all the entities at receiving side are subscribed to the same ERDS.
- Environments that correspond to the 4-corner model as defined in ETSI EN 319 522-1 [1] where sender
is subscribed to one ERDS and the entities at receiving side are subscribed to another one, and no
intermediate ERDS is required for relaying ERD messages between them.
- Environments that correspond to the extended model as defined in ETSI EN 319 522-1 [1] where sender
is subscribed to one ERDS and the entities at receiving side are subscribed to another one, and
intermediate ERDSs are required for relaying ERD messages between them.
2) A mechanism for documenting new test cases and expanding the aforementioned test suite.

4 Technical approach
4.1 Components of test cases and their identifiers
As it has been mentioned before the present document defines:
1) A test suite for supporting interoperability tests within the field of Electronic Registered Delivery (ERD
hereinafter) as specified in as specified in ETSI EN 319 522 parts 1 [1], 2 [2], 3 [3] and 4 [4], [5] and [6].
2) A mechanism for documenting new test cases and expanding the aforementioned test suite.
The present document follows a layered approach for building the definition of the test cases in the test suite, which can
be summarized as follows:
1) Clause 5 defines a number of parameterized scenarios. A scenario consists of a number of entities, namely:
sender, one or more ERDSs, and the entities at receiving side (one or more recipients and/or one or more
recipients' delegates), which exchange different ERD messages with time. Each scenario corresponds to one of
the three models presented in ETSI EN 319 522-1 [1]. This clause presents a template for defining one
scenario, in a way that resembles to some templates used for defining use cases scenarios in software
engineering.
This template:
- Includes the enumeration of the original message and all the ERD messages exchanged by the
participating entities. This list of exchanged ERD messages is one of the parameters of the scenario.
- Also includes a list of ERDS evidence sets, which, in the scenario, are incorporated in some ERD
messages.
One scenario may be used for defining several test cases depending on:
- The specific components of each exchanged ERD message (suppressing or adding an optional metadata
component, or changing the value of a certain metadata component results in a different ERD message
and consequently a different test case).
- The entities at receiving part (for instance, changing one recipient by one recipient's delegate, or two
recipients and one recipient's delegate results in a different the test case).
- A named set of additional requirements (for instance details of the original message, like whether it
contains or not attachments, is signed, is encrypted, etc.).
This means that one test case corresponds to one scenario where all the exchanged ERD messages have been
completely defined in terms of their components, all the participating entities have been established, and all the
additional requirements have also been defined. Taking the functional notation this can be expressed as
follows:
TestCase#i = Scenario_id(,, , details>, …, , Where:
- is the identifier assigned to a certain set of entities at receiving side;
ETSI

