For the rationale see e.g. this thread:

https://forum.dlang.org/post/wnydmelyxprvhsxewums@forum.dlang.org

A trick around this is sth. like:

version(D_Ddoc)
{
     enum doUnittest = true;
}
else
{
     version(unittest)
     {
         enum doUnittest = true;
     }
     else
     {
         enum doUnittest = false;
     }
}

and then `static if (doUnittest)` the tests inside. For example 
ndslice uses a similar pattern.
