text dump instead of graph

[zyxue]

I am seeing this instead of graph

\x1b[0m\x1b[32m\u2713\x1b[0m\x1b[32m\u2713\x1b[0m\x1b[32m\u2713\x1b[0m\x1b[32m\u2713\x1b[0m\x1b[32m\u2713\x1b[0m\x1b[32m\u2713\x1b[0m                                                               \x1b[32m98%...
Results (0.73s):
      85 passed

The dump is very very long. It's supposed to be rendered to graph. I am inside a docker container, what could be the reason, please? I have tested color display, it's ok. The 85 passed part is in green.

[The-Compiler]

Do you run docker with -it - if not, does that change anything?

[zyxue]

Yes, I specified --rm -t -i, and then py.test interactively inside the docker container.

[dobesv]

I'm seeing the same issue if I run tests inside docker, it looks like it is escaping the control character as \x1b perhaps? Very odd. I am using docker run -it ...

[dobesv]

Here's some more data points:

>>> import sys
>>> sys.stdout.encoding
'ANSI_X3.4-1968'
>>> import py.io
>>> tw = py.io.TerminalWriter(sys.stdout)
>>> tw.write(u'\r \x1b[36mfilename.py\x1b[0mtest_name\x1b[0m \x1b[32m\u2713\x1b[0m\n\n')
\r \x1b[36mfilename.py\x1b[0mtest_name\x1b[0m \x1b[32m\u2713\x1b[0m\n\n>>> 

Note how when the encoding is 'ANSI_X3.4-1968' it puts in the escape characters.

Outside of docker this works fine:

>>> import sys
>>> sys.stdout.encoding
'UTF-8'
>>> import py.io
>>> py.io.TerminalWriter(sys.stdout).write(u'\r \x1b[36mtest_file.py\x1b[0mtest_name\x1b[0m \x1b[32m\u2713\x1b[0m\n\n')
 test_file.test_name ✓

[dobesv]

Workaround:

# PYTHONIOENCODING=UTF-8 python
>>> import sys
>>> sys.stdout.encoding
'UTF-8'
>>> import py.io
>>> py.io.TerminalWriter(sys.stdout).write(u'\r \x1b[36mtest_file.py\x1b[0mtest_name\x1b[0m \x1b[32m\u2713\x1b[0m\n\n')
 test_file.pytest_name ✓

So, setting PYTHONIOENCODING=UTF-8 seems to resolve the problem, as long as your terminal actually supports UTF-8 encoding.

[dobesv]

I do wish I knew why sys.stdout.encoding was UTF-8 outside docker and ANSI_X3.4-1968 within.

[The-Compiler]

ANSI_X3.4-1968 is a fancy way to say ASCII, so I'm guessing locale will show a C locale inside docker, i.e. the locale was not generated/configured properly.

[dobesv]

Inside docker:

root@d4cf4ef0c83f:/# locale
LANG=
LANGUAGE=
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=

Outside docker:

$ locale
LANG=en_CA.UTF-8
LANGUAGE=
LC_CTYPE="en_CA.UTF-8"
LC_NUMERIC="en_CA.UTF-8"
LC_TIME="en_CA.UTF-8"
LC_COLLATE="en_CA.UTF-8"
LC_MONETARY="en_CA.UTF-8"
LC_MESSAGES="en_CA.UTF-8"
LC_PAPER="en_CA.UTF-8"
LC_NAME="en_CA.UTF-8"
LC_ADDRESS="en_CA.UTF-8"
LC_TELEPHONE="en_CA.UTF-8"
LC_MEASUREMENT="en_CA.UTF-8"
LC_IDENTIFICATION="en_CA.UTF-8"
LC_ALL=

Anyway, it this point it's pretty clearly a docker issue, not a pytest-sugar issue. This issue should hopefully serve as a reference for other who run into this problem.

[dobesv]

Or instead of setting PYTHONIOENCODING, setting up the locale correctly in the Dockerfile should work, and might help with other things that rely on locale as well:

# Set the locale
RUN locale-gen en_US.UTF-8  
ENV LANG en_US.UTF-8  
ENV LANGUAGE en_US:en  
ENV LC_ALL en_US.UTF-8

I've got this error too without using Docker but Tox.

But if i use directly py.test it works :

Any idea how fix that ?

[zyxue]

Just to add that this happens when the test is run on a jenkins server, as well if the output is sent to the browser.

[Sup3rGeo]

Same thing happens to me on Windows 10 cmd.
