CRATOS is the reference OpenSync testbed and is used by OpenSync developers and testers to develop or test the OpenSync stack on their device. Main benefits using CRATOS are:

  • CRATOS forms a standardized test environment for all OpenSync-enabled devices. The testbed guarantees repeatable and comparable automated and manual test case results (FUT or E2E).

  • CRATOS streamlines the implementation and execution of automated testing.

  • CRATOS enables test or development environment scaling.

  • CRATOS allows you to separate the development/test environment from the rest of your lab/corporate network.

Support

CRATOS users are required to take full ownership of assembling an CRATOS. Public facing CRATOS is not supported today.

OpenSync Certified partners can request a preassembled CRATOS called “OpenSync Reference Testbed (OSRT)” by using the following form. Request a Preassembled OSRT-OpenSync reference testbed. Learn more about Certified partners in Get Certified .
