(Phys.org) —BugBuster: one bot can test almost every function on a website. This tiny revolution for web developers means great gains in time and reliability.
To overcome problems that come with using websites, which can be annoying and bring extensive financial consequences for large companies, the start-up BugBuster has invented the first intelligent tool that finds out on its own how to interact with an application whose code it tests according to various possible scenarios. It notes the problems to designers as screen captures. The robot, currently available in beta form, will save a lot of time for designers and provides increased reliability. In the next few days, two of the designers of this technology from the Operating Systems Laboratory of EPFL, Olivier Crameri and Renault John-Lecoultre, will present their system in the United States during two major conferences for specialists.
Simply enter the URL onto the company's website and press "start." The automatic and intelligent explorer analyzes the source code and guesses where to click and what values to enter in order to maximize code coverage. It then identifies the bugs on screen captures and provides detailed information on debugging.
And when the system reports an error—that is precisely what it is. "False positives are not possible. This level of reliability brings a considerable savings of time," said Olivier Crameri. The system works on a subscription basis for a particular website and can also test mobile applications. It supports all HTML5 applications. Distributed via the "cloud" it will be commercially released in a few months.
Until now, no test has existed that can validate, for example, all the possibilities when it comes to an application in which user interaction is required, as with filling out a form. The strategy is to schedule the test scenarios, which are long and tedious to write, considering that the user clicks here and there… and then to automatically replay each change. Via the integration of a few simple lines of code, the new bug hunter can solve this problem and systematically test all possibilities.
