Advances in Model-Based Software Testing
15-16 May 2005
http://a-most.argreenhouse.com
There is a need for renewed stress on rigorous and disciplined
approaches to software testing as a result of the growing focus of
product liability on software.
As an industrial reality, an order of magnitude reduction in the
cost of effective testing is needed. Model-based testing
methodologies can provide this discipline and rigor. A premise of
model-based software testing is the creation of models of the
software being tested as opposed to adhoc and manual creation of
test suites. Despite progress in model-based software testing the
practice is limited to relatively few organizations. The goal of
this workshop is to bring together researchers and practitioners to
describe, discuss, and advance the current state of the art AND the
current state of the practice in model-based software testing.
Submissions are solicited that describe new research, tools and
technologies, noticeable industry experience reports, and position
papers which will collectively advance the state-of-art and the
state-of-practice in the area of Model-Based Software Testing.
Topics of interest include, but are not limited to:
MODELS
Black Box (Requirements Based)
White Box (Code Based)
OMG's MDA
Markov Chain
Combinatorial Designs
Systems of Systems
Embedded Systems
PROCESS
Test Generation Algorithms
Test Oracles
Tracing Requirements to Test Cases
Automated Change Management
Testing Tools
Test Management Systems
MEASUREMENT
Estimating Reliability
Coverage Analysis
Risk Assessment

Stevens Institute Research/Thesis Abstracts Available
eValid use at Stevens Institute of Technology under the direction of
Prof. Larry Bernstein, Computer Science Department, has led to the
publication of two MS thesis papers, abstracted and linked below.
Jabu Woodard (December 2004)
This Thesis "Overhead -- Bane of Layered Network Design," examines
the effect of adding an OSI layer of overhead to website protocols,
and uses eValid to measure the relative overhead.
Aketa Parikh (December 2004)
This Thesis, "Trustworthy Software," examines the demand for Secure,
Reliable and Safe (SRS) software systems. These concepts are
illustrated in three "student projects" which are analyzed in part
with eValid to assess their reliability and safety.
Copies of both of these theses can be downloaded from:

Second International Workshop on
Quality Assurance and Testing of Web-Based Applications
in Conjunction with COMPSAC 2005
(URL: http://aquila.nvc.cs.vt.edu/compsac2005)
July 25-28, 2005, Edinburgh, UK
Contact: hzhu@brookes.ac.uk, kung@cse.uta.edu
The Internet is rapidly expanding into all sectors of our society
and becoming an indispensable platform of information systems and
other computer applications as well. Web-based applications are
complex, ever evolving and rapidly updated software systems. Testing
and maintaining web-based applications are a nightmare because the
Internet is a heterogeneous, distributed, multiplatform,
multilingual, multimedia, autonomous, cooperative wide area network
computing environment. Traditional quality models, testing methods
and tools are not adequate for web-based applications because they
do not address problems associated with the new features of web-
based applications. At present, web-based applications testing and
maintenance are still an unexplored area and rely on ad hoc testing
processes. Little has been reported on systematic testing methods
and techniques, quality metrics, and dependability of web-based
applications, to mention just a few.
The first workshop on quality assurance and testing of web-based
applications was successfully held at IEEE 28th Annual International
Computer Software and Applications Conference (COMPSAC'04) in Hong
Kong, Sept. 30, 2004. This is the second workshop of the series. It
is aimed to provide a forum for researchers, practitioners and tools
vendors to exchange ideas, research results, practical experiences
and lessons learned on quality assurance and testing of web-based
applications. It will also be held at COMPSAC'05 in Edinburgh, UK,
July 25-28, 2005.
Testing and Quality Assurance Methods and Techniques
Effective quality assurance and testing of web-based applications
require a systematic approach, which include models, methods and
techniques that deal with the representation of software artefacts
under test and processes for the analysis of these artefacts, and
the generation of test cases/test data from them. This theme seeks
proposals of test models, methods and techniques for web-based
applications including but are not limited to the following:
* Test models and meta-models
* Verification and validation techniques, such
as modelling checking, consistency and
completeness checking, etc.
* Analysis and testing
* Test criteria
* Architecture and framework
* Reverse engineering
* Exception handling
* Testing for security, privacy and trustworthiness
* Content management
* Tools and environments
Process and Management Issues
A process is a sequence of macro-level activities performed to
accomplish a significant task. This theme deals with processes and
management activities for quality assurance and testing of web-based
applications. Example topics are:
* Quality management
* Human factors
* Web configuration management
* Metrics and indicators
* Maintenance and evolution
* Content management
* Process improvement
* Quality of service
* Security and privacy (as quality metrics)
* Dependability
* Fault tolerance and automatic recovery models
Practical Applications and Experience
Reports on quality assurance and testing of practical web-based
applications or industrial experiences are strongly encouraged.
Topics include but are not limited to:
* Quality assurance and testing of E-Commerce applications
* Quality assurance and testing of E-Government applications
* Quality assurance and testing of E-Science applications
* Quality assurance and testing of Wireless applications
* Security and privacy in practice
* Lessons learned
Technology Impact
This theme is concerned with impact of related technologies to
quality assurance and testing of web-based applications as well as
impact of quality assurance and testing of web-based applications to
other technologies. Example technologies are: * Bio-metric
technology * Data warehouse and data mining * Agent technology *
Autonomic computing * Component software engineering * Wireless
communication * Mobile computing * Service-oriented computing *
Ubiquitous/pervasive computing * Network centric computing * Web
services technologies * Grid computing * Open grid service
architectures * Grid middleware

