Test bottle app without running bottle server

问题

I am following Recipes of bottle framework.

When I try below code

#filename: mywebapp.py
from bottle import Bottle, run, request

app = Bottle()

@app.get('/hello')
def hello():
    return "Hello " + request.get_header('name')

if __name__ == '__main__':
    run(app, host='localhost', port=80)

Function testcase with TestApp

#filename: test_mywebapp.py
from webtest import TestApp
import mywebapp

def test_functional_hello_world():
    app = TestApp(mywebapp.app)
    assert app.get('/hello').status_code == 200
    assert app.get('/hello', headers=dict(name='World!')).text  == 'Hello World!'

When I run nosetests test_mywebapp.py I got below error.

nosetests test_mywebapp.py

QuickStart on TestApp mention.

If your WSGI application requires any configuration, you must set that up manually in your tests.

How I can configure this?

It needs, bottle server running, is there any way to test bottle app without running server?

回答1:

Thanks for posting the stack trace. It clearly indicates that this is the line that is causing the 500:

assert app.get('/hello').status_code == 200

Why don't you print the value of app.get('/hello').status_code so you can learn what's happening?

I'm also pretty sure that you should be checking status_int, not status_code.

assert app.get('/hello').status_int == 200
