Summary | 0005417: Support of parametrized map/unmap operation for full dynamic mapping

Description

In many situations in the testing world configuration parameters for connections are needed in the real world.
In TTCN-3 the establishment of a connection is announced by using the map operation. This allows dynamic mapping inside the behaviour of a test and should be an advantage in comparison with TTCN-2.
Currently this can be used in all cases where no additional configuration parameters are needed for establishing a connection(in the adaptation). In some cases static configuration parameters like property files are efficient enough, however for fully dynamic configuration and establishing of connections an extension to the existing map operation is needed.
We propose to extend the existing map operation with an optional parameter containing a configuration value. Attached you will find the modified recommendation including proposals for the map statement and additionally for the port type declaration.
The benefit of the proposal would be the full support of dynamic configuration!
We include the modified recommendations for reference(including change bars).

Steps To Reproduce |
Additional Information | A short example of our proposal: var MyConfigType MyConfig := { option := 1, lock := false}; : map(mtc:Port4, system:PCO2) param MyConfig); type port PortTypeIdentifier message "{" { ( in | out | inout ) { MessageType [ "," ] }+ ";" } [ map param "(" FormalPar {"," FormalPar} ")"] [ unmap param "(" FormalPar {"," FormalPar} ")"] "}"

Needs to be discussed in relation to 5224, hence postponed to 2010.

uploaded corrected versions of part 1 and 3. No corrections for part 4 were necessary. Ready for integration into the standard, if approved.

It is OK up to know, some addition is needed: we specify all "parameterizable" objects and forms of parameterization in clause 5.4, this should also be included there.
I haven't seen the statement the map and unmap operations shall have in value parameters only.
CR5224 on dual-faced ports are set as a related CR but there is only a loose connection between them. CR5224 is about handling situations like this:
1) User tests something above TCP transport and obviously using a TCP adapter. His/her test cases and test data are using the ASPs of the TCP adapter. Then the SUT changes and he/she has to execute the same test cases using e.g. SCTP transport. The SCTP adapter has different ASPs defined than the TCP adapter. In this case the mapping between the two sets of ASPs could be done in a dual-faced port, instead of re-writing the already verified and running test cases.
2) Protocol A carries encoded messages of protocol B, for example a web application carried by SOAP carried by HTTP over TCP. The user is testing the application but from the point of view of the test system, HTTP (or SOAP in case of an HTTP adapter) is the "upper layer protocol", CD will encode/decode only HTTP (or SOAP) messages but not the Application messages. This means that from the point of view of the user no matching is possible by a receive statement (as he/she wants to match the Application messages, which are embedded in an encoded form in the received SOAP or HTTP messages). Dual-faced ports it can handle the whole encoding/decoding chain, i.e. mapping Application ASPs to SOAP/HTTP ASPs and calling external functions for message encoding/decoding, thus the user would be able to send/receive the Application messages directly in his/her test case code.
These are real-life examples, coming from everyday practice. The problem is so real that Titan has implemented a vendor-specific solution for the problem.

both in and out value parameters are allowed by the proposal. The restriction to value parameter unfortunately can only be seen in the BNF and syntactic description, so maybe this should still be added as a restriction.
The relation to CR5224, though loose, is still there and thus needs to be considered (there), as for port composition, of course, the map/unmap parameters also need to be translated.

in Part-1: change the BNF that address, map param, unmap param, in/out message lists could be in any order. Part-5 and part-6 portions to be completed.

25-05-2011 07:41

changed es_20187301v040101p_crMapParam.zip and core.bnf to allow Port Attributes in any order. added 3 new rules in core.bnf at the end (because of numbering), please use the tool to shift them to the right position (if possible) I designed the rules in a way that also easily allows adding additional port attributes to be added (i.e. the address type from CR2105)

I've changed the Product Version to 4.3.1 as 4.1.1 was obviously wrong (at least it cannot be found in 4.1.1 or 4.2.1, but can be found in 4.3.1.) I think we should include the still necessary changes also in 4.4.1 (or whatever the next interim version is called) as up till now this is inconsistent grammar-wise in the 4.3.1 version.

TCI extension updated: - TCI operations take tciParameter - Logging operations log also potential encoder failures - parameter names unified: parameterList for tciParameterList and tciPars/triPars for logging operations Please check es_20187306v040101p_crMapParam_v2
