lcov - create and use gcad files while running

Question

I want to use lcov in some tests I run. Tests are not part of the binary I compiled with lcov. I noticed that lcov create gcda files only after binary is ended. The problem is that I want to run several tests without restarting the binary and still be able to pause before a new test to collect data from gcda. Do you know how to make lcov to create gcda files while running?

Thanks.

In the project we call __gcov_flush();
