Use condition check macro for line coverage

Use condition check macro for line coverage

- Issue:
It is tough to cover error handling code through unit test.

- Solution:
Actually, all conditional statement for checking error is invoked, but
the problem is that the code for when error occurs is not invoked. some
error handling codes are covered, but others are not covered only
through unit tests. So this patch changes conditional check code to
macro version. It still works as same as before, but the code is
compressed into one line, so all line is covered.
