too?
Here's the finest-grain way of running tests that is available (that I know
of): Use `ctest -VV -N -R cpp-url-test` to ask ctest to print you the test
command. Then add --help at the end, and you'd get a help text from Catch1:

Similarly, if you run `VERBOSE=1 make coverage`, it will print you what
commands it is running.
To get a clean coverage result, you have to delete the temporary files that
contain previously recorded coverage, then run a test (the command from ctest),
and then run the command generating the html report (from make coverage).
