# `sys.prefix/bin/python -m conda` (or the Windows equivalent).
# .. and the source code for `conda` is put on `sys.path` via `PYTHONPATH` (a bit gross but
# less so than always requiring `cwd` to be the root of the conda source tree in every case).
# If you do not want this to happen for some test you must pass dev=False as a kwarg, though
# for nearly all tests, you want to make sure you are running *this* conda and not some old
# conda (it was random which you'd get depending on the initial values of PATH and PYTHONPATH
# - and likely more variables - before `dev` came along). Setting CONDA_EXE is not enough
# either because in the 4.5 days that would just run whatever Python was found first on PATH.
