異なるボタンによるPOSTのテストについて
tutorial/urls.py
"""tutorial URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.2/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))

このようなテストが書ける。
from django.test import TestCase
from django.test.client import Client
class SubmitTests(TestCase):
def test_submit(self):
c = Client(enforce_csrf_checks=False)
response1 = c.post('/tutorial/sample_template', {'name': '1', 'product': '車', 'action': '送信２'})
response2 = c.post('/tutorial/sample_template', {'name': '2', 'product': '馬', 'action': '送信１'})
self.assertEqual(response1.status_code, 200)
ここで、Clientメソッドは、Client()でもデフォルトでscrfがオフになっているのでcsrfについては設定する必要はない。 異なるボタンに反応させるには、dic型でボタンの名前と値を指定すれば良いとわかった。
