Subject Proposal for a (Java) community test suite for SDO
Date Thu, 30 Nov 2006 17:43:59 GMT
I would like to propose starting a community test suite for service data
objects (SDO CTS) implementations written in Java. Based on feedback from an
earlier post this seems to be the first logical step in getting
interoperable SDO implementations in all languages. I can see this leading
to an interoperability test suite to check serialisation between
implementations also works (across languages and implementations).

Proposal for Community Test Suite (CTS) for SDO
Develop a test suite to validate an SDO implementation behaves as expected,
according to the community's understanding of the SDO specification. Should
the specification appear ambiguous or unclear then the community will decide
what to do; it may decide to test the area with an agreed expected
behaviour, or decide not to test this area. Ambiguities will be fed back to
the specification group for clarification. Although we will run this against
Tuscany, the test suite will only test things that we think any
implementation should support.

The SDO CTS will enable developers to choose or switch SDO implementations
without the concern of having to re-code a significant proportion of their
application due to differences between implementations. This community test
suite will first  focus on areas identified important to developers of SDO
applications. SDO users feedback and involvement will be crucial to the
success of this effort. Over time this may grow to include a large
proportion of the SDO specification, however the suite should grow according
to the community's desire, rather than attempting to be a validation or
compliancy suite.

To encourage everyone with an interest in SDO to contribute and use the
suite, I propose we :

   1. Create a separate module in SVN to separate this from Tuscany
   components and testcases.
   2. Make use of a java package namespace that is not attributable to
   either Tuscany or any other SDO implementation: test.sdo
   3. Refactor some of the existing Tuscany SDO Java test cases to remove
   any Tuscany specific coding and re-package these to the test.sdo
   namespace.
   4. Accept tests from anyone who wishes to contribute them under normal
   Apache contribution conditions.


SDO users involvement will be crucial to this effort, developers of SDO
implementations will benefit by contributing to and consuming a community
test suite, rather than working on their own.

Who's up for working on this with me ?

If you are interested in joining this effort; have any concerns, comments or
suggestions please append them...

Thanks in advance to all those who volunteer :)
