[Development] [autotests] Why the objects are used in 'heap' instead of 'stack'

[Denis Shienkov]

Hi all,

Is there are any reasons why the tested objects are created in 'heap' 
instead of 'stack' (in the majority of cases)?

E.g. we can look on 
\qtbase\tests\auto\network\socket\qtcpsocket\tst_qtcpsocket.cpp as example,
where in each test are used the new/delete:

void tst_QTcpSocket::foo()
{
     QTcpSocket *socket = new QTcpSocket;
     // make tests
     delete socket;
}

instead of

void tst_QTcpSocket::foo()
{
     QTcpSocket socket;
    // make tests
}

BR,
Denis
