Я установил Ember 2.12 и создал новый проект с компонентом и тестом, чтобы убедиться, что он выдает ошибку, если не указан требуемый атрибут. Я не могу пройти этот тест.
dummy-component.hbs
{{value}}
{{yield}}
dummy-component.js
import Ember from 'ember';
export default Ember.Component.extend({
value: Ember.computed(() => {
Ember.assert("Someone forgot to provide a required value attribute");
})
});
фиктивный компонент-test.js
import { moduleForComponent, test } from 'ember-qunit';
import hbs from 'htmlbars-inline-precompile';
moduleForComponent('dummy-component', 'Integration | Component | dummy component', {
integration: true
});
test('it throws', function(assert) {
assert.throws(() => {
this.render(hbs`{{dummy-component}}`);
}, 'Error: Assertion Failed: Someone forgot to provide a required value attribute');
});
Тест не пройден со следующим:
