This is an alternative to #406.

it('database test', function () {
    
    expect(new Foo())
        ->foo->toBe('foo')
        ->match(DB::getDriverName(), [
            'mysql'  => fn ($foo) => $foo->mysql->toBeTrue(),
            'sqlite' => fn ($foo) => $foo->sqlite->toBeTrue(),
        ])
        ->bar->toBe('bar');

});

it('builder test', function ($driver) {
    
    expect(new Builder())
        ->match($driver, [
            'mysql'   => fn ($b) => $b->where('...')->toBe(...),
            'postgre' => fn ($b) => $b->whereRaw('...')->toBe(...),
        ]);
    
})->with([
    'mysql',
    'postgre',
]);

For more examples, please review the tests.

Thank you.

I actually like this a lot. It's a sharp knife, for sure, but a valuable one I think.
