使用 unittest POST 错误 500 测试 Flask 网络应用程序

Question

这是我的 test.py 文件：

import unittest, views, json

class FlaskTestCase(unittest.TestCase):

def setUp(self):
    self.app = views.app.test_client()

def test_index(self):
    rv = self.app.get('/')
    assert 'Hamptons Bank' in rv.data

def test_credit(self):
    response = self.app.post('/credit', data=json.dumps({
            'amount': '20',
            'account': '1'
        }), content_type='application/json')

    print response.data
    assert 'Deposit of 20 to account 1' in response.data


if __name__ == '__main__':
     unittest.main()

test_index 方法工作正常，但 self.app.post 不断返回（打印 response.data）：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p>

我的views.py中的方法如下：

@app.route('/credit', methods=['POST'])
def credit_account():
  bank = Bank()

  amount = int(request.json["amount"])
  depositCommand = DepositCommand(find_account(request.json["account"]), amount)
  bank.execute(depositCommand)

  message = "Deposit of " + str(request.json["amount"]) + " to account "+str(request.json["account"])
  return message

我做错了什么？

这是我第一次测试 Flask web 应用程序，所以我还是有点困惑！

谢谢:-)

（来自我上面的评论）：测试时，您应该设置 app.config['DEBUG'] = True 和 app.config['TESTING'] = True.
