title: Angular2 material 'md-icon' is not a known element with Karma / Jasmine
body: <p>I'm working on an Angular2 application using 
  @angular/material 2.0.0-alpha.11-3
  angular-cli 1.0.0-beta.19-3
  karma 1.2.0
  karma-jasmine 1.0.2</p>
  
  <p>Running it works fine but a couple of the tests where the template has a button with md-icon fail with template errors:</p>
  
  <pre><code>ERROR: 'Unhandled Promise rejection:', 'Template parse errors:
  'md-icon' is not a known element:
  1. If 'md-icon' is an Angular component, then verify that it is part of this module.                                
  2. If 'md-icon' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schemas' of this component to suppress this message
  </code></pre>
  
  <p>My app.module.ts:</p>
  
  <pre><code>import { MaterialModule } from '@angular/material';
  
  @NgModule({
    declarations: [
      AppComponent,
      LinearProgressIndicatorComponent,
      MyNewDirectiveDirective,
      MyNewServiceDirective,
      HeaderComponent,
      MenuComponent,
      WatchpanelComponent,
      InputComponent
    ],
    imports: [
      BrowserModule,
      FormsModule,
      HttpModule,
      NgbModule.forRoot(),
      MaterialModule.forRoot(),
    ],
    exports: [ MaterialModule ],
    providers: [LocalStorage],
    bootstrap: [AppComponent]
  })
  export class AppModule { }
  </code></pre>
  
  <p>watchpanel.component.spec.ts:</p>
  
  <pre><code>import { async, ComponentFixture, TestBed } from '@angular/core/testing';
  import { By } from '@angular/platform-browser';
  import { DebugElement } from '@angular/core';
  import { WatchpanelComponent } from './watchpanel.component';
  
  describe('WatchpanelComponent', () =&gt; {
    let component: WatchpanelComponent;
    let fixture: ComponentFixture&lt;WatchpanelComponent&gt;;
  
    beforeEach(async(() =&gt; {
      TestBed.configureTestingModule({
        declarations: [ WatchpanelComponent ] // declare the test component
      })
      .compileComponents();
  
      fixture = TestBed.createComponent(WatchpanelComponent);
      component = fixture.componentInstance;
      fixture.detectChanges();
  
    }));
  
    // beforeEach(() =&gt; {
    //   fixture = TestBed.createComponent(WatchpanelComponent);
    //   component = fixture.componentInstance;
    //   fixture.detectChanges();
    // });
  
    it('should create', () =&gt; {
      expect(component).toBeTruthy();
    });
  });
  </code></pre>
  
  <p>As I understood it @angular/material now contains the only module needed to import, MaterialModule. I tried importing the MdIconModule from @angular2-material/icon with no success. What am i doing wrong ?
  Thanks in advance </p>
