Hi @mdv27, thanks for the report. Please provide a repo which fails the error. |
|
If it's easier you can upload an archive with the project and node_modules right here in your comment. |
|
@satanTime Created repo from scratch and it does fail with same error. Let me know if more details are required. |
|
Thanks! checking it! |
|
So, the problem comes from |

That's so quick! 😮 👏 May I know how did you find the root cause? |

Basically I removed everything from your component, the test was failing, then I started to remove module by module and found out this dependency. The final test is: import {MockBuilder, MockRender} from 'ng-mocks';
import {TestBed} from "@angular/core/testing";
import {NgModule} from '@angular/core';
import {InputsModule} from '@progress/kendo-angular-inputs';
import {Component} from '@angular/core';
@Component({
selector: 'app-header',
template: '',
})
class HeaderComponent {}
@NgModule({
declarations: [HeaderComponent],
imports: [
InputsModule,
],
})
class AppModule {}
describe('HeaderComponent', () => {
describe('ng-mocks', () => {
beforeEach(() => MockBuilder(HeaderComponent, AppModule));
it('should create component', () => {
const fixture = MockRender(HeaderComponent, {});
const component = fixture.point.componentInstance;
expect(component).toBeDefined();
});
});
describe('TestBed', () => {
beforeEach(() => {
return TestBed.configureTestingModule({
imports: [AppModule],
}).compileComponents();
});
it('should create component', () => {
const fixture = TestBed.createComponent(HeaderComponent);
fixture.detectChanges();
const component = fixture.componentInstance;
expect(component).toBeDefined();
});
});
}); |

Ideally if module/dependency is mocked/stubbed, test should not trigger/run the dependency code, I assume this is not honored with |
|
I think there is a problem how the mock of a dependency has been defined, so when Angular is creating a TestBed env, it stumbles over it. |
|
So. Some of declarations of Now |
fix(core): generates compatible function names #3274
|
v14.1.3 has been released and contains a fix for the issue. Feel free to reopen the issue or to submit a new one if you meet any problems. |

This change is working for me. Thank you @satanTime 👏 |
