Just spent a couple hours on this. It looks like Angular now provides a FakeMatIconRegistry. It squashed about 90% of the karma warnings, but still a few remain...

Had to do a lot of this:

TestBed.configureTestingModule({

    imports: [
        ...
        MatIconModule,

    providers: [
        ...
        { provide: MatIconRegistry, useClass: FakeMatIconRegistry }
    ]
}).compileComponents();
