PowerShell and some wrapper scripts on Windows occasionally strip
or reorder the `--` separator before Blender sees it, dropping the
pytest args into Blender's positional file-load slot ("File format
is not supported"). The env var carries the same args via a
shell-evaluation-free channel. Default `--` path is byte-identical
to the pre-change behaviour.

Requires pytest installed under blender.
|
|
|
|
Usage:
|
|
blender -b -P runpytest.py -- ARGS
|
|
|
|
Alternative (when the calling shell strips or reorders the ``--`` separator
|
|
before it reaches Blender — observed with some PowerShell / wrapper-script
|
|
invocations on Windows): pass the same pytest args via the
|
|
``BONSAI_TEST_ARGS`` environment variable as a single shell-quoted string
|
|
and invoke without ``--``::
|
|
|
|
$env:BONSAI_TEST_ARGS = "test/bim/ -x -q"
|
|
blender -b -P runpytest.py
