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：

  test（'it throws error my-custom-input is called' function（assert）{
 assert.throws（（）=> {
 this.render（hbs` {{my-custom-input}}`）; 
}，/ my-自定义输入组件错误/，'错误必须被抛出'）; 
}）; 
  

component.js的源代码如下：

导出默认值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，但测试已经过去了，但是在将我的ember-cli版本更新到2.11.1之后，测试没有通过，错误是：

 实际：> 
 false 
期望：> 
 true 
  

为什么ember渲染开始吞下抛出的异常？

解决方案我不太清楚为什么Ember社区决定打破测试解释;但是如果有人需要，这里是修复。

你需要安装 ember-qunit-as sert-helpers 通过

  ember install ember-qunit-assert-helpers 
  

您需要将代码 throws 将一个例外更改为 Ember.assert 并且在你的测试类中你只需要使用 assert.expectAssertion 而不是 assert.throws 。

答案是从github问题在以下地址。

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');
});

Source code of component.js is like:

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

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

Why does ember render start to swallow the thrown exception?

解决方案

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

You need to install ember-qunit-assert-helpers via

ember install ember-qunit-assert-helpers

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.
