Hi everyone,
I’ve been stuck at the ‘spend chart’ part of this project for over two weeks now, with no end in sight. The output looks identical but i’m getting one failure which i know ,most likely, is due to newlines and spaces but i can’t figure it out even when i set self.maxDiff=None, as suggested.
The error is:
Diff is 819 characters long. Set self.maxDiff to None to see it. : Expected different chart representation. Check that all spacing is exact.
I’ve seen 2-3 similar posts here but for some reason there was no response, i hope this one will fare better .
Thanks in advance to anyone that will take the time to help
