+# pyswagger unittests for the API & UI
+
+## Requirements
+
+```
+wg-quick up conf/wg-example0.conf
+sudo LOG_LEVEL=debug CONFIG_FILE=conf/config.yml ../dist/wg-portal-amd64 
+
+python3 -m venv ~/venv/apitest
+~/venv/apitest/bin/pip install pyswagger mechanize requests pytest PyYAML
+```
+
+## Running
+
+### API
+```
+~/venv/apitest/bin/python3 -m unittest test_API.TestAPI 
+```
+
+### UI
+```
+~/venv/lsl/bin/pytest pytest_UI.py 
+```
+
+
+## Debugging
+Debugging for requests http request/response is included for the API unittesting.
+To use, adjust the log level for "api" logger to DEBUG
+
+```python
+log.setLevel(logging.DEBUG)
+<action>
+log.setLevel(logging.INFO)
+```
+This will provide:
+```
