We kept this separate considering to test Profile and Service separately.
Noted your suggestion we will try to have it in same file.

In function static struct bt_mics *mics_new(struct gatt_db *db) by default the mics->mute_stat is set to MICS_MUTED.
As per test specs, MICS/SR/SPE/BI-02-C -> Initial condition: The IUT has set its Mute state to Disabled (0x02).
To verify this Unit test case we have to modify the initial state of mics->mute_stat to MICS_DISABLED in code then it works fine.
