You can override this behavior by defining your own unittest function:

import core.runtime;
import std.stdio;
import std.string;
import std.path;

bool testRunner()
{
    foreach (m; ModuleInfo)
    {
        if (m is null)
            continue;

        if (auto fp = m.unitTest)
        {
            try
            {
                fp();
            }
            catch (Throwable e)
            {
                writeln(e);
            }
        }
    }

    // stop execution after tests are done
    return false;
}

shared static this()
{
    Runtime.moduleUnitTester(&testRunner);
}

unittest
{
    writeln("in unittest");
    assert(1);
}

void main()
{
    writeln("not in main");
}

--------------

I've written a similar test system where I can also set these at runtime via
getopt switches:

- specify which modules to run the tests on (--testMods=foo.bar)
- ditto but set modules which should *not* have their tests ran on
(--ignoreMods=foo.bar.doo)
- specify whether to run the unittests, and whether to run main() if the tests
were successful

I might write a DWiki entry later on how to do this if there's any interest.
