Summary : I have a method which i would like to test. This methods involves connecting the database,extracting the result (from sql query) and saving it into a data frame. I would like to know, is there a way I can mock the result retrieved from the SQL query? I tried unittest library, created a dataframe like the one received from the SQl query. But I am unable to figure out how can I pass this variable to the method while testing. Please share your insights. My method is something like : try: db_connect = sqlite3.connect("address_zip.db") db_cur = db_connect.cursor() db_cur.execute(""" Select STD_ADDRESS,STD_CITY,STD_STATE from address""") sql_result=pd.read_sql_query(""" Select STD_ADDRESS,STD_CITY,STD_STATE from address""",db_connect) df = pd.DataFrame(sql_result, columns=['STD_ADDRESS', 'STD_CITY', 'STD_STATE']) print(f"The data from database is :\n {df}") db_cur.close() db_connect.close() except Exception as e: print(f"DB exception: {e}") return df There are several actions done on the variable "df" in the original code, my agenda is to mock this object df. But I am unable to understand how? Sorry this may be very basic question, I am new to python. Continue reading...
