Conception and modular architecture of ECU-TEST allow straightforward customization, extension, and integration in existing validation and test processes. The existing client/server-solution allows direct communication with interfaces and software tools at multiple test bench computers in a test environment network. ECU-TEST already supports numerous test environment hardware and software. Adding further interfaces, if required, can be done easily. In order to integrate with test management systems such as Mercury Quality Center, ECU-TEST offers a COM interface.
