[PATCH v2 3/3] kunit: tool: move kunitconfig parsing into __init__, make it optional

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



LinuxSourceTree will unceremoniously crash if the user doesn't call
read_kunitconfig() first in a number of functions.

And currently every place we create an instance, the caller also calls
create_kunitconfig() and read_kunitconfig().
Move these instead into __init__() so they can't be forgotten and to
reduce copy-paste.

The https://github.com/google/pytype type-checker complained that
_config wasn't initialized. With this, kunit_tool now type checks
under both pytype and mypy.

Add an optional boolean that can be used to disable this for use cases
in the future where we might not need/want to load the config.
