如何在 Flask 中模拟 HTTP 身份验证进行测试？

Question

我刚刚为我的 Flask 应用程序设置了 HTTP 身份验证，但我的测试失败了。如何模拟 request.authentication 使测试再次通过？

这是我的代码。

server_tests.py

def test_index(self):
    res = self.app.get('/')

    self.assertTrue('<form' in res.data)
    self.assertTrue('action="/upload"' in res.data)
    self.assertEquals(200, res.status_code)

server.py

def check_auth(username, password):
    """This function is called to check if a username /
    password combination is valid.
    """
    return username == 'fusiontv' and password == 'fusiontv'

def authenticate():
    """Sends a 401 response that enables basic auth"""
    return Response(
    'Could not verify your access level for that URL.\n'
    'You have to login with proper credentials', 401,
    {'WWW-Authenticate': 'Basic realm="Login Required"'})

def requires_auth(f):
    @wraps(f)
    def decorated(*args, **kwargs):
        auth = request.authorization
        if not auth or not check_auth(auth.username, auth.password):
            return authenticate()
        return f(*args, **kwargs)
    return decorated

@app.route("/")
@requires_auth
def index():
    return render_template('index.html')

参考，您可以通过导入链模拟它。

假设 server_tests 导入 application 导入 server，您可能需要这样的东西：

server_tests.py

def setUp(self):
    application.server.request.authorization = MagicMock(return_value=True)
