# libvirt TCK : Technology Compatibility Kit

The libvirt TCK provides a framework for performing testing of the integration between libvirt drivers, the underlying virt hypervisor technology, related operating system services and system configuration. The idea (and name) is motivated by the Java TCK.

In particular the libvirt TCK is intended to address the following scenarios:

- Validate that a new libvirt driver is in compliance with the (possibly undocumented!) driver API semantics
- Validate that an update to an existing driver does not change the API semantics in a non-compliant manner
- Validate that a new hypervisor release is still providing compatibility with the corresponding libvirt driver usage
- Validate that an OS distro deployment consisting of a hypervisor and libvirt release is configured correctly

Thus the libvirt TCK will allow developers, administrators and users to determine the level of compatibility of their platform, and evaluate whether it will meet their needs, and get awareness of any regressions that may have occurred since a previous test run.

For more details you can look at:

- The initial mail from Daniel Berrange presenting the project.
- The page describing VirtTCK the inclusion of libvirt-TCK as a Fedora Feature.

Libvirt-TCK is maintained using a GIT repository, and comment, patches and reviews are carried on the libvir-list development list.
