If they aren't run it is a bug somewhere. FWIW, the Tango runtime have a
hook to give you more control of the unittests you run. The following is
used to run Tango unittests (all files are built and linked in via
rebuild).

import tango.io.Stdout;
import tango.core.Runtime;

bool tangoUnitTester()
{
    uint countFailed = 0;
    uint countTotal = 1;
    Stdout ("NOTE: This is still fairly rudimentary, and will only report
the").newline;
    Stdout ("    first error per module.").newline;
    foreach ( m; ModuleInfo )  // _moduleinfo_array )
    {
        if ( m.unitTest) {
            Stdout.format ("{}. Executing unittests in '{}' ", countTotal,
m.name);
            countTotal++;
            try {
               m.unitTest();
            }
            catch (Exception e) {
                countFailed++;
                Stdout(" - Unittest failed.").newline;
                Stdout.format("   File '{}', line '{}'.", e.file,
e.line).newline;
                Stdout.format("     Message is : '{}'", e.msg).newline;
                if (e.info)
                    Stdout.format("     TraceInfo: {}",
e.info.toString).newline;
                continue;
            }
            Stdout(" - Success.").newline;
        }
    }

    Stdout.format ("{} out of {} tests failed.", countFailed, countTotal -
1).newline;
    return true;
}

static this() {
    Runtime.moduleUnitTester( &tangoUnitTester );
}

void main() {}
