title: Ng Test - Can't bind to 'value' since it isn't a known property of 'mat-select'
body: <p>I have an Angular6 application using Material Design. When running 'ng test', I get the following error:</p>
  
  <blockquote>
    <p>Failed: Template parse errors: Can't bind to 'value' since it isn't a known property of 'mat-select'.</p>
  </blockquote>
  
  <p>I have included MatSelectModule in my imports and exports. It works fine in the application but fails during testing.</p>
  
  <p>material-design.module.ts</p>
  
  <pre><code>import { NgModule } from '@angular/core';
  import { CommonModule } from '@angular/common';
  
  import { MatFormFieldModule, MatInputModule, MatSelectModule} from '@angular/material';
  
  @NgModule({
    imports: [MatFormFieldModule, MatInputModule, MatSelectModule],
    exports: [MatFormFieldModule, MatInputModule, MatSelectModule],
  })
  export class MaterialDesignModule { }
  </code></pre>
  
  <p><em>Select example:</em></p>
  
  <pre><code>&lt;mat-form-field class='select_buttons'&gt;
    &lt;mat-select (selectionChange)='typeSelection_changed($event)' [(value)]='type'&gt;
      &lt;mat-option *ngFor="let type of types" [value]="type"&gt; {{type.name}}&lt;/mat-option&gt;
    &lt;/mat-select&gt;
  &lt;/mat-form-field&gt;
  </code></pre>
