Issue: Failed to Render: Error encountered during parsing of template: Element 'mat-checkbox' is not recognized as a valid element

For the purpose of testing my component, I wrote the following code snippet:

describe('Component: TestComponent', () => {
        let component: TestComponent;
        let fixture: ComponentFixture<TestComponent>;

        beforeEach(() => {
            TestBed.configureTestingModule({
                declarations: [TestComponent]
            });

            fixture = TestBed.createComponent(TestComponent);
            component = fixture.componentInstance;
        });
    });
    

Upon running ng test, an error is displayed as follows:

Failed: Template parse errors:
    'mat-checkbox' is not a known element...
    

I have verified my module.ts file and it seems to be correct. Additionally, I added the necessary import statement:

import {MatCheckboxModule} from '@angular/material/checkbox';
    

Despite all this, the error persists. Can anyone identify the issue in my code?

Answer №1

To successfully configure your Angular application, make sure to include the imports array before the declarations section. Follow these steps:

First, insert the following line of code:

import { MatCheckboxModule } from '@angular/material/checkbox';

Next, update the imports array as shown below:

TestBed.configureTestingModule({
   imports: [
        MatCheckboxModule
   ],
   declarations: [AddAlarmsFormComponent]
})

Answer №2

Awesome!

It seems like you may have missed importing the MatCheckboxModule in your spec.ts file or forgot to include it in the "imports" section of your ngModule declaration.

Would you mind giving it a try and letting me know if that resolves the issue?
