptation of the initial executable test cases (see point 5.1.4). These relevant options are only those specified within the framework of requirements in the LCM.

Since the particular implementation options can be reflected in the revised executive test cases, the provision of the ICS document is optional.

3.4 Other IXIT/ICS-related information components

There are two other LPIS QA information components that are not in the scope of the IXIT and ICS, but are part of the MTS 2.0 since they provide other essential information on the choices and lineage regarding the IUT:

  • The eligibility profile which provides an LCML -compatible catalogue of the land cover classes deemed eligible by the LPIS custodian. The eligibility profile methodology and format are described in Annex III of the TG ETS.
  • Metadata on the source and reference datasets involved in the assemblage of the reference parcel with respect to perimeters and borders (see Annex X IXIT). This particular metadata is sufficiently structured by the INSPIRE implementing rules on metadata and the relevant data specifications. The selected metadata elements relevant for MTS are given in tables 2 and 3, as well as separately in Annex XI (MTS log).
