test mongo db connect

test_mongodb.py

import pymongo
import datetime

client = pymongo.MongoClient("mongodb://localhost/test")

db = client.test_database

post = {
"author": "Mike",
"text": "My first blog post!",
         "tags": ["mongodb", "python", "pymongo"],
         "date": datetime.datetime.utcnow()
		 }
posts = db.posts
post_id = posts.insert_one(post).inserted_id

could be use to test if mongo db could be connect or not successfully
