+# Testing Instructions
+
+This document provides instructions on how to run the automated tests for the Azure Maps MCP server.
+
+## Prerequisites
+
+Ensure you have a valid Azure Maps API Key. The tests expect this key to be present in a file named `.apikey` in the root of the project.
+
+## Setup
+
+1.  **Install Test Dependencies**:
+    It is recommended to run tests in a virtual environment.
+
+    ```bash
+    pip install -r requirements-test.txt
+    ```
+    
+    Ensure `requirements.txt` dependencies are also installed if they haven't been already:
+    ```bash
+    pip install -r requirements.txt
+    ```
+
+## Running Tests
+
+To run the tests, use `pytest`:
+
+```bash
+pytest test_azure_maps_mcp.py
+```
+
+### Options
+
+-   **Verbose output**:
+    ```bash
+    pytest -v test_azure_maps_mcp.py
+    ```
+
+-   **Show print output**:
+    ```bash
+    pytest -s test_azure_maps_mcp.py
+    ```
+
+## Test Coverage
+
+The tests cover:
+-   **Basic Map Retrieval**: Verifies fetching a map image using center coordinates and zoom level.
+-   **Map with Pushpins**: Verifies fetching a map that includes pushpins.
+-   **Error Handling**: Verifies that invalid inputs (e.g., malformed center coordinates) are handled gracefully and return appropriate error messages.

+            # A safe bet: if mapLayer == 'Traffic', we ignore imagerySet or warn.
