使用 FileField 对 Django 表单进行单元测试 [英] Unit Testing a Django Form with a FileField

问题描述

我有一个像:

#forms.py
from django import forms

class MyForm(forms.Form):
    title = forms.CharField()
    file = forms.FileField()


#tests.py
from django.test import TestCase
from forms import MyForm

class FormTestCase(TestCase)
    def test_form(self):
        upload_file = open('path/to/file', 'r')
        post_dict = {'title': 'Test Title'}
        file_dict = {} #??????
        form = MyForm(post_dict, file_dict)
        self.assertTrue(form.is_valid())

如何构造 file_dict 以将 upload_file 传递给表单?

How do I construct the file_dict to pass upload_file to the form?

推荐答案

到目前为止，我发现这种方法有效

So far I have found this way that works

from django.core.files.uploadedfile import SimpleUploadedFile
 ...
def test_form(self):
        upload_file = open('path/to/file', 'rb')
        post_dict = {'title': 'Test Title'}
        file_dict = {'file': SimpleUploadedFile(upload_file.name, upload_file.read())}
        form = MyForm(post_dict, file_dict)
        self.assertTrue(form.is_valid())
