nit: unnecessary blank line?

[Hwanseung Lee, 2017/01/09 13:28:24]

Done.

It's better to align with the line just above.

[Hwanseung Lee, 2017/01/09 13:28:24]

Done.

Why do you leave FIXME comment here?

[Hwanseung Lee, 2017/01/09 13:28:24]

i will remove comment after implement all functions.
because when function added every time, we should add function name at every
expected file of tests.

[zino, 2017/01/08 17:52:30]

According to coding style guide, we should use TODO(hs1217.lee) instead of
FIXME.

[Hwanseung Lee, 2017/01/09 13:28:24]

Done.