3rd Workshop on Software Quality
http://attend.it.uts.edu.au/icse2005/
International Conference on Software Engineering 2005
http://www.cs.wustl.edu/icse05/Home/index.shtml
17 May, 2005
St Louis, Missouri, USA
Motivation To develop software quickly, on time and within budget is
not good enough if the product developed is full of defects and
today, software stakeholders are demanding higher quality software
than ever before. As the software market matures, users want to be
assured of quality. They no longer accept the claims of the IT
department at face value, but expect demonstrations of quality. In
recent years, much of the software engineering research has focussed
on standards, methodologies and techniques for improving software
quality, measuring software quality and software quality assurance.
Most of this research is focused on an internal view of quality
whereas few measures of the customer view of quality exist.
Co-located with the International Conference on Software Engineering
(ICSE), the premier software engineering conference, this workshop
intends to bring together academic, industrial and commercial
communities interested in software quality in order to discuss the
different technologies that have been defined and used in the
software quality area. The topics of interest in this discussion
span the full range of software quality issues, including the
following:
* Software Product Evaluation and Certification
* Tradeoffs in Quality during software development
* Software Process Definition, Evaluation and Improvement
* Software Quality Education
* Introduction of Software Quality Programs
* Methods and Tools for Quality Assurance
* Quality Metrics
(In-process quality and customer views of quality)
* Software Quality for different domains
(eg agile, web, open source etc)
* Software Quality at different stages of the development lifecycle
* Total Quality Management
* Building quality into software products
* Project management and software quality
* Testing, Inspections, Walkthroughs and Reviews

Fourth International Workshop on
Automated Verification of Infinite-State Systems (AVIS'05)
Co-located with ETAPS 2005
2nd-3rd April, 2005
Edinburgh, Scotland
http://chacs.nrl.navy.mil/projects/AVIS05/
This workshop is a forum for researchers, students, and
practitioners interested in the application of formal methods and
tools for the automatic verification of large practical systems.
Formal methods, in particular model checking, is increasingly being
used in industry to automatically establish the correctness of (and
to find flaws in) finite-state systems, such as descriptions of
hardware and protocols. However, model checking is limited in scope
due to the state explosion problem. Most practical system
descriptions, notably that of software, are therefore not directly
amenable to finite-state verification methods since they have very
large or infinite state spaces. For such systems, theorem proving
-- a process that requires manual effort and mathematical
sophistication to use -- has so far been the only viable
alternative.
More recently, we have seen the emergence of hybrid techniques that
combine the ease-of-use of model checkers with the power of theorem
provers. Tools based on these techniques afford users with full
automation, and are less sensitive to the size of the state space
(which may be infinite or arbitrarily large). There is a growing
body of knowledge in this field which has a very exciting future.
The intention of this workshop is to build a forum for exchanging
ideas and experiences by bringing together theoreticians, tool
builders, as well as practitioners who are interested in this
emerging area of research in formal verification.
The workshop will be co-located with European Joint Conferences on
Theory and Practice of Software 2005 2-10 April 2005, in Edinburgh,
Scotland. The two day workshop will be held on 2nd and 3rd April
2005.

