Subject: Re: [regrep] 7/29/2003: Conformance Efforts and ebXML IIC
Please see my comments below. Thanks, Mike ----- Original Message ----- > > Mike, > > The updated format looks very good. A few questions follow: > > -What does the Requirement Level column mean? Is it saying whether the > assertion is part of a required feature or an optional feature? [MIKE] - Yes, Requirement level refers to the specifications use of the MUST, SHOULD, MAY keywords. and equates them with REQUIRED, RECOMMENDED and OPTIONAL. This is important at test reporting time, becase an implementation should not test against a particular requirement if it has not implemented that feature. > If so maybe a more obvious column header is desirable (e.g. "Require Feature" > with value true/false). [MIKE] - You are correct, in that a "true/false" would be more correct ( since RECOMMENDED is still "optional" ), however using RECOMMENDED offers a finer level of detail at test reporting time regarding an implementation's test result against a requirement. In our testing framework, our conformance test driver recognizes RECOMMENDED and OPTIONAL as equivalent and "false". > > -What process, responsible parties, milestones and deliverables do you > you forsee going forward? > [MIKE] - I see an ebXML RS conformance test suite specification document, which contains a list of conformance test requirements ( like the example table we've been discussing ),a conformance test suite ( an XML document, with test cases that validate to the ebXML Test Suite schema as defined in the IIC Test Framework Specification document). Also included in the conformance test suite specification is supporting test material ( XML files that that will be used in LifeCycleManager and QueryManager transactions, like those put together by Len Gallagher in the initial ebRS conformance test suite ). > -Is the end product an "ebXML Registry Conformance Test Specification > (CTS)" document? [MIKE] - Yes. > > -Who produces the initial set of assertions that would be the basis for > the CTS? > [MIKE] - Because of IIC limited resources, we'd like each TC to contribute toward the collection of test assertions. The IIC could guide and contribute, but collection can be a tedious process. I would suggest a "staged" approach, in which test assertions are compiled for a selected "profile" or "level" ( even though the RS specification does not define them ). Spending a year compiling assertions would not necessarily serve the ebXML community, whereas building upon a "core" set of asssertions over time would. > -Who produces the final CTS? [MIKE] - That would be the responsibility of the IIC. > > -Who produces automated test suite for verifying Conformance? > The IIC is normally tasked with this effort. Although again, due to our own resource limitations, we would ask for help from the registry TC in contributing tests to the suite. > -What are/should be some realistic milestones for various deliverables? > [MIKE] - Based upon our own experience in compiling about 200 conformance test assertions for ebMS, this can be a time-consuming task. However, if you take a "divide and conquer" approach to RS testing, you may be able to make this easier. For instance, choosing a single binding (e.g. SOAP) to write test requirements, selecting LifeCycleManager functionality as a higher priority for test requirements than QueryManager functionality... could get the ball rollling sooner. Also, focusing on special areas of concern regarding the RS specification clarification can also reap benefits sooner. Also, setting aside testing requirement that may not yet exist in any implementation can allow focus on actual real-world issues. I started "marking up" the ebRS 2.5 specification, pages 1-40, ( sectoins #1 - #6) just to begin to get a feel for what it would take to "highlight" the specification and identify conformance test requirements. I found that portion of the specification to be straightforward regarding identifying conformance test requirements. The LifeCycleManager section (section #7) appears to be straight-forward and easy to identify testing requirements, grouped into fundamental sub-categores of "parameter", "response", "exception" and "audit trail" types of testing The QueryManager (section #8) could be a very rigorous exercise in test requirement annotation, specifically since each "node" in a FilterQuery tree could be a candidate for testing... I would suggest a "generalized" approach to FilterQuery or SQLQuery testing, in which "duplicate" query tree node testing is eliminated to simplify both test requirement writing, as well as actual test generation. Section #9, Content Management Services, is an optional service, that can be tested by creating/testing an IIC defined content management service to the registry, then verifying its conformant functionality. This could be done by creation and publishing of a "dummy" validation service, I believe. Because this is an optional feature, test requirements for this service could be described.. but actual implementation of test cases "could" be deferred if time/resources are an issue. Section #10, Event Notification Service, is also an optional service, that is well documented and fairly simple to generate test requirements. Acutal test case scenarios should be easy to construct. Again, because this is an optional feature, it is a candidate for test requirement generation, but actual test cases COULD be deferred for a later time. Section #11, Cooperating Registries Support is a complex scenario requiring federated registries for conformance testing. The requirements are well stated, but implementation of test cases will be complex and time-intensive. The specification does not eplicitly say whether this is an optional feature, although I assume that it is. Section #12, Security an be a large exercise, particularly with all of the possible XMLDSIG options. But this is a "required" feature, and can perhaps be described with a small initial set of test assertions and test cases, and a limited testing scope. So from a deliverables standpoint, if you are doing the entire ebRS specification I would suggest ( working in parallel if resources are available ) : 1) "Marking up" the ebRS document to identify testing requirements - 4 weeks 2) "Prioritizing" which marked-up sections of the specification you wish to write conformance test requirements for - done in parallel with the "mark-up" 3) Create a "minimal" ebRS Conformance Test Requirements table ( using syntax described in our example ) - 2 months ( possible if you omit/minimize writing some requirements, such as rigorous FilterQuery/SQLQuery test requirements, Content Management Service, Event Notification Service and Federated Registry test requirements ) 4) To create a "full blown" conformance ebRS Test Requirements Document - 6 months 5) To create a "minimal" ebRS Conformance Test Suite 4 months 6) To create a "full blown" ebRS Conformance Test Suite 12 months 7) To create a Conformance Test Suite Specification - (integrating test requirements, test cases and supporting documentation) - 1 month This is my estimate, based upon IIC work with ebXML Messaging Services. Currently, I am the only person working on test cases for ebMS in the IIC. Others in the TC are editors and reviewers of our documents. This is not likely to change, as others do not have the time to dedicate toward such an intensive task. So I can assist the regrep TC in developoing test requirements and test cases, but it will take assistance to speed up the process. In the IIC, we are currently finishing up the Conformance Test Suite Specification document for ebMS, and will have a final version posted on the OASIS IIC web site within a month. Currently, version 0.9 of the ebMS Conformance Test Suite, along with the ebXML Test Framework document are avaiable at: http://www.oasis-open.org/committees/documents.php?wg_abbrev=ebxml-iic Test cases developed by the IIC are being incorporated by Drake Certivo in their e-business conformance testing tool. Also, the K-WareSoft of Korea has incorporated our test cases into their ebXML MS conformance testing tool. I believe that tests generated for ebRS would fit well with test cases already developed by NIST and used in the open source registry project. I will be finished with ebXML Messaging Services Conformance Test Suite by the end of September. That will be a good time for me to work closer with theregrep TC in developing test requirements and test cases. However, work can certainly begin before the ( for example, annotating the ebRS specification, and beginning a "cut/paste" operation to populate the Conformance Test Requirements Table we've been discussing. Also, the IIC TC must vote upon which specifications it will work with. BPSS is also a hot item for testing now, so the IIC has to prioritize its resources. However, working in "parallel" may be possible.
