如何将 Storybook 与使用 [routerLink] (Angular) 的组件一起使用？

Question

我正在使用 Angular 11.0.5 和 Storybook 6.1.14 以及以下组件：

import { Component, HostBinding, Input } from '@angular/core';

@Component({
    selector: 'ui-navigation-item',
    template: `
        <a [ngClass]="{ 'no-decorations': !decorations }" [routerLink]="link">
            instead of ng-content
        </a>
    `,
    styleUrls: ['./navigation-item.component.scss'],
})
export class NavigationItemComponent {
    @Input()
    link!: (string | null)[] | null;
    
    @Input()
    decorations:boolean = true;
    
    @HostBinding('class')
    @Input()
    variant: 'regular' | 'reduced' = 'regular';
}

现在，当我尝试将它添加到 Storybook 时：

import { RouterModule } from '@angular/router';
import { Meta } from '@storybook/angular';
import { NavigationItemComponent } from './navigation-item.component';

export default {
    title: 'Navigation Item',
    component: NavigationItemComponent,
    moduleMetadata: {
        imports: [RouterModule],
    },
} as Meta;

export const Primay = () => ({
    component: NavigationItemComponent,
    props: {
        link: ['/'],
    },
});

我会得到这个错误：

        <a [ngClass]="{ 'no-decorations': !decorations }" [ERROR ->][routerLink]="link">

如何在 Storybook 中使用 [routerLink]？

PS: Whosebug 告诉我添加更多细节，但我不知道我还应该写什么。我搜索并偶然发现了一些问题，但它们都没有解决问题。我很确定我漏掉了一件小事，但我还想不通。

Answer 1

故事中没有导入 RouterModule，而是导入 RouterTestingModule

Answer 2

在元数据的 decorators 中指定模块导入：

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

export default {
    title: 'Navigation Item',
    component: NavigationItemComponent,
    decorators: [
        moduleMetadata({
            declarations: [NavigationItemComponent],
            imports: [RouterTestingModule],
        }),
    ],
} as Meta;