John Musa's "Professor's Corner"
Email: j.musa@ieee.org
Software Reliability Engineering website:
The essential guide to software reliability
http://members.aol.com/JohnDMusa/
The following might perhaps be of interest to you. I often receive
email questions and requests for information on many different
aspects of software
reliability engineering, and I have provided some of this
information on my website. I recently decided to organize this more
carefully. In addition to the information I provide about my
training and consulting services and new book, I have set up five
noncommercial areas of interest to support the general software
reliability engineering community. These are: Orientation, the
Professors' Corner, the Researchers' Corner, the Practitioners'
Corner, and Resources for Everyone. The material includes some
material I prepared myself and carefully selected hyperlinks to high
quality material appearing elsewhere on the Internet. This website
has been in existence for almost 9 years, and I would expect to
maintain it for the foreseeable future.
The Professors' Corner includes a link to software reliability
engineering slides and course materials. The Researchers' Corner
include links to software failure data and an enormous archive of
debugging histories of programs suitable for reliability research.
The Practitioners' Corner includes links to standards and a
continually updated bibliography of published articles on actual
applications of software reliability engineering. Resources for
Everyone includes links to the software reliability estimation
program CASRE, the CASRE Forum, CASRE Support, and ISSRE. There is
also information on the SRE Network and the Technical Committee on
SRE.
Please feel free to use this material as indicated and to encourage
others to use it. Although some of it is copyrighted, in most cases
permission to use is granted as long as it is not sold or
commercially exploited and proper credit is given. Also, please let
me know of the existence of other high quality material of general
interest on software reliability engineering if you think it might
be beneficial to include it or provide hyperlinks to it.

Software Engineering for Secure Systems (SESS05)
Building Trustworthy Applications
http://homes.dico.unimi.it/~monga/sess05.html
May 15-16, 2005
St. Louis, Missouri USA
An ICSE 2005 workshop
http://www.cs.wustl.edu/icse05
Theme and goals
Every software application is built and deployed to accomplish some
goal pursued by its interested parties. Thus, software engineers aim
at designing, implementing, and maintaining valid applications that
meet the needs of stakeholders. However, every application can be
also potentially misused, that is, used to pursue goals that
contrast the ones intended by stakeholders. Therefore, software
engineers should try to design applications that, while still
valid, are also trustworthy and cannot be misused. Validity and
trustworthiness are goals that often cannot be achieved either
because they are too costly or because they stem from conflicting
needs. Historically, the software engineering community has strived
more to obtain validity than trustiness. Nowadays, however, software
ubiquity in the creation of critical infrastructures has risen the
value of trustworthiness and new efforts should be dedicated to
achieve it.
The major source of vulnerability of systems has been recognized to
be poor-quality software. However, while secure applications are
also valid and robust ones, security is a specific non-functional
requirement that has to be explicitly and carefully taken into
account during analysis, implementation, testing, and deployment.
Moreover, some of the most successful techniques used by software
engineers may conflict with security objectives. Abstraction, for
example, is the invaluable device the designers use in order to cope
with complexity, but, since it is rarely applied as a pure
mathematical generalization, it could force one to neglect details
that can be exploited to misuse an application; late binding, while
a fundamental tool in pursuing design for change, could be hijacked
to adapt systems to malicious goals; COTS, commercial off-the-shelf
components, if they might foster the profitableness of software
industry, they also introduce black-box subsystems that are
difficult to manage when reasoning about the chain of trust of the
whole system.
This workshop will provide a venue to discuss techniques that enable
the building and validation of secure applications. We are
especially interested in (1) design and implementation approaches
that make it easier to deal with security requirements, and (2)
program analysis techniques that enhance the trustworthiness of
applications.
Areas of interest include, but are not limited to:
o Security requirements management
o Architecture and design of trustworthy systems
o Architecture and design of protection systems
o Separation of the security concern in complex systems
o Secure programming
o Black box components trustworthiness
o Security testing
o Trustworthiness verification and clearance
o Defining and supporting the process of building secure software
o Deployment of secure applications

