[PYTHON] [Django] Test to send a file by POST and check the returned context [TDD]

I want to test a page with a form!

Previous article As I said, I would like to make a test for a page with a Form. But for some reason I got an error and couldn't test. I thought I should test the Form for the time being, but when I thought about it, I couldn't test the processing after that, so it didn't help. After all, I have to POST and check the context.

What was the solution and what was it?

The solution is as follows. All I had to do was open it with open, insert the file handler, and POST it.

tests.py

from django.test import TestCase, Client
from django.contrib.auth.models import User

class Test_Model_Create(TestCase):
    def setUp(self):
        #Create test user
        self.user = User.objects.create_user(username='tdd', email='[email protected]', password='test_pass') 
        self.client=Client()
        #Login
        self.client.login(username='tdd', password="test_pass")  

    def test_step1(self):      
        with open('./path/test.csv') as f:  
            data = {
                "nametest" : "test",
                "file_data" : f
            }
            response = self.client.post('/model_create/form/', data)
        self.assertIn('file_data', response.context, "file in context_data not included")

It's okay like this.

The point that was stuck is

--I did POST after closing the file. --I passed a file instead of a file handler (File (open ('./ path / excel_test.csv')))

That was the reason. I also tried using RequestFactory instead of Client, but that was the reason ...

Multiple file upload test

By the way, I have to give two files this time, but in such a case it seems that I can write as below.

tests.py

        with open('./path/testA.csv') as fa,open('./path/testB.csv') as fb:    
            data = {
                "name" : "test",
                "file_dataA" : fa,
                "file_dataB" : fb
            }
            response = self.client.post('/model_create/form/', data)

The with sentence is really easy. It's amazing.

Summary

I'm really wondering why I was so worried. I want to reduce Pokamis.
