unittest blocks are skipped completely by the compiler when the 
-unittest command line option is not passed. So you can leave 
unittest code embedded in between the rest (specially for proper 
unit tests of functions and classes) and there is no need to 
worry about file separation. Even when you write a separate file 
with tests, all its code inside unittest blocks can be skipped 
for the compiler.


In the case of dub, it has a dedicated option, "dub test" instead 
of "dub build" or "dub run"

If you are using the D unittests in your source you can

Or you can keep the tests separate and compile these test 
separately like you are doing in your C project. I use this

So to use D 'unittest' I am required to include the main.d 
module file in the tester executable?


If you pass the `-main` flag to the compiler when building your 
tester executable, it will add an empty main function for you. 
For example:


dmd -unittest -main mymodule.d

test_exe = executable('test_exe',
sources: [ 'test.d' ],
d_args: [ '-main' ],
d_unittest: true,
include_directories: exe_dir)

Unit tests are part of the language in D:

https://dlang.org/spec/unittest.html

These are compiled when you (or whatever build system you use) 
pass the argument -unittest to the compiler.



If you never herd about Meson before:

D has an "official" build manager, called dub. Of course you're 
free to use another one you prefer.


https://dub.pm/getting_started

PS also embedded documentation is part of the language (no need 
for e.g. doxygen):
