+
+## Debugging
+
+The contract testing system is optimized to run within a set of related docker images.
+

+See the `Debugging` section of the client [README][client_readme] 
+
+### Contile
+
+To run the contile service, and it's dependant partner service locally, execute the 
+following from the contract-tests root:
+
+```shell
+docker-compose run -p 8000:8000 contile
+```
+
+Contile runs, by default, on `http://localhost:8000/`.
+However, it may be necessary to run the tests outside of docker, in order to debug 
+functions or manually verify expected results.
+
+**Fetching Tiles**
+
+Contile will attempt to look up your IP address if you access it using Firefox. 
+The easiest way to get a test response back would be to craft a curl request. 
+For example (presuming that Contile is running on `http://localhost:8000/v1/tiles`):
+
+```sh
+curl -v \
+    -H "User-Agent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:10.0) Gecko/20100101 Firefox/91.0'" \
+    -H "X-Forwarded-For: '89.160.20.115'" \

+## Debugging
+
+To execute the test scenarios outside the client Docker container, expose the Contile 
+and partner API ports in the docker-compose.yml, set environment variables and use a 
+pytest command. It is recommended to execute the tests within a Python virtual 
+environment to prevent dependency cross contamination.
+
+### Environment Setup
+
+Install all requirements via [pip-tools][pip-tools]:
+
+```shell
+pip-sync requirements.txt dev-requirements.txt
+```
+
+With requirements installed run the code checks and test via [tox][tox]:
+
+```shell
+tox
+```
+
+See the tox configuration in the `tox.ini` for the list of environments this
+will run.
+
+### Execution
+
+1. Modify `test-engineering/contract-tests/docker-compose.yml`
+
+    In the partner definition, expose port 5000 by adding the following:
+    ```yaml
+    ports:
+      - "5000:5000"
+    ```
+
+    In the Contile definition, expose port 8000 by adding the following:
+    ```yaml
+    ports:
+      - "8000:8000"
+    ```
+
+2. Run Contile and partner docker containers.
+
+   Execute the following from the project root:
+   ```shell
+   docker compose -f test-engineering/contract-tests/docker-compose.yml up contile
+   ```
+
+3. Run the contract tests
+
+    Execute the following from the project root:
+    ```shell
+    CONTILE_URL=http://localhost:8000 \
+        PARTNER_URL=http://localhost:5000 \
+        SCENARIOS_FILE=test-engineering/contract-tests/volumes/client/scenarios.yml \
+        pytest test-engineering/contract-tests/client/tests/test_contile.py --vv
+    ```
+    * Environment variables can alternatively be set in a pytest.ini file or through an 
+      IDE configuration
+    * Tests can be run individually using [-k _expr_][pytest-k]. 
+      
+      Example executing the `success_desktop_windows` scenario:
+      ```shell
+      pytest test-engineering/contract-tests/client/tests/test_contile.py \
+          -k success_desktop_windows

+## Debugging
+
+It is possible to run the mock partner app outside of docker. It is ___STRONGLY___ 
+suggested to run this within its own Python virtualenv, and possibly its own 
+shell to prevent environment variable cross contamination.
+
+### Environment Setup
+
+Install all requirements via [pip-tools][pip-tools]:
+
+```shell
+pip-sync requirements.txt dev-requirements.txt
+```
+
+With requirements installed run the code checks and test via [tox][tox]:
+
+```shell
+tox
+```
+
+See the tox configuration in the `tox.ini` for the list of environments this
+will run.
+
+The `services: partner` block of `contract-tests/docker-compose.yml` lists the 
+`environment` and `volumes` needed. The following environment variables are used by 
+the mock partner app.
+
+* PORT - _default port number_
+* RESPONSES_DIR - _directory to read the [Tile Values](#tile_values)_
+* ACCEPTED_MOBILE_FORM_FACTORS - _list of allowed `form-factors` for `tilesp/mobile` responses_
+* ACCEPTED_DESKTOP_FORM_FACTORS - _list of allowed `form-factors` for `tilesp/desktop` responses_
+
+### Execution
+
+Start the mock partner app from inside the mock partner virtualenv using
+
+```sh
+gunicorn -c config/gunicorn_conf.py --preload -k uvicorn.workers.UvicornWorker main:app
+````
+
+**Contile Configuring**
+
+Use the following environment variables for Contile to contact the mock partner server:
+
+```sh
+CONTILE_MAXMINDDB_LOC=${ProjectRoot}/mmdb/GeoLite2-City-Test.mmdb
+CONTILE_ADM_ENDPOINT_URL=http://localhost:5000/tilesp/desktop
+CONTILE_ADM_MOBILE_ENDPOINT_URL=http://localhost:5000/tilesp/mobile
+CONTILE_ADM_QUERY_TILE_COUNT=5
+CONTILE_ADM_SUB1=sub1_test
+CONTILE_ADM_PARTNER_ID=partner_id_test
+CONTILE_ADM_HAS_LEGACY_IMAGE='["Example ORG", "Example COM"]'
+```
+
+`CONTILE_ADM_TIMEOUT` determines how long to wait for a response from the partner server. 
+The default value is `5` seconds. You may wish to make this much longer if you're debugging.
+
+These would be in addition to any other settings you wish to use for the Contile server.
+
+**<a name="tile_values"></a>Tile Values**
+
+The returned tile values are stored in 
+`contract-tests/volumes/partner/${country-code}/${region-code}.yml`.
+
+If different values are desired, you can either alter these files or you can copy them 
+into a new directory and use the `RESPONSES_DIR` environment variable for the 
+mock partner app.
