# 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.

# For Azure Maps static image, 'layer' param handles background.
# Traffic flow is often an overlay.
# Checking docs: 'layer' can only be basic, hybrid, labels, terra.
# Traffic flow is not a standard layer option in the static image API v2.
# However, looking at common usage, sometimes 'traffic' is a boolean or separate layer.
# Wait, per Azure Maps Get Static Map API docs:
# To add traffic, often one uses 'layer=traffic'. But the docs say valid values are:
# basic, hybrid, labels, terra, traffic.
# Let's try setting layer to 'traffic' if the user requested it?
# Actually, standard way is often just 'layer=basic' (background) + an overlay?
# Re-reading docs (virtual):
# 'layer' parameter values: 'basic', 'hybrid', 'labels', 'terra', 'traffic'.
# So if mapLayer is Traffic, we should probably override the layer or see if we can combine.
# But the 'imagerySet' determines the base.
# If the user wants Aerial + Traffic, does Azure support that in one call?
# Often 'layer=traffic' means 'basic + traffic'.
# Let's assume if mapLayer=Traffic, we force layer='traffic' (which is usually vector traffic tiles).
pass # Pending verification, but let's implement a simple logic:
# If mapLayer is Traffic, we append it to the layer list or switch mode.
# NOTE: Azure Maps Static Image API allows 'layer=basic,traffic'? No, it takes a single value.
# But wait, looking at some examples, 'layer=traffic' yields a traffic map.
# Let's allow overriding the layer if Traffic is requested.
# However, this might conflict with 'imagerySet'.
# A safe bet: if mapLayer == 'Traffic', we ignore imagerySet or warn.
# Actually, let's look at the docs implied by existing code...
# The existing code didn't use it.
# Let's check if we can pass it as an additional parameter.
# Actually, looking at the code again, let's keep it simple.
# If mapLayer is 'Traffic', we will assume the user wants the traffic layer.
# We will override the 'layer' variable.

# Azure Maps Static Image API (Render V2) uses 'layer' parameter.
