-# Run Test Suite
+# Test Suite
 
+The test suite is located within the tests directory and is organized into two subdirectories: unit and selenium. 
+The unit directory contains unit tests, which focus on testing individual components of the project in isolation. 
+The selenium directory contains tests that utilize Selenium for browser-based testing,
+ensuring that the user interface and web interactions function as expected.
 
 ## Run "Unit" tests 
+Unit tests are executed within a Docker container using the pytest framework.
+This ensures a consistent testing environment, isolated from local machine configurations.

+Selenium tests run on the host machine. 
+This is due to the fact that Selenium does not currently support the ARM64 architecture for Linux Docker images.
+This will require some more steps to be taken before running the tests.
+### Prerequisites
+- pdm
+
+### Installation
+1. **Services**
+
+   To run the tests locally, the following services are required:
+
+   1. **Postgres**
+   1. **Redis**
+   1. **Elasticsearch**
+
+   You can either install these services manually or use the `docker-compose` file located in the `development_tools` directory.
+
+1. **Running Services with Docker Compose**
+
+   Make sure you have the required `.env` file from the backend setup, then you can run the services using the following command:
+
+   ```bash
+   cd development_tools
+   docker compose --profile services up
+1. Install system requirements
+   1. MACOS
+      1. `brew install wkhtmltopdf pango postgis gdal`
+1. Crate virtual env
+   1. `pdm venv create`
+1. Register the created venv for the project with 
+   1. `pdm use` 
+1. Activate your venv 
+   1. `eval $(pdm venv activate)`
+1. Check your environment
+   1. eg. $`python --version` -> see that it uses Python 3.11.*
+1. Install the packages
+   1. `pdm sync --no-editable --no-self --no-isolation`
+1. Run the tests
+   1. `source ./development_tools/local_selenium_init.sh`
+   1. `python -m pytest -svvv ./tests/selenium --html-report=./report/report.html`
