在Storybook中使用@ angular-redux/store测试Angular [英] Testing Angular with @angular-redux/store in Storybook
问题描述
我在 @ angular-redux/store
上写了这个,想知道是否已经存在解决方案.
I wrote this up on @angular-redux/store
and was wondering if a solution already existed.

到目前为止,使用Angular和Storybook的效果很好.但是,在某些情况下,我的组件依赖于@select().如何告诉故事中的组件使用模拟的可观察点或数据点?
Using Angular and Storybook has worked out well so far. However, I have cases where my component is dependent upon @select(). How can I tell the component in my story to use a mocked observable or data point?
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;
});
}
推荐答案
首先,我为组件创建道具.如果任何东西都有 @select
装饰器,则它必须属于'@ angular-redux :: substore :: instance :: selections'
属性.我们开始:
First, I create props for my component. If anything has an @select
decorator, then it needs to belong in an '@angular-redux::substore::instance::selections'
property. Here we go:
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()
}));
