When debugging tests you frequently need to inspect response content, making a pdb. set_trace() breakpoint and printing response.content

but html isn't enough human readable (even for programmers :D) so, why not open it in your browser? Suposse you save this code in utils.py and you break your testcase as this:

response = self.client.get(self.url)
import pdb; pdb.set_trace()

Then: 

(pdb) from utils import load_response_on_firefox
(pdb) load_response_on_firefox(response)

Ta-Da!

        _, filepath = mkstemp(text=True)

    f.write(response.content)
    f.close()
    return filepath

    subprocess.call(['firefox', fpath])
