Flask unittest AssertionError：弹出错误的请求上下文

Question

我正在使用python 2.7，Flask和unittest， 我正在尝试模拟一个会话以在登录后发布请求。

这是做什么：

$products_count = 0;

foreach($store->products() as $product)
{
   if($product->status == 1)
   {
     $products_count++;
   }
}

dd($products_count);

这就是我得到的

def test_06_fill_form(self):
      with self.app as c:
          with c.session_transaction() as sess:  
              sess['user'] = 'yo'
              datas={
                  "nom":"joe",
                  "prenom":"doe",
                  "company": "Google",
                  "email": "jdoe@joe.com",
                  "phone":"2343423"
              }
              print sess
              self.assertTrue(sess.get('user') == 'yo')
              response = c.post('/thanks',data=datas)
              self.assertIn(b'Merci!', response.data)

我在stackoverflow上发现了

AssertionError: Popped wrong request context.  (None instead of 
<RequestContext 'http://localhost/' [GET] of flask_app>)

但这不起作用

这是一堆完整的错误

app.config['PRESERVE_CONTEXT_ON_EXCEPTION'] = False
