本文实例讲述了Python Django框架单元测试之文件上传测试。分享给大家供大家参考，具体如下：

Submitting files is a special case. To POST a file, you need only provide the file field name as a key, and a file handle to the file you wish to upload as a value. For example:

> c = Client()
> with open('test.jpg') as fp:
...   c.post('/account/avatar_upload/',{'avatar':fp})

测试文件上传其实没有什么特殊的，只需要指定后端接受请求数据的对应键值即可

(The name avatar here is not relevant; use whatever name your file-processing code expects.)在这里avatar是关联的，对应着具体的后端处理程序代码，eg:

class Useravatar(View):
  def __init__(self):
    self.thumbnail_dir = os.path.join(STATIC_ROOT, 'avatar/thumbnails')
    self.dest_dir = os.path.join(STATIC_ROOT, 'avatar/origin_imgs')
  @method_decorator(login_required)
  def post(self, request):
    nt_id = request.session.get('user_id', 'default')
    user = User.objects.get(pk=nt_id) if User.objects.filter(pk=nt_id).exists() else None
    avatarImg = request.FILES['avatar']
    if not os.path.exists(self.dest_dir):
      os.mkdir(self.dest_dir)
    dest = os.path.join(self.dest_dir, nt_id+"_avatar.jpg")
    with open(dest, "wb+") as destination:
      for chunk in avatarImg.chunks():
        destination.write(chunk)
    if make_thumb(dest,self.thumbnail_dir):
      avartaPath = os.path.join(STATIC_URL, 'avatar/thumbnails', nt_id + "_avatar.jpg")
    else:
      avartaPath = os.path.join(STATIC_URL, 'avatar/origin_imgs', nt_id + "_avatar.jpg")
    User.objects.filter(nt_id=nt_id).update(avatar=avartaPath)
    return render(request, 'profile.html', {'user': user})
