Flask testing?

Question

Software testing

It is necessary to test the functionality of the server written in Flask. Moved application initialization to create_app()

from flask import Flask

def create_app(debug=False):
    app = Flask(__name__)
    app.debug = debug

    return app

Next, I write tests using Nose . And there was such a problem, if I have several test cases, then the same application is used. In other words, with a new case, the server remains the same, which is rather inconvenient, because the cases are written taking into account that the server has just risen.
I googled, found that you can create factories in Flask, just through create_app (), but no matter how I tried, there is still one single instance of my application. Or maybe you can somehow drop it and restart it?

I'll listen to any ideas :)

There is a book by Miguel Greenberg about web development with Flask. I recommend reading the sections about testing. I deliberately will not give how, because. better than Grinberg, hardly anyone can explain it better. But. I would like to draw your attention to the fact that it is better to use py.test + pyhamcrest instead of Nose , then your tests will be more expressive and you will be able to see better "What would .. break that?"