---------------------- Page: 8 ----------------------
9 ETSI TS 119 524-2 V1.1.1 (2019-02)
- is the identifier of a specific instantiation of the aforementioned message, defined
in clauses 6.3, 6.4 and 6.5. These clauses define specific instantiations of ERD payloads, ERD receipts
and ERD dispatches respectively.
- is the identifier of a named set of additional requirements.
Clause 7.2 defines a number of these named sets.
2) Clauses 6.3, 6.4 and 6.5 define specific instantiations of ERD payloads, ERD receipts and ERD dispatches
respectively. Each type of ERD message is composed by several components, with their metadata components
and payloads as specified in ETSI EN 319 522-4-1 [4] and ETSI EN 319 522-4-2 [5]. The present document
defines a number of combinations of metadata components in clauses 6.2.2 and 6.2.3, and assigns to each one
a unique identifier. This allows to use again the functional notation, and define one instantiation of a certain
type of ERD message as follows:
ERD message instance = Sequence(Metadata(, for ERDS relay metadata combination details>) * Evidence>*)
Where '*' stands for 0 or more occurrences of the payload.
NOTE: The payloads for user content and for ERDS evidence can be present at certain types of ERD messages
but are forbidden in other types.
3) Clauses 6.2.2 and 6.2.3 define named combinations of metadata components defined in OASIS: "AS4 Profile
of ebMS 3.0 Version 1.0" [8] and profiled in ETSI EN 319 522-4-1 [4] and ETSI EN 319 522-4-2 [5], and the
relay metadata components defined in ETSI EN 319 522-3 [3] respectively. Each clause define different
instances of the aforementioned components and assigns them unique identifiers that are used for defining
specific instances of the different ERD messages as shown above. Once this level is reached, the specific test
case is fully defined as: a scenario where fully defined, ERD messages are exchanged between a specific set
participating entities, and where a specific set of additional requirements are imposed.
4.2 Adding new test cases to the test suite
The strategy followed for building the definitions of the test cases makes it easy to expand the test suite by
incorporation of new test cases.
For defining a new test case the following steps are required:
1) Identify the set of receiving entities. If none of the predefined set of entities at the receiving side is the one
required, assign a name to this set () and incorporate it to the repertoire of
named sets as specified in clause 7.3). The sender is always present by default.
2) Define the ERDSs that will participate in the test case.
3) If the set of participating ERDSs is not equal to none of the scenarios already identified in the present
document, the new scenario will require to be defined in a new template.
4) Identify the sequence of actions performed by each actor and their order of occurrence and assign a new
unique identifier () to the scenario.
5) Identify all the ERD messages generated by the actors as they go through the sequence of actions. For each
message:
a) Identify its ebMS payloads, e.g. the parts of the user content or XML document with relay meta-data.
b) Check if the combinations of metadata components have already been defined in the present document.
If not, add the required combination of metadata components to the repertoire of named combinations to
the corresponding clause (clause 6.2.2 or 6.2.3).
c) List all the ERD messages exchanged as parameters of the scenario.
d) Identify the ERDS evidence format and the set of ERDS evidence for each ERD message including them
and add the names of the ERDS evidence sets to the Var section of the template.
ETSI

---------------------- Page: 9 ----------------------
10 ETSI TS 119 524-2 V1.1.1 (2019-02)
6) Identify and define any other additional requirement for completely define the test case. If the set of
requirements is different than all the sets already define, assign a name to it () and add
it to the repertoire of named sets of additional requirements in Table 12 (clause 7.2).
5 Scenarios
5.1 Introduction
The present clause defines a number of selected scenarios that will be used in clause 8.
Clause 5.3 defines scenarios where sender and recipient(s) are subscribed to the same ERDS (black-box model
described in ETSI EN 319 522-1 [1]).
Clause 5.4 defines scenarios where the sender and the recipient(s) are subscribed to different ERDSs and there are not
intermediate ERDSs between them (4-corner model described in ETSI EN 319 522-1 [1]).
Clause 5.5 defines scenarios where sender is subscribed to a ERDS and the recipient(s) is(are) not subscribed to the
same ERDS and there are one or more intermediate ERDSs (extended model described in ETSI EN 319 522-1 [1]).
Figure 1 of clause 4 of ETSI EN 319 522-2 [2] shows three structures being exchanged between ERD-UAs and ERDSs,
namely:
1) The structure {submission metadata, user content}, which receives the name of original message in Table 1 of
clause 4 of ETSI EN 319 522-2 [2].
2) The structure {ERDS handover metadata, ERDS evidence} for allowing access to ERDS evidences to users.
3) The structure {ERDS handover metadata, user content, ERDS evidence} for allowing the R-ERDS the
submission of the user content (and optionally ERDS evidences) to the recipient.
Because of that the following decisions have been adopted for building the scenarios:
1) Neither S-ERDS nor R-ERDS will submit {ERDS handover metadata, ERDS evidence} structures to their
users, except when the ERDS evidence is an evidence of some kind of relevant rejection by the ERDS (see the
first scenario, for instance). Identical scenarios including the submission of such structures can be easily
defined and used in interoperability test events.
2) The scenarios will show the R-ERDS submitting {ERDS handover metadata, user content, ERDS evidence} or
{ERDS handover metadata, user content} structures to the receiving side.
3) The acronym hndvMet is used for ERDS handover metadata.
Table 1 shows the template for defining one scenario.
