It may happen that textOnStandardOutput() sends multi lines,
even when they were sent by two separate std::cout with std::endl.
Instead of checking whether the 2nd expected line starts with
the magic word, check whether the message contains it.
Limit timeouts so that the test should pass about 3 seconds faster.
