Executive summary
The present document is providing a detailed description of the implementation of the NGSI-LD Test Suite. It describes
the architecture of the Test Suite, then goes into the details of the source code structure, the tests interfaces and the tests
libraries.
Introduction
The ISG CIM group has defined an API for exchange of information contextualised in time, space and relation to other
information using a property graph model with the intent that the associated protocol (called NGSI-LD) becomes the
"glue" between all kinds of applications and databases associated with services for Smart Cities, Smart Agriculture,
Smart Manufacturing, etc.

5 ETSI GS CIM 014 V2.1.1 (2024-04)
To be successful, the NGSI-LD API specification needs to be well understood and well implemented. The community
of users will not be solely highly professional engineers employed by big companies but will include many small teams
and SMEs and even hobbyists. Therefore, it is essential that the developers have access to not only the standard but also
a test specification and a testing environment to check that their work is (and remains) conformant to the ETSI
NGSI-LD specification.
The developers will usually write integration tests to validate the behaviour of their NGSI-LD implementation, but it is
important to assert compliance to the specification based on a Test Suite agreed by the group creating the API
specification, i.e. ETSI ISG CIM. Therefore, it is very important to create a set of ETSI-approved test cases.
What is more, the existence of such a Test Suite will likely help to increase the adoption of the NGSI-LD specification
by giving developers a ready to use and complete set of sample requests.
The present document describes the general architecture of the Test Suite, the overall organization of the source code,
the tests interfaces, the tests framework components, then the tests strategies. It concludes with a list of identified
untestable Tests Purposes.

1 Scope
The present document defines the organization or grouping of test cases based on the functionality to be tested
(e.g. registration, subscription, query, etc.) and - most importantly - selects minimal subsets ("narrower scope") of
functionality to permit testing of the main features of an operating NGSI-LD system.
