无法在Angular 2.0.0测试中加载.html

beforeEach( async(() => {
        TestBed.configureTestingModule({
            declarations: [
                SomethingComponent
            ]
        }).compileComponents(); // compile template
    }));

    beforeEach(() => {
        fixture = TestBed.createComponent(SomethingComponent);
        comp = fixture.componentInstance;
    });

    it('test',async(() => {
        fixture.detectChanges();
        expect(true)
    }));

给定组件：

@Component({
    templateUrl: 'app/components/something/something.component.html'
})

我收到错误：

Firefox 48.0.0 (Mac OS X 10.11.0)

我想这可能是因为配置没有正确设置.我正在使用gulp将TypeScript预编译为JavaScript,我有以下项目结构：

|_ grails-app
|_ frontend
  |_ angular
    |_ app
    |    |_ components
    |    |     |_ something
    |    |          |_ something.component.ts
    |    |          |_ something.component.html
    |    |_ model
    |    |_ test
    |    |_ app.module.ts
    |    |_ app.routing.ts
    |    |_ main.ts
    |_ assets
    |_ build
    |    |_ app
    |        |_ components
    |        |      |_ something
    |        |          |_ something.component.html
    |        |          |_ something.component.js
    |        |          |_ something.component.js.map
    |        |_      
    |        |_      
    |        |      
    |_ node_modules
    |_ gulpfile.js
    |_ karma.conf.js
    |_ karma-test-shim.js
    |_ systemjs.config
    |_
    |_
    |

但是,如果我假设html文件是预编译的,并从测试中删除命令.compileComponents(),我会收到以下错误：

Firefox 48.0.0 (Mac OS X 10.11.0)
Error: Cannot create the component SomethingComponent as it was not imported into the testing module!

如果我删除异步,我收到此错误：

Firefox 48.0.0 (Mac OS X 10.11.0)
Error: This test module uses the component SomethingComponent which is using a "templateUrl",but they were never compiled. Please call "TestBed.compileComponents" before your test.

在karma-test-shim.js中,我有：

System.config({
baseURL: '/base/',paths: {
    // paths serve as alias
    'npm:': 'node_modules/'
},map: {
    'app': '/base/build/app/','@angular/core': 'npm:@angular/core/bundles/core.umd.js','@angular/common': 'npm:@angular/common/bundles/common.umd.js','@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js','@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js','@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js','@angular/http': 'npm:@angular/http/bundles/http.umd.js','@angular/router': 'npm:@angular/router/bundles/router.umd.js','@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',// angular testing umd bundles
    '@angular/core/testing': 'npm:@angular/core/bundles/core-testing.umd.js','@angular/common/testing': 'npm:@angular/common/bundles/common-testing.umd.js','@angular/compiler/testing': 'npm:@angular/compiler/bundles/compiler-testing.umd.js','@angular/platform-browser/testing': 'npm:@angular/platform-browser/bundles/platform-browser-testing.umd.js','@angular/platform-browser-dynamic/testing': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic-testing.umd.js','@angular/http/testing': 'npm:@angular/http/bundles/http-testing.umd.js','@angular/router/testing': 'npm:@angular/router/bundles/router-testing.umd.js','@angular/forms/testing': 'npm:@angular/forms/bundles/forms-testing.umd.js',// other libraries
    'rxjs': 'npm:rxjs'
},packages: {
    'app': {
        defaultExtension: 'js'
    },'rxjs': {
        defaultExtension: 'js'
    }
}
});

我希望有人可以帮我弄明白,我在配置上做错了什么.
