Тестирование - Периодическая ошибка: «Не удалось: селектор« # root0 »не соответствует никаким элементам»

Я работаю над созданием приложения на бета-версии Angular2, и когда я запускаю свой тестовый пример, я случайно получаю ошибку:Тестирование - Периодическая ошибка: «Не удалось: селектор« # root0 »не соответствует никаким элементам»

The selector "#root0" did not match any elements' error.

тест код:

@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 используя карму с жасмином, следуя директивам https://github.com/juliemr/ng2-test-seed

следующая репозитария воспроизводит ошибку: https://github.com/cangosta/ng2_testing_controls

Я попробую. Я не использую TS, я использую ES6 + Traceur. Я создал репо, где вы можете легко воспроизвести ошибку: https://github.com/cangosta/ng2_testing_controls – cangosta

Gunter, я обновил репозиторий с упрощенной версией – cangosta

. [Ошибка с TestComponentBuilder] (https://github.com/angular/angular/issues/5662) с templateUrl. Временное исправление для него заключается в использовании '.overrideTemplate (TestComponent,'

')', как вы doiing. НО, вы переопределяете компонент TestComponent и NOT GroupBox, который также имеет 'templateUrl:../Group-box.html'' ... Я верю, что это вызывает ошибку, но, к сожалению, я не знаю, как ее исправить - Я тестировал только изолированные компоненты ... – Sasxa

Это фиксируется в угловых 2.0.0-beta.3

См https://github.com/angular/angular/issues/6483#issuecomment-179557485 для более подробной информации

Basically, what I had to do:

Manually add typings for jasmine with tsd install jasmine -so and add ///<reference... in the test files;

Add this in my imports:

import {setBaseTestProviders} from 'angular2/testing'; 

import { 
    TEST_BROWSER_PLATFORM_PROVIDERS, 
    TEST_BROWSER_APPLICATION_PROVIDERS 
} from 'angular2/platform/testing/browser';

Add this before my Component tests:

setBaseTestProviders(TEST_BROWSER_PLATFORM_PROVIDERS, TEST_BROWSER_APPLICATION_PROVIDERS);
