 - Postal code functions
 - Ip address functions
 - Street address functions (This will call Heremaps or Google so it will cost you 2 credits)
+- Routing functions
+- Isolines functions
+- Data Observatory functions
+
+
+### How to debug the tests
+You won't be able to plug a debugger when using the `run_test.py` because of the usage of a subprocess and the piping.
+
+You should be aware that some tests require some extra setup (a test table), that you'll need to do on your own in some cases (check the `ImportHelper.import_test_dataset`)
+
+In order to do so, you need to use plain `nosetests` which comes prepared to that.
+
+First, add this to the python test code:
+
+```python
+from nose.tools import set_trace; set_trace()
+```
+
+Secondly, execute just your test with this:
+
+```ssh
+GEOCODER_API_TEST_USERNAME=your_username \
+GEOCODER_API_TEST_API_KEY=your_api_key \
+GEOCODER_API_TEST_TABLE_NAME=your_test_table \
+GEOCODER_API_TEST_HOST=your_target_test_host \
+nosetests --where=integration/ test_data_observatory_functions.py:TestDataObservatoryFunctions.test_if_obs_search_is_ok
+```
+
+(replace the environment variables, test file, class and function according to your needs)
+
+TODO: we need to refactor the test code a little to avoid these hindrances
