#15826 closed Bug (fixed)

TestCase assertions should work with TemplateResponse

Description

When using assertContains for testing class based generic views or other views that returns TemplateResponse, following error is raised:

ContentNotRenderedError: The response content must be rendered before it can be accessed.

Example:

        response = SomeView.as_view()(request)
        self.assertContains(response, 'some content')

This can be avoided with adding response.render() before assertion is called, but in my opinion assertContain should check if content is rendered instead.

I added a check if the response handed to assertContains is a TemplateResponse, and if so, will render it.
Added the same check to assertNotContains for consistency.

I do an explicit check for instanceof(response, SimpleTemplateResponse), but perhaps duck typing for any response with response.render() would be more appropriate/useful?

Replying to mmcnickle:

Yes, I think it'd be better to check for a callable response.render() rather than using isinstance. This (checking for the render method) is what Django already does in its normal response handling, after template response middleware.
