Submitted by: Gebhard Dunst Test Engineer Porsche Informatik, Austria I once discovered a bug in our large windows NT application. The bug was in a new version and it caused it to crash every ten to twenty minutes or so. As the senior tester, I informed the project manager about it, but he denied the problem, saying that nothing critical had been changed for the version and that the crashes had to be due to my system settings. The "buggy" version went out to the customer and the next day we played havoc: The application crashed every two minutes. We recalled the application and set the customer back to the previous version. Knowing about the bug, I spent two days in trying to replicate it: it appeared over and over again, but I couldn't say exactly when. Needless to say, that this made it impossible to fix the bug. I seemed to get fewer crashes with different system configurations and this led us to a bitter task: We set up exactly the same configuration as the customer had on my client PC: including "ini" files, the clients 200 MB original database and anything else. I started to test the different configurations, checked every change in every "ini" file from this version to the last. I set up different databases and spent hours of testing. Sometimes the app crashed immediately, sometimes I could work for about an hour without failure. I got to replicate the error and -- you guess it -- it was all too simple. It surfaced when closing several windows with the ESC key. The bug fix included moving one line of code to a different location... I guess that looking for such a mysterious bug is a highlight in testing rather than a nightmare. Never have I seen half the development team surrounding my pc, watching in interest and discussing what was happening. Editors Note: $50 to Mr. Dunst for this nightmare! ======================================================================== YOUR WORST TESTING NIGHTMARE: THE CONTEST! We know there must be a million nightmarish stories about "what happened to me when I tried to test..." out there.

The Tenth International Software Quality Week Conference and Vendor Exhibition was held in San Francisco from May 26 to May 30, 1997. It was a gala affair and dealt with issues facing today's software developers and testers in a meaningful way. The conference papers were well presented, the proceedings are quite good and there was energy not felt at too many recent conferences. A Birds-of-the-feather session addressed "Trustworthy Software" and here are some findings: 1. People could not agree on what 'Trustworthy" meant; yet there was a consensus of 125 people that something was needed. The notion that the customer or supplier could declare a system "Trustworthy" if they followed some defined process was agreed to. 2. Dick Hamlet of Portland State University made the point that software "best practices are often not known and when they are they are not practiced." 3. He pointed out that the best processes deal with investment in tooling and technology before setting up administrative processes to encourage people to work harder. 4. (Lori Clarke pointed out that "process without underlying technology is bureaucracy," at a UMASS conference last year.) 5. Avoiding Data Corruption is fundamental to trustworthy software. 6. The software industry needs to agree on business practices for: a. Recalls b. "Stop Ship" orders c. Defining boundary conditions d. Specifying behavior at the boundary conditions. e. Conformance to standards f. Defining software life expectancy. 7. A consensus was reached on a set of ethics for internal and external software suppliers for trustworthy systems: a. A software architect would be named and sign off that the software product was fit for use. b. A software project manager would be named and sign off that the software was fit for use. The architect and the project manager could be the same person. c. Fitness for use means that: 1. the software works, 2. it solves the problem, 3. a formal documented process was used in its development, 4. the software is not harmful and 5. risks are documented and managed. 8. It was suggested that the Food and Drug Administration procedure for assuring the safety of software become an industry wide standard. 9. It surprised me that no mention was made of IEEE, ACM or other professional society efforts to establish a set of ethics was mentioned. ======================================================================== Software Research Announces Comprehensive Cooperative Marketing Agreement with Aonix. San Francisco, CA, May 16, 1997 -- Aonix and Software Research, Inc. (SR) have announced a comprehensive sales and marketing agreement which offers the first end-to-end solution of Automated Software Testing Tools available in one package today. Through the integration of their complementary tools, the two companies provide a process for reducing the error-prone nature of testing -- an area where software developers spend most of their time. In the past test cases were generated by hand. The Aonix test tool generates test cases automatically at ten times the rate of manual methods. The Aonix automatic test case generation coupled with Software Research/TestWorks for automatic test execution will dramatically improve productivity of software testing by decreasing test schedules. The two tools together will also increase quality of software testing through increased test coverage. The agreement between the two companies includes exclusive use by Aonix of Software Research's TestWorks suite in all Aonix sales/installations, special emphasis by Aonix and Software Research/TestWorks on sales of the 10X program, and sharing of sales distribution and leads by both organizations. The 10X program offering, which includes five days of comprehensive training on Requirements Modeling and Specification Based Testing works in the following way: Starting with Aonix' Software through Pictures StP/OMT product with the Use Case Editor, the user records requirements and uses "T" the Aonix test case generation tool