Queries4TOSCA Conformance Test Suite 1.0 Release Candidate

This document specifies the conformance test suite for the Queries4TOSCA specification which can be used to evaluate Query4TOSCA implementations. The specification is under active development and is not backwards compatible with any previous versions.

Conformance Tests

Each test is described on a separate page. The description includes typically a service template, a query, expected results and so on along with an explanation about the expected processing.
