Function TEST

test/test_unitqueue.cpp:17–31

Create CUnitQueue with queue size of 4 units. The size of 4 is chosen on purpose, because CUnitQueue::getNextAvailUnit(..) has the following condition `if (m_iCount * 10 > m_iSize * 9)`. With m_iSize = 4 it will be false up until m_iCount becomes 4. And there was an issue in getNextAvailUnit(..) in taking the very last element of the queue (it was skipped).

/// And there was an issue in getNextAvailUnit(..) in taking
/// the very last element of the queue (it was skipped).