for generating test cases. Then the users runs Software Research's TestWorks Regression suite for automated test execution, validation and test management of the generated test cases. Once it has been determined that the test cases demonstrate the requirements, Software Research's SR/TestWorks Coverage tool evaluates the quality and completeness of the test cases by indicating how much of the source code has been exercised at the branch, call-pair and path or path class level. All information is easily accessible through visual reports. SR/TestWorks Tool Suite The SR/TestWorks tool suite offers a family of integrated testing and QA products for test data generation, regression testing, capture and playback, test execution and evaluation. SR/TestWorks also provides software test management and reporting, code comprehension, coverage analysis, metrics and maintenance in some of the most-commonly used languages such as Java, C, C++, Ada and Fortran F77. TestWorks is available for the major UNIX platforms, Windows 95, Windows NT and DOS. Its open architecture allows for testing of enterprise-wide applications in both embedded or client/server systems and GUI desktop or Web applications. The Aonix Tool Suite The Aonix tool suite includes: Software through Pictures Object Modeling Technique (StP/OMT), a robust multi-user analysis and design environment with a shared repository that supports development teams through the full life cycle of object-oriented application development; the Use Case Editor which performs high level analysis with usage models to identify requirements; and the "T" Test Case Generator which automatically builds test cases to test the validity of those requirements. Dr. Edward Miller, President of SR said, "The reasons to thoroughly test software are even more true than they have been historically, and the opportunity now exists to assure quality from the very beginning of the software life cycle, when the chance to prevent defects has the highest payoff, to the end of the development cycle, where very often the most critical defects that affect product quality are often found." "The agreement we've signed is historic because it provides a true end- to-end solution to the software development process that is affordable, efficient, effective and more comprehensive than any other available solution." "The Aonix and SR suite of tools is the most complete set of testing tools on the market providing and end-to-end testing solution to the user with tools for creating test-ready specifications and models, tools for generating test cases and scripts, tools for managing large sets of test cases and scripts, tools for executing test scripts, and tools for evaluating test coverage," says Bob Poston - Director of Testing Tools & Practices for Aonix and author of the book "Automating Specification- Based Software Testing" About Software Research, Inc.

Leavens, Iowa State University, USA Robyn Lutz, Iowa State University and NASA Jet Propulsion Laboratory, USA Helen Gill, Defense Advanced Research Projects Agency, USA Oscar Nierstrasz, University of Berne, Switzerland Murali Sitaraman, West Virginia University, USA Bruce W. Weide, The Ohio State University, USA Description The objective of this workshop is to explore how formal (mathematical) techniques can be or should be used to establish a suitable foundation for component-based software engineering. We would like to bring together: * researchers and practitioners in component-based software engineering who are interested in better theoretical foundations, and * researchers and practitioners in formal methods who are interested in bridging the gap between principles and practice The idea would be to help make research in both areas more productive. For example, researchers in formal methods have only recently begun to study: * object-oriented design, specification, verification, and * architectural issues for component-based systems, but other issues are also important in the practice of component-based systems, such as: * parameterization and inheritance, * performance (time and space), * reuse, * software composition, * reducing evolution and maintenance costs. The participants will brainstorm about these and related problems to understand both the problems and how formal techniques may be useful in the solving them. The main expected result of the meeting will be: * an outline of collaborative research topics * a list of areas for further exploration. Details may vary with the background and interest of the participants. Submissions Invitation to the workshop will be based on accepted position papers. An ideal position paper would identify new research topics, areas, or problems related to component-based software engineering. Position papers should address the following questions. * What is the problem (or topic or area) that is being described? * What is the significance of the problem for component-based software engineering? * What theoretical or practical insights might help to solve this problem? * What related work is there about the problem and the theoretical approach? How does it compare? Position papers must follow the format given in the file http://www.cs.wvu.edu/~resolve/FoCBS/FoCBS.tex Submissions are due by July 15, 1997 and must not exceed 10 pages. Four hard copies must be sent to: Gary T. Leavens Department of Computer Science Iowa State University 226 Atanasoff Hall Ames, Iowa 50011-1040 USA Tel: (515) 294-1580 Fax: (515) 294-0258 leavens@cs.iastate.edu See http://www.cs.wvu.edu/~resolve/FoCBS/ for more details. ======================================================================== Second BCS-FACS Northern Formal Methods Workshop Call for Participation Craiglands Hotel ILKLEY, UK, 14-15 July 1997 The aim of the BCS-FACS Northern Formal Methods Workshop is to foster research and collaboration in formal methods by bringing leading figures and young researchers together in a friendly and informal atmosphere, in which participants can exchange and contribute novel ideas and innovative developments.
