get errors from client post method in django testing

Question

Is there a quick way to get the errors from a form submission when using Client in a django test?

Here's a code snippet:

with open(good_path) as fp:
            data = {
                'account': account_id,
                'date': date,
                'file': fp
            }
            response = client.post(reverse('myapp:form-page'), data)

The page is not redirecting correctly (response=200) and I can see in response.content that there is an error being returned.

Is there a quick way to isolate the error? I was hoping for something like response.errors, similar to a forms instance.

Assuming the underlying view uses a template to render its response, you can access the context of that template using response.context. So, for example, if your view does something like this:

form = MyForm(request.POST)
if form.is_valid():
    return redirect(...)
return render(request, 'template.html', {'form': form})

your test can access response.context['form'].errors to see the form errors.
