[Django]-Django – how to unit test a post request using request.FILES

In the docs, the file field is called attachment, but in yours, it’s called file.

You don’t need name in your post data either — that refers to another field called name, not the name of the file that you are uploading.

Try the following:

def test_stuff(self): 
    myfile = open('....\file.csv','r') 
    response = self.client.post('/', {'file':myfile})

The way django’s testsuite does it is:

from django.core.files.uploadedfile import SimpleUploadedFile
f = SimpleUploadedFile("file.txt", b"file_content")

This way you don’t need to create a temp file and write to it, and you don’t need to mock a file (not as easy as it sounds).

Maybe I’m missing something here, but sounds like a job for a good mock library. I personally really like Mock. But, I fall into the camp that believes that your unit tests should be free of all external dependencies (like having to have a file named “file.csv” in a certain location, etc.)
