More precisely, inject all options provided in .pytest_guix_options.json,

except options whose plugin is indeed installed.
|

|
|
For example, if the json file records --cov:
|
|
if the pytest_cov module is installed, its --cov will be used.
|
|
otherwise, --cov is ignored (read by this parser, but nothing is done
|
|
with it).
|
|
|
|
Flags can be given with additional keyword arguments in a json object.
|
|
If the json object is not given, fallback to the default
|
|
{"action": "append", "nargs": "?"}. In practice, these arguments are only
|
|
mandatory for the store_true and store_const actions to avoid eating other
|
|
arguments.
|
|
|
|
This allows to remove development packages, which are not required at build
|
|
time while at the same time avoiding the need to adjust test options in
|
|
pyproject.toml or other configuration files.
