An Angular 2 module for mocking components.
npm install ng2-mock-componentA very simple Angular 2 module for mocking components in unit tests.
``
npm install --save-dev ng2-mock-component
Just specify the selector of the component you wish to mock (along with whatever otherMockComponent
metadata properties
you like), and will supply that component with an empty template (unless you provide
a template string, in which case, it'll use that instead).
`
import { TestBed } from '@angular/core/testing';
import { By } from '@angular/platform-browser';
import { MyComponent } from './src/my.component';
import { MockComponent } from 'ng2-mock-component';
describe('MyComponent', () => {
let fixture, element;
beforeEach(() => {
TestBed.configureTestingModule({
declarations: [
MyComponent,
MockComponent({ selector: 'my-subcomponent' })
]
});
fixture = TestBed.createComponent(MyComponent);
element = fixture.debugElement;
});
it('works', () => {
fixture.detectChanges();
expect(element.query(By.css('my-subcomponent'))).not.toBeNull();
});
});
