  14 |   it('should create the module', () => {
> 15 |     const module: MyModule = TestBed.inject(MyModule);
     |                                                         ^
  16 |     expect(module).toBeTruthy();
  17 |   });
  18 | });

Provide detailed reproduction steps (if any)

The module MyModule:

@NgModule({ imports: [ CommonUtilModule ], declarations: [], exports: [], }) export class MyModule {}

The CommonUtilModule:

@NgModule({ imports: [CommonModule, CKEditorModule], declarations: [], exports: [], }) export class CommonUtilModule{}

Writing a simple test:

import { TestBed } from '@angular/core/testing';
import { MyModule } from './my-module.module';

describe('MyModule', () => {
beforeEach(async () => {
await TestBed.configureTestingModule({
imports: [MyModule],
})
.compileComponents();
});

it('should create the module', () => {
const module: MyModule = TestBed.inject(MyModule);
expect(module).toBeTruthy();
});
});

When running the test, it fails and I get this error:

Unexpected value 'CKEditorModule' imported by the module 'CommonUtilModule'. Please add an @NgModule annotation.

Interesting thing, if I use npm i, to isntall dependencies, there is no error and the test pass. but using pnpm i, I get this error.

this is a screen of the not working (pnpm installed) ckeditorModule:

and the screen using npm i:

on the screenshots i'm using 2.3.0 version, however I get the same behaviour using the latest

Expected result

it should works for unit test using pnpm

Actual result

the test is not passing using pnpm

Could you provide the version of Angular you are using and check if the same is used when installed via npm and pnpm?

The CKEditor 4 Angular integration does not support Angular 12+ yet, please see https://github.com/ckeditor/ckeditor4-angular/issues/244#issuecomment-1580926181 for more details.

As the issue seems to be connected with the Angular 12+ support, I'm going to close it. However, if the issue wouldn't be resolved by the new version of the package, feel free to ping me and I'll reopen the issue.
