ember 渲染 hbs 吞咽抛出错误 [英] ember render hbs swallowing thrown error

问题描述

我有一个简单的组件集成测试:

I have a simple component integration test:

test('it throws error my-custom-input is called', function(assert) {
    assert.throws(() => {
        this.render(hbs`{{my-custom-input}}`);
    }, /my-custom-input component error/, 'Error must have been thrown');
});

component.js 的源码如下:

Source code of component.js is like:

export default Ember.Component.extend({
    layout,
    init() {
        this._super(...arguments);
        throw 'my-custom-input component error';
    }
}

虽然我的 ember-cli 版本是 2.3.0，但测试通过了.但是，在我将 ember-cli 版本更新到 2.11.1 后，测试没有通过.错误是:

While my ember-cli version was 2.3.0, the test was passing. However, after I've updated my ember-cli version to 2.11.1, the test did not pass. The error was:

    actual: >
        false
    expected: >
        true

为什么 ember 渲染开始吞噬抛出的异常?

Why does ember render start to swallow the thrown exception?

推荐答案

好吧，我不太清楚为什么 Ember 社区决定打破测试的解释；但如果有人需要，这里是修复程序.

Well I am not quite sure why Ember community decided to break the test explained; but here is the fix if anyone needs it.

您需要通过<安装ember-qunit-assert-helpers

ember install ember-qunit-assert-helpers

您需要将 throws 异常的代码更改为 Ember.assert 并且在您的测试类中您只需要使用 assert.expectAssertion 而不是 assert.throws.

You need to change your code that throws an exception to Ember.assert and in your test class you just need to use assert.expectAssertion instead of assert.throws.
