Ok, thanks.
I haven't run into version(...) yet. Would I be correct if I
assumed that this version of void main: void main() {} would only
run if -unittest was in the command line?
Also, what should be in a unit test? Test cases to make sure
certain functions/classes are working as you intend them to?
If the unit tests pass, they don't print anything unless you
add statements to
them which do. You only get stuff being printed out on failure.
This works
particularly well for the command line (it's normal in
Unix-land for stuff to
print nothing on success unless them printing stuff out is
their job - this
makes it easier to pipe programs and the like). Some people
complain about it
from time to time, but that's the way it is. If you really want
them to print
something though, you can always add your own print statements.
If you compiled with -unittest, the unit tests run before main
does, so if all
of your tests pass, then your program will run normally after
the unit tests
have been run.
It's not uncommon for people to do something like this so that
they can have
the unit tests run without running their actual program:
version(unittest) void main() {}
else void main()
{
//Your normal main...
}
