You need to get the instance of the component in order to call the ngOnDestroy() method. I think the following will work:10import { MockBuilder, MockRender, ngMocks } from 'ng-mocks';11describe('test', () => {12  beforeEach(() => MockBuilder().keep(MyComponent));13  it('should work', () => {14    const fixture = MockRender(MyComponent);15    const component = ngMocks.findInstance(MyComponent);16    ngMocks.finally(component);17  });18});19@josephsundstrom I'm not sure what's going on. I just tried it on my end and it worked. I'm using Angular 8.2.14 and ng-mocks 9.0.0 as well. I have a component with a ngOnDestroy() method that just logs to the console. The test is as follows:20describe('test', () => {21  beforeEach(() => MockBuilder().keep(MyComponent));22  it('should work', () => {23    const fixture = MockRender(MyComponent);24    const component = ngMocks.findInstance(MyComponent);25    ngMocks.finally(component);26  });27});
