如何测试 FlexUnit 4 中的事件序列？

我有一个组件，在创建时会分派两个事件来填充数据字段。这些事件应该保持独立，因为它们在其他地方用于不同的操作。

我想编写一个异步 Flexunit 测试来确认这些事件都已发送。问题是，它们都是同一事件的变体。

这是代码：

组件：

internal function creationComplete(): void {
    new GetDataEvent(GetDataEvent.GET_DATA, "aField").dispatch();
    new GetDataEvent(GetDataEvent.GET_DATA, "anotherField").dispatch();
}

测试（据我所知）：

[Test(async)]
public function creationCompleteShouldLoadRequiredData(): void {
    Async.handleEvent(this, new CairngormEventDispatcherAdapter(), GetDataEvent.GET_DATA,
            function(event: Event, ...rest): void {
                assertThat(event, hasProperty("data", hasProperty("field", "aField")));
            });
    fixture.creationComplete();
}

问题是，这仅测试第一个获取数据事件是否已调度，更糟糕的是，取决于事件调度的顺序。我如何测试这两个事件最终是否通过此方法发送出去，无论它们的顺序如何？

I have a component that, on creation, dispatches two events to populate data fields. The events should remain separate because they're used elsewhere for distinct actions.

I want to write an asynchronous flexunit test to confirm that these events are both sent. The problem is, they're both variants of the same event.

Here's the code:

Component:

internal function creationComplete(): void {
    new GetDataEvent(GetDataEvent.GET_DATA, "aField").dispatch();
    new GetDataEvent(GetDataEvent.GET_DATA, "anotherField").dispatch();
}

Test (as far as I have it):

[Test(async)]
public function creationCompleteShouldLoadRequiredData(): void {
    Async.handleEvent(this, new CairngormEventDispatcherAdapter(), GetDataEvent.GET_DATA,
            function(event: Event, ...rest): void {
                assertThat(event, hasProperty("data", hasProperty("field", "aField")));
            });
    fixture.creationComplete();
}

The thing is, this only tests that the first get data event is dispatched, and worse, depends on the order of event dispatch. How can I test that both of these events are eventually sent out by this method, regardless of their order?
