在没有运行个 Bottle 服务器的情况下测试 Bottle 应用

Question

我正在遵循 Recipes of bottle 框架。

当我尝试下面的代码时

#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)

函数测试用例 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!'

当我运行 nosetests test_mywebapp.py 我遇到了以下错误。

nosetests test_mywebapp.py
E

QuickStart TestApp 提及。

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

我该如何配置？

需要，bottle server 运行ning，没有运行ning server，有没有办法测试bottle app？

Answer 1

感谢您发布堆栈跟踪。它清楚地表明这是导致 500:

的行

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

为什么不打印 app.get('/hello').status_code 的值以便了解发生了什么？

我也很确定你应该检查 status_int，而不是 status_code。

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