I’m pleased to announce the release of CQL Tests UI, a web application for viewing and analyzing Clinical Quality Language (CQL) engine test results generated by the CQL Tests Runner. I’ve contributed CQL Tests UI to the cqframework family of tools under the Apache 2.0 license following debut at the September, 2025 HL7 Connectathon.
What is CQL Tests UI?
CQL Tests UI is an intuitive web application that provides an interface for visualizing the results of CQL engine compliance tests. Whether you’re working on clinical decision support rules, quality measures, or other CQL-based artifacts, this tool helps you quickly identify engine issues and compare results across different CQL execution implementation environments.
Key Features
Cross-Engine Comparison Dashboard
The dashboard provides a high-level dashboard summarizing test results across engines, allowing for broad-stroke summarization of correct CQL engine functionality across systems.
Detailed Result Viewer
The results detail viewer zooms in on a specific test run. This feature allows you to examine expected and actual output of individual test cases and understand failures.
Flexible Data Loading
The application supports multiple ways to load your test data, making it easy to integrate into existing workflows.
Documentation and Deep-Linking
Built-in documentation and deep-linking support make it easy to share specific test results and collaborate with team members.
