+# Clear Test Suite
+
+This repository contains integration and verification tests for the `clear` desktop environment programs, specifically:
+- `clear-river` (Wayland compositor with background blur support)
+- `clearwm` (window manager / layout agent)
+- `clear-ui` (WebGPU-based desktop widget system)
+
+The tests run in a **headless Wayland session** using the `headless` backend of `wlroots` to ensure portability and automated execution.
+
+## Features tested
+1. **Window Opacity**: Verifies that client windows (such as `clear-ui`) render with expected transparency/alpha settings.
+2. **Background Blur**: Confirms the compositor's background blur is successfully initialized and enabled for mapped window surface trees.
+3. **Window Layout and Tiling**: Verifies that IPC commands sent via `clearctl` dynamically update tiling layouts (Cascade, Grid, Vsplit, etc.) and window geometries as expected.
+
+## Requirements
+- Python 3.x
+- `Pillow` (for screenshot color analysis)
+- `grim` (for Wayland screenshot capture)
+- `clear-river` and `clearwm` built/installed
+
+## Running the Suite
+
+You can execute the whole test suite using the orchestration script:
+```bash
+python3 run_suite.py
+```
+
+Or run individual tests with python unit tests or pytest if desired:
+```bash
+python3 -m unittest discover tests
+```
