我正在安装' ember-moment'帮助,然后我在组件中使用它。一旦我这样做,那些组件'测试打破说什么都没有:

以下是测试本身的代码,它只是自动生成:
import {
moduleForComponent,
test
} from 'ember-qunit';
moduleForComponent('event-card', {
// Specify the other units that are required for this test
// needs: ['component:foo', 'helper:bar']
});
test('it renders', function(assert) {
assert.expect(2);
// Creates the component instance
var component = this.subject();
assert.equal(component._state, 'preRender');
// Renders the component to the page
this.render();
assert.equal(component._state, 'inDOM');
});
我尝试了一些方法,将这个帮助程序作为依赖项添加到测试中,如needs: ['helper:moment']
,并将其初始化程序签名添加到moduleForComponent函数的参数中,但没有任何效果,我无法做到找到有关它的任何信息。非常感谢帮助。

修改:根据此PR,您应该能够指定{ integration: true }
将现有的单元测试转换为集成测试,从而无需needs:
1}}。
moduleForComponent('post', { integration: true });
可在此处找到更多背景信息:https://github.com/rwjblue/ember-qunit/issues/108。从本质上讲,集成标志会禁用测试的隔离容器,以便它可以访问应用程序的解析器。
注意:需要ember-qunit@0.2.11.
旧答案:看一下这个PR:https://github.com/switchfly/ember-test-helpers/pull/21,它会添加moduleForIntegration
。这是相关位:
这增加了一种新的测试模块,填补了当前的空白 一组可能的测试。到目前为止,我们有:
•有利于单独测试算法正确性的单元测试。
•适用于完整测试的验收测试 应用
但我们缺少集成测试小于的单位的能力 整个应用程序。这个PR添加了一个新的TestModuleForIntegration 允许您使用模板驱动集成测试。我想是的 通常是测试Ember组件而不是单元的更合适的方法 测试,因为有趣的组件往往具有丰富的依赖性 其他组件。
您可以在liquid-fire tests中看到它正在使用:
/* global sinon */
import Ember from "ember";
import moduleForIntegration from "../../helpers/module-for-integration";
import { test } from "ember-qunit";
moduleForIntegration('Integration: liquid-if');
test('it should render', function(assert) {
this.set('person', 'Tom');
this.render(`
{{#liquid-if isReady}}
{{person}} is ready
{{else}}
{{person}} is not ready
{{/liquid-if}}
`); // }}`)
assert.equal(this.$().text().trim(), 'Tom is not ready');
this.set('person', 'Yehuda');
assert.equal(this.$().text().trim(), 'Yehuda is not ready');
this.set('isReady', true);
assert.equal(this.$().text().trim(), 'Yehuda is ready');
});

所以这就是最终的工作:
import {
moduleForComponent,
test
} from 'ember-qunit';
import Ember from 'ember';
import { initialize } from '../../../../../initializers/ember-moment';
moduleForComponent('event-card', {
// Specify the other units that are required for this test
// needs: ['helper:moment'],
setup: function (container) {
Ember.run(function () {
// these two arguments are not used
// but probably still good to pass them in
// in the event we leverage them in the future
initialize(container);
});
}
});
test('it renders', function (assert) {
assert.expect(2);
// Creates the component instance
var component = this.subject();
assert.equal(component._state, 'preRender');
// Renders the component to the page
this.render();
assert.equal(component._state, 'inDOM');
});

你是否看到注释掉的那行:
// needs: ['component:foo', 'helper:bar']
您需要取消注释并将其读取:
needs: ['helper:moment']
如果您的moment