Fifth International Workshop
on
Web Based Collaboration (WBC'05)
August 22 - 26, 2005
Copenhagen (Denmark)
http://www.kti.ae.poznan.pl/dexa_wbc2005/.
In the last few years, the applicability and functionality of
systems for collaboration support has expanded, leading to their
growing application in organizational, communication, and
cooperation processes. This provides opportunities to study their
technical, business and social impacts. Usually an integration of
incoming technology with existing organizational practices is very
challenging. The knowledge gained from such experiences is a
valuable resource for all those who plan to develop software tools
to support team interaction.
At the same time we observe a growing influence of World-Wide Web.
WWW - by now the most popular service over the Internet - evolves
rapidly, from a simple, read-only data storage system, as it was a
few years ago, to nowadays universal, distributed platform for
information exchange. New Web-based applications with freely
distributed data, end-users, servers, and clients, operating
worldwide, are central topics of many research activities. Recently
the WWW has also been perceived as an attractive base for a
distributed computer system supporting cooperative work, since the
Internet is the most flexible network with the architecture that
could support group activities to maximum extent.
In parallel to the WWW evolution we observe a growing impact of new
technologies: agent systems, mobile computing, workflow, and
ubiquitous computing. We can expect that these technologies will
also exert a large influence on group/organizational structures and
processes.
All the aforementioned emerging new technologies are exciting in
their own right, but their technological and organizational
integration to support collaboration raises many interesting
questions and is a challenging, new research agenda.
WBC'2005 is a continuation of the previous successful workshops on
Web Based Collaboration, organized in September 2001 in Munich,
Germany, in September 2002 in Aix-en-Provence, France, in September
2003 in Prague, Czech Republic and recently in September 2004 in
Zaragoza, Spain.
WBC'2005 attempts to integrate two themes of practice and research:
the functional, organizational, and behavioral issues and the
modeling or implementation issues associated with collaborative Web
based work. WBC'2005 brings together practitioners and researchers
from different domains working on design, development, management,
and deployment of Web-based systems supporting teamwork within
organizations.
emphasis on their relation to collaboration. The Relevant topics may
include the following (but not limited to):
- Collaborative Systems: strategies of human cooperation over the Web,
computer platforms and architectures in support of remote
cooperation, mediators, wrappers, design and implementation issues
of collaborative applications;
- Agent Technologies: agents supporting cooperation, agents for
finding, collecting and collating data on the Web, brokering agents,
agent-communication languages;
- Software Engineering: modelling languages and tools of collaborative
systems, programming languages concepts and paradigms supporting

collaborative systems, languages for the descriptions of
collaboration, cooperation and coordination between agents;
- Interoperability Infrastructures: compositional software
architectures in support of collaboration, combining distributed
object management platforms with Web and Java for cooperative
applications, middleware infrastructures, describing metadata on the
Web, providing semantic interoperability through metadata, emerging
interoperability standards;
- Dataweb Technology and Database Infrastructure for collaboration:
Web access to databases including Java Database Connectivity,
database Web servers, Web interfaces to databases, database Web
applications;
- Workflow Systems: workflow architectures in support of collaboration
processes, modeling of cooperation processes, truly distributed
enactment services and interoperability of workflow engines, dynamic
modification of running workflows;
- Electronic Business: establishment of contacts, suppliers search and
negotiation, contract negotiations, Business-to-Business and
Business-to-Employee cooperation support, establishment and
coordination of virtual enterprises, shared business processes.
