How do I force pytest to show the results in color, even when writing to a pipe? There does not seem to be any command line option to do so.

As of 2.5.0 py.test has the option --color=yes
As of 2.7.0, it should be also possible to do:
export PYTEST_ADDOPTS="--color=yes"
The "py" library that pytest uses will not use color if it doesn't detect a terminal. I ended up making a change to it to allow setting an enviroment variable (PY_FORCE_COLOR=1
) to force the color.
I submitted a PR for this: https://bitbucket.org/hpk42/py/pull-request/10/add-an-environment-variable-py_force_color
For now, I install my fork to do this:
pip install hg+https://[email protected]/msabramo/py@py_force_color

4as said there, i think we should introduce a direct
--color=yes|no|auto
option to pytest.– hpk42Commented Nov 18, 2013 at 9:53 -

There's a library that I have not tried but sounds promising. It's pytest-rich
. See: https://github.com/nicoddemus/pytest-rich
