   Is your feature request related to a problem? Please describe. It currently does not seem possible to execute the functional tests in parallel when running make cov. Thus it makes running this command very slow.

   https://github.com/bitcoin/bitcoin/blob/6d40a1a7e7f09ff2c32e53237f968adf8300d028/Makefile.am#L215-L247

   Describe the solution you’d like Run test coverage functional tests with make cov -j8 or FUNCTIONAL_TESTS_JOBS=8 make cov ?

   Maybe we could replace --enable-extended-functional-tests with a TEST_RUNNER_EXTRA env var, similar to the one in ./ci/?

   Locally I use an ugly sed hack for now:

   0sed -i 's|functional/test_runner.py |functional/test_runner.py --timeout-factor=10 --exclude=feature_dbcrash |g' ./Makefile.am

   This was probably resolved by cmake.

   If this is not the case then please leave a message here and we can reopen it.

   This was probably resolved by cmake.

   From the “Compiling for test coverage” section of Developer Notes:

   To enable test parallelism:

   cmake -DJOBS=$(nproc) -P build/Coverage.cmake
