This standard module for writing unit tests in Python has been developed for a long time. Unit testing is a method of determining the correctness of a single function isolated from a larger codebase. In the scripts google_place_api.py, I create a Python class named “Place”, which contains one place’s latitude, longitude, name, ID and its rating; then I create a function search_place(gps='gps', api_key='api_key') in order to get places’ information by Google Places API … Using unittests python package and requests modules, we can test REST API in test automation.
