我写了这个,@angular-redux/store想知道是否已经存在解决方案。

这是一个回顾,可以让您免于阅读链接:

到目前为止,使用 Angular 和 Storybook 效果很好。但是,在某些情况下,我的组件依赖于 @select()。如何让我的故事中的组件使用模拟的可观察对象或数据点?

这是我的示例代码:

import { storiesOf, moduleMetadata } from '@storybook/angular';

import { CommonModule } from '@angular/common';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

// Modules
... custom modules ...


// Components
...myAppComponents...
import { MyParticularComponent as component } from './my-particular.component';


// Mock Data
... mock json data...

const props = { ...mockData... };

storiesOf('This Particular Component', module)
  .addDecorator(
    moduleMetadata({
      declarations: [component, ...other components...],
      imports: [
        CommonModule,
        BrowserAnimationsModule,
        ...custom modules...
      ],
      schemas: [],
      providers: []
    })
  )
  .add('Some View of the Component', () => ({
    component,
    props
  }));

我的组件有:

@Input()
someInput: string;

@select()
stateValue$: Observable<SomeData>;

propOne;
propTwo;

ngOnInit() {
    this.stateValue$.subscribe(data => {
      const { propOne, propTwo } = data;
      this.propOne = propOne;
      this.propTwo = propTwo;
    });
  }

首先,我为我的组件创建道具。如果任何东西都有@select装饰器,那么它需要属于一个'@angular-redux::substore::instance::selections'属性。开始了:

const createProps = {

   const stateValue: DataStruct = {...};

   // Create the Observable.  Need .next and .complete for subscribe.
   const stateValue$: Subject<DataStruct> = MockNgRedux.getSelectorStub('stateValue');
   stateValue$.next(stateValue);
   stateValue$.complete();

   return {
      someInput: 'Hello World!',
      '@angular-redux::substore::instance::selections': {
           stateValue$
       }
   }
}


...
.add('Some View of the Component', () => ({
    component,
    props: createProps()
}));
