Review comment:
Thanks!
BTW I want to mention that I also added 1 line at the end of the previous
testBitOrFunction(). I noticed that without this line, the previous bit_or test
will always no matter what expected result I set, which makes it an invalid
test.
It will be good if you can take a look.
