title: How do I Set the State of NGRX Store in StoryBook & Angular tests?
body: <p>Does anyone know how or have links for using StoryBook &amp; Angular with NGRX Store ?</p>
  <p>I have followed the StoryBook tutorial but still cannot figure out how to use StoryBook with NGRX Store.
  I can use StoryBook with Angular Dumb Components fine.
  I need to be able to set the NGRX Store State for the stories of my Nested components.</p>
  <p>eg.
  In my <strong>SmartComponent</strong> I have:</p>
  <p><code>this.accountDebtor$ = this.coreStore.select( coreSelector.selectAccountDebtorState );</code></p>
  <p>In the <strong>Story</strong> I have:</p>
  <pre><code>export const LoadedAccountPanel = (args) =&gt; ({
   component: AccountComponent,
   props: args,
  });
  LoadedAccountPanel.args = {
   panelData: {},
   accountDebtor$: &lt;-- How do I set the State so this gets set using the store ???,
  };
  </code></pre>
