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.
