If i do not want to unit test whole codebase, because it big 
enough and all tests take noticeable time to run.

So i trying this:

dmd -unittest mymodule.d

And getting error: "undefined reference to `main'"
But i don't want to run 'main' here, just unit test please.
Any idea how to test single module without putting 'main' in 
every module ?

Use the `-main` compiler switch:
"Add a default main() function when compiling. This is useful
when unittesting a library, as it enables the user to run the
unittests in a library without having to manually define an
entry-point function."

So, dmd -unittest -main mymodule.d
