Question

我们的项目成功编译，构建并可在浏览器中看到。这里没问题。

但是当我们尝试使用karma and jasmine运行测试用例时，我们会收到此错误。

FAILED TESTS:
 XXXXXXComponent
   :heavy_multiplication_x: Should Match Current Tab as 1

   Error: Template parse errors:

   Can't bind to 'dividerColor' since it isn't a known property of 'md-input'.
   1. If 'md-input' is an Angular component and it has 'dividerColor' input, then verify that it is part of this module.
   2. If 'md-input' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schemas' of this component to suppress this message.

                                           "):

我们已根据新的角度约定在app.module.ts中导入了所有这些模块。

import { FormsModule, ReactiveFormsModule } from '@angular/forms';
@NgModule({
  bootstrap: [ AppComponent ],
  declarations: [
    ...
  ],
  imports: [ // import Angular's modules
    ...
    BrowserModule,
    FormsModule,
    HttpModule,
    ReactiveFormsModule,
    ... ],
  providers: [ // expose our Services and Providers into Angular's dependency injection
    ENV_PROVIDERS,
    APP_PROVIDERS
  ],
  schemas: [
    CUSTOM_ELEMENTS_SCHEMA
  ]
})
export class AppModule {
  constructor() {}
}

我们已安装所有最新版本的软件包。

"karma": "^1.2.0",
"karma-chrome-launcher": "^2.0.0",
"karma-coverage": "^1.1.1",
"karma-jasmine": "^1.0.2",
"karma-remap-coverage": "^0.1.4",
"karma-sourcemap-loader": "^0.3.7",
"karma-webpack": "2.0.1",
"webpack": "2.2.0",
"webpack-dev-middleware": "^1.9.0",
"webpack-dev-server": "2.2.0",
"webpack-dll-bundles-plugin": "^1.0.0-beta.5",
"webpack-md5-hash": "~0.0.5",
"webpack-merge": "~2.4.0"

TestBed设置：

TestBed.configureTestingModule({
    imports: [ReactiveFormsModule, FormsModule],
    declarations: [ XXXXComponent ], // declare the test component
});

感谢您解决此问题的任何帮助。

您的错误是因为您需要在md-input-container标记内部使用dividerColor指令而不是md-input。

Karma无法识别角度指令
