BasicObject
Object extensions for Minitest::Mock.
Add a temporary stubbed method replacing name
for the duration
of the block
. If val_or_callable
responds to
call, then it returns the result of calling it, otherwise returns the value
as-is. If stubbed method yields a block, block_args
will be
passed along. Cleans up the stub at the end of the block
. The
method name
must exist before stubbing.
