django-ajax-uploader - ошибка модульного теста из-за AssertionError

1 голос
/ 08 января 2012

Я использую следующее приложение: https://github.com/GoodCloud/django-ajax-uploader

Теперь я написал несколько тестов для проверки успешной загрузки файла.Все работает нормально, пока не дойдет до следующего примера кода.

https://github.com/GoodCloud/django-ajax-uploader/blob/master/ajaxuploader/views.py#L53

success = backend.upload(upload, filename, is_raw)

При запуске я получаю следующую ошибку: 

AssertionError: Cannot read more than the available bytes from the HTTP incoming data.

В отладке я нашелвышло, что при остановке теста в этой точке и вызове ... 

request.POST

... тест работает нормально, ошибок не появляется и файл загружается.Что за....?Может быть, файл загружается только при остановке теста и в ожидании его загрузки?

Мой след: 

AssertionError: Cannot read more than the available bytes from the HTTP incoming data.
