The core of OpenTAP is a cross-platform and open source test sequencer for hardware and software test automation with a modular architecture of plug-ins supported by an infrastructure and a growing community.


Plug-ins for test steps, instruments and other hardware, DUT's are developed in C# (or Python) using for example Visual Studio. Existing C# test code can usually be converted to the test step plug-in structure.


OpenTAP is released under MPLv2 copyleft licensing allowing full control over your intellectual property.


Keysight provides a development tool, PathWave Test Automation (more info here), for development and debugging of test plans.

GJC Test & Software, as a Keysight Solutions Partner, sells PathWave Test Automation licenses.


In addition, GJC Test & Software offers a flexible and customizable test executive, OTE (more info here), based on OpenTAP for use in production and deployed systems.
