Exclude un-testable files and fix test launch option

Exclude un-testable files and fix test launch option

- Issue:
Line coverage result by automatic checker is not good.

- Solution:
This patch excludes some files that are not target for testing user APIs. This
repository is for TTS framework code, so there are code for not only client but
also server and settings. Those code are not invoked or refered when the test
case of user APIs run, so we exclude those files from line coverage checking
through this patch.
And also, this patch adds launch option for testing. This is because for
checking the test result using journal log.
