Paris-based client-server software engineering specialist Nat Systemes SA reported that its 1993 more than doubled, increasing 103% to approximately $10.5m, with a net profit of some $600,000, compared with $500,000 in 1992. The company says $1.3m of its revenue was generated by its five international subsidiaries, in the US, UK, Benelux, Spain and Italy. In 1994, the company expects to do about $17m in revenues, of which 30% will come from international sales. The encouraging financial results follow on the heels of Nat Systemes’ presentation of NS-Robot, a tool for automating the testing of graphic client-server applications. The tool can be used to test OS/2 or Windows applications developed with either Nat Systemes’ NS-DK software engineering tool or other environments. When applications respect OS/2 or Windows, NS-Robot works perfectly, says Roland Zephir, NS-Robot product manager. From the application interface, the NS-Robot automated capture functions in either record/play back mode or script mode. The logical command scripts can be reused as they were written or enriched with NS-DK functionalities (management of test procedure, cases and data, simulation of application connections) and integrated into complex test sessions that correspond to stages of qualification defined by a quality assurance plan. In a graphical client-server environment, testing procedures are even more important than in a classic centralised environment, since the interdependence between applications and parts of applications is exponential. Only an automated testing tool like NS-Robot can reproduce with certainty the same test conditions. Furthermore, NS-Robot improves application development and maintenance teams, as test resources can be divided among different development and application qualification managers, Zephir says. Initially available under OS/2 and Windows, NS-Robot sells for about $3,450.
