[ASSEMBLY-206] Test 5032 and 5034 uses runtime-specific URIs - PROPOSAL

Folks,

ASSEMBLY 206 shows a problem with a
couple of the Assembly testcases that use explicit Web service endpoints
as part

of the testing of the handling of Bindings.
 The problem is that actual endpoint addresses are currently contained
in the 

composites that belong to the testcases
- but these endpoint addresses are likely to change from one SCA runtime
to another.

The proposal made here is to parameterize
the endpoint addresses using XML Entity References and to declare values
for

those Entity References in a separate
file (a DTD file) and to allow SCA runtime vendors to modify the contents
of the separate

file to reflect appropriate values for
the Web services endpoints.

This approach is chosen to avoid the
main files under test (the composite files) from being modified - such
modifications would

set a bad precedent that could lead
to the testcases being subtly subverted.  This proposal ensures that
modifications are only

permitted in a carefully controlled
way in very limited places.

So, let's take ASM_5034 testcase as
an example.

In the current version, the composite
has a reference that uses an explicit Web service address:

        <reference
name="Reference1">

         
      <interface.wsdl
interface="http://test.sca.oasisopen.org/#wsdl.porttype(Service1)"/>

         
      <binding.sca
uri="TestComponent2/Service1"
name="first"/>

         
      <binding.ws
uri="http://localhost:8080/TestComponent2/Service1/second"
name="second"/>

        </reference>

...note the uri value of the binding.ws

The first part of this proposal changes
the explicit Web service address for an entity reference:

        <reference
name="Reference1">

         
      <interface.wsdl
interface="http://test.sca.oasisopen.org/#wsdl.porttype(Service1)"/>

         
      <binding.sca
uri="TestComponent2/Service1"
name="first"/>

         
      <binding.ws
uri="&ws_addr_5034;"
name="second"/>

        </reference>

....note the &ws_addr_5034; entity
reference

The second part of the proposal is to
add a reference to an external DTD file at the start of the composite (before
the <composite> element):

<!DOCTYPE
sca_assembly
SYSTEM
"sca_variables.dtd">

...note that the form of the URI for
the DTD implies that the file is in the same directory as the composite
file (they are all in the base of the

General contribution in this case)

Finally, the third part of the proposal
adds an external DTD file, sca_variables.dtd, into the set of artifacts:

<!--

 * This DTD forms
part of the SCA Assembly Test Suite.

 * It declares a
number of XML Entities which are used in Entity References in some of the

 * composites that
are artifacts used in the testcases.

 *

 * The values declared
in the Entity References are intended to reflect SCA runtime specific

 * values for certain
aspects of the composites at runtime - in particular addresses of some

 * services.

 *

 * It is permitted
- indeed it is expected - that an SCA runtime provider will MODIFY the
values

 * declared for
the Entity References to match the values which would be expected when
running the

 * SCA Assembly
test suite against a given SCA runtime.  The values held in the this
file are

 * examples, derived
from running the test suite against the Apache Tuscany SCA
runtime.

<!--
Address of the Web service provided by component "TEST_ASM_5032Component2"
in Test_ASM_5032 composite -->

<!ENTITY
ws_addr_5032
"http://localhost:8080/TEST_ASM_5032Component2/Service1/binding2">

<!--
Address of the Web service provided by component "TestComponent2"
in Test_ASM_5034 composite -->

<!ENTITY
ws_addr_5034
"http://localhost:8080/TestComponent2/Service1/second">

This DTD file contains the Entity declarations
for all of the Entity References held in the contribution to which it belongs
- and provides their values.

Note that this file has explicit statements
that it can be modified to contain appropriate values for each of the Entities.
 The provided values are

examples (which happen to work with
the Apache Tuscany SCA runtime).

This proposal affects the artifacts
for testcases ASM_5032 and ASM_5034 and you can see the new versions of
the artifacts in the

OASIS SVN repository.
