However, so far there are no methods to test them systematically and at low cost for malfunctions and security vulnerabilities. Therefore, computer scientists from Saarland University are working on automatic methods of testing, which check complex web applications autonomously. For the first time, they will present this work at exhibition booth F34 in hall 26 at the computer fair Cebit. The trade show will take place from March 6 to 10 in Hannover.
“Ineffective and inefficient” is Valentin Dallmeier’s assessment of the methods that web developers and responsible project leaders rely on to try to find programming errors and security holes in web applications. Dallmeier is a postdoc working at the software engineering chair of Saarland University. Its main focus is systematic automated debugging. The developed methods are functioning very well with typical computer programs. Dallmeier and his colleague Martin Burger have built on that basis, and aim to develop a software system that will determine automatically why Web 2.0 applications fail.
“This is still done manually and therefore causes not only very high costs, but also high levels of risk for companies and the community,” Burger explains. He refers to an article from last December, which revealed that incorrect programming of the “Facebook” social network made it possible to access saved, private photos of members.
Dallmeier and Burger want to prevent such worst-case scenarios and other breakdowns through their software “Webmate.” Businesses and their responsible web administrators will only have to type in their Web address. Afterwards the system will automatically discover how the different components of the application are connected to each other and via which menus, buttons, and other control panels the users are interacting with the application.
Subsequently, it will generate and carry out test scenarios. If it discovers, for example, that the application is not compatible with a certain version of a browser, or a control panel no longer exists in a new version of the application, the system will inform the developer immediately — likewise if a database is not connected, a server does not respond, or a link is dead. The web developer should be able to repeat this test at any time.
In the future, the service will be offered to companies for a fee. The researchers want to promote the technology through their own business, and hope to receive a patent. They will found their own company within the next few months. Dallmeier, the leader of the project, is confident that it is possible to implement the software system soon. “We have done the basic work over the last three years, and we even did some feasibility studies,” he says. He estimates the market potential in Germany alone to be 120 million Euros annually.For further information please contact:

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
