Question

Discovered the synthetic characteristic @enterAnimation. Make sure to incorporate either "BrowserAnimationsModule" or "NoopAnimationsModule" within your Angular4 application

While testing my Angular4 application with Karma, I encountered the following error message:

Found the synthetic property @enterAnimation. Please include either "BrowserAnimationsModule" or "NoopAnimationsModule" in your application.

. However, I have already imported the module in app.module.ts.

        // animation module
        import { BrowserAnimationsModule } from '@angular/platform-browser/animations'; 
    ...
@NgModule({
    imports: [...
        BrowserAnimationsModule,
        ...
      ],

In addition, within my component:

 import { Component, OnInit } from '@angular/core';
    import {
      trigger,
      state,
      style,
      animate,
      transition
    } from '@angular/animations';

    @Component({
      selector: 'app-about',
      animations: [
        trigger(
          'enterAnimation', [
            transition(':enter', [
              style({ transform: 'translateX(100%)', opacity: 0 }),
              animate('500ms', style({ transform: 'translateX(0)', opacity: 1 }))
            ]),
            transition(':leave', [
              style({ transform: 'translateX(0)', opacity: 1 }),
              animate('500ms', style({ transform: 'translateX(100%)', opacity: 0 }))
            ])
          ]
        ),
        trigger(
          'enterAnimationVetically', [
            transition(':enter', [
              style({ transform: 'translateY(100%)', opacity: 0 }),
              animate('500ms', style({ transform: 'translateY(0)', opacity: 1 }))
            ]),
            transition(':leave', [
              style({ transform: 'translateY(0)', opacity: 1 }),
              animate('500ms', style({ transform: 'translateY(100%)', opacity: 0 }))
            ])]
        )
      ],
...

Interestingly, the application functions perfectly when using ng serve, yet the error appears with Karma testing.

Dear future readers: If you happen to encounter this error, it may be due to the omission of

animations: [ <yourAnimationMethod()> ]

within your @Component TypeScript file.

This issue arises when using [@yourAnimationMethod] in the HTML template for Angular animations. More information can be found here.

To solve the issue in my Angular 6 application, I successfully implemented a solution by including the following lines of code in my component's .spec.ts file:

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

Furthermore, I made sure to add BrowserAnimationsModule to the imports section of the TestBed.configureTestingModule within the same component's .spec.ts file.

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [ LinkedSitesComponent ], imports: [ BrowserAnimationsModule ],
    })
    .compileComponents();
  }));

If encountering this issue within Storybook, ensure to include the BrowserAnimationsModule in the moduleMetadata of your story.
For example,

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


export const Primary = () => ({
  template: `
   <div style="width: 720px">
    <view-list [data]="data"></view-list>
   </div>
   `,
  moduleMetadata: {
    imports: [AppModule, BrowserAnimationsModule],
  },
  props: {
    data: SOME_DATA_CONSTANT,
  },
});

PS: In Angular projects, the above-mentioned solutions have been proven effective.

While conducting unit testing, if you encounter this error, consider importing the utility module NoopAnimationsModule into your spec file. This module simulates animations without actually animating.

import { NoopAnimationsModule } from '@angular/platform-browser/animations';

If you have already added BrowserAnimationsModule but the animations are still not working, you will need to include the animations attribute in your @component as shown below:

@Component({
  selector: 'app-orders',
  templateUrl: './orders.component.html',
  styleUrls: ['./orders.component.scss'],
  animations: [
    trigger('detailExpand', [
      state('collapsed', style({
        height: '0px',
        minHeight: '0'
      })),
      state('expanded', style({
        height: '*'
      })),
      transition('expanded <=> collapsed', animate('225ms cubic-bezier(0.4, 0.0, 0.2, 1)')),
    ]),
  ],
})

To enhance the functionality of my component (users-component.ts), I simply included this line within it:

@Component({
animations: [appModuleAnimation()],
})

Make sure to import the necessary module in app.component.ts or wherever you manage your module imports.

// animation module
import { BrowserAnimationsModule } from '@angular/platform-browser/animations'; 

@NgModule({
imports: [
BrowserAnimationsModule,
],
})
