Description:

There are some capabilities described
by the Assembly specification for which there are normative statements
and related Test Assertions,
which are in practice only implemented
by a restricted set of language implementations.

One simple example is the existence
of local interfaces, for which there are a small number of normative statements.
 Since WSDL interfaces
cannot be local, any possible test for
these normative statements must involve using a language specific interface
language such as
Java interfaces or C++ interfaces.

This causes a problem for the TestCase
suite.  It not possible to build testcases for capabilities of this
kind without creating a dependence on
one or more implementation languages,
which is something that the Assembly test suite should not do.  The
Assembly test suite should be
capable of being rendered in any implementation
language.

So, for example, a testcase depending
on local interfaces could not be rendered using BPEL as the component implementation
language since
the only required interface type for
BPEL is WSDL and WSDL cannot represent local interfaces.


Proposal:

One approach to this problem is along
these lines:

1. Mark all test assertions and testcases
which are necessarily implementation language dependent.

2. Remove the requirement to run all
such testcases from the Assembly test suite.

3. Make it a requirement for each language
TC for which a valid version of these testcases can exist to add a version
of each of these testcases
to the language-specific test suite
for their implementation language.

This ensures that whereever possible,
the testcase still exists and must still be run, without requiring testing
the impossible on other 
implementation languages.
