Test Definition Project

The Test Definition Project is consists of work to categorize and harmonize the attribute of open source tests, so that tests and test artifacts can more easily be shared between different test projects.

Tim Bird is working on a "Test Definition Standards" document, to be presented and discussed at various meetings in the Fall of 2019.

This page has information that is being retained on this wiki as resources for this work.
