I am working on creating an application on the beta version of Angular2, and when I run my test case, I accidentally get an error message:
The selector "# root0" does not match element errors.
Security Code:
@Component({ template: '', directives: [GroupBox, GroupBoxHeader] }) class TestComponent { } describe('group-box control', () => { it('should show the title', injectAsync([TestComponentBuilder], (tcb) => { return tcb.overrideTemplate(TestComponent, '<group-box><group-box-header>Title Content</group-box-header></group-box>') .createAsync(TestComponent).then( (fixture) => { fixture.detectChanges(); let compiled = fixture.debugElement.nativeElement; expect(compiled).toContainText('Title Content'); }); })); it('should show the body', injectAsync([TestComponentBuilder], (tcb) => { return tcb.overrideTemplate(TestComponent, '<group-box><group-box-header>Title Content</group-box-header>Body Content</group-box>') .createAsync(TestComponent).then( (fixture) => { fixture.detectChanges(); let compiled = fixture.debugElement.nativeElement; expect(compiled).toContainText('Body Content'); }); })); });
Im using Karma with Jasmine following the guidelines https://github.com/juliemr/ng2-test-seed
The following repository reproduces the error: https://github.com/cangosta/ng2_testing_controls
