【问题描述】:
我安装了 Ember 2.12 并创建了带有组件和测试的新项目,以确保在未提供所需属性时它会引发错误。我不能让这个测试通过。
虚拟组件.hbs
{{value}}
{{yield}}
虚拟组件.js
import Ember from 'ember';
export default Ember.Component.extend({
value: Ember.computed(() => {
Ember.assert("Someone forgot to provide a required value attribute");
})
});
dummy-component-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');
});
测试失败并显示以下内容:
