+# Testing
+
+In order to test the data and the functions created under the script avaialble in this folder, you will need to run `bash test.sh` from `test/data` and `test/functions`. These functions test the amount of geometries generated, their bounding box, and the bounding box of the results generated by the geocoder functions. The tests also ensure a minimum quality in the synonyms table/function, checking that the official name (in English) for the regions is recognised.
