[PATCH 1/5] kunit: tool: drop mostly unused KunitResult.result field

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

 



This field is only used to pass along the parsed Test object from
parse_tests().
Everywhere else the `result` field is ignored.

Instead make parse_tests() explicitly return a KunitResult and Test so
we can retire the `result` field.
