Python3 and Robot Framework b'SUCCESS' Error

Question

Currently experimenting (or trying to) with Robot Framework. I'm using Python-3 and I've managed to get a version of the framework for python 3.

pip install robotframework-python3

I downloaded the QuickStart guide which was recommended on the GitHub page and I had to convert some of it from Python2 to Python 3. This just included to minor changes, removing commas from try/except and a few brackets around prints. This ran the first test of tests wonderfully. When it came to running the other tests with the command:

pybot QuickStart.rst

I had this error in the .html error logs it produces:

Expected status to be 'SUCCESS' but was 'b'SUCCESS''.

This error was common across all of the tests. I understand that it's related to a binary response (vague guess from memory).

Does anybody know of a solution?

N.B Robot Framework 2.8.7 (Python 3.3.3 on darwin)

Many Thanks.

I also did the same thing as you and encountered the issue. Apart from modifying the sut/QuickStart.rst, you may also need to modify the lib/LoginLibrary.py to append one more parameter, i.e. universal_newlines=True to subprocess.Popen(...) such that it will be treated as string instead of byte sequence. The QuickStart.rst test cases all pass now :)

You may check the reference https://docs.python.org/3/library/subprocess.html#subprocess.Popen
