> Hard to read, but apparently the test wants to perform two checks at once:
> {noformat}
> assert response.status_code == requests.codes.ok\
> and string_to_search in response.text, "Offending url: " + input_url
> {noformat}
> The return code part appears to match. So the question is whether the string
> "total-file-size-bytes" appears in the output.
> Tried building from latest master and hitting my local server with the same
> URL as above. The page reported:
> {noformat}
> num-partitions: 24
> total-file-size-bytes: 489934
> {noformat}
> So, the string match part should work.
> General observation: it is not helpful at all to include an and in an
> {{assert}} statement: doing so makes debugging very difficult. Please use one
> condition per {{assert}}.
> Net result is that there is no obvious failure here; someone will need to did
> into it more deeply.
