D does not recognise any special testing directories afaik. But 
you'll get the same affect as in rust if you have your 
integration tests in a file that is not the modules you are 
testing and run it after building the main library - or during 
even.

With Dub it's quite easy to set up, you can see the optional 
package as an example [0]. There's a tests directory that does 
not have access to the optional package's internals. There's also 
a unittest-compat configuration in dub.json that tests the 
package alongside vibed (another d package)

For auto mocking, the only thing I've see that provides some 
functionality is the unit-threaded package. But I've never tried 
it.
