等待所有JDA RestActions [英] await all JDA RestActions

问题描述

我想为JDA Discord Bots创建一个(功能)测试系统.

I want to create a (feature) testing system for JDA Discord Bots.

为此，我需要等待直到当前队列中的所有消息都已发送(消息已通过 RestAction#queue 发送)并测试是否有消息.

For this, I need to wait until all messages in the current queue are sent(messages are sent with RestAction#queue) and test if there is the message.

是否有一种方法可以等待所有排队的 RestAction ，还是应该以指数方式等待(例如，等待0.5秒，等待1秒，等待2秒并测试消息是否存在)

Is there a way to await all queued RestActions or should I wait exponentially (e.g. wait 0.5 seconds, wait 1 second, wait 2 seconds and test if the message exists)

[注意]我不想在生产代码中将 queue 更改为 submit 并将其发送到测试.

[Note] I don't want to change the queue to submit in my production code and send it to the test.

推荐答案

理想情况下，测试系统根本不应该与Internet交互.但是，要回答您的问题，您可以使用

Ideally a testing system shouldn't interact with the internet at all. However, to answer your question you can wait for rest actions by using the promise returned by submit instead of using queue.

List<CompletableFuture<?>> list = new ArrayList<>();

list.add(action1.submit());
list.add(action2.submit());
...

CompletableFuture<Void> merged = CompletableFuture.allOf(list.toArray(new CompletableFuture[0]));

merged.whenComplete((v, error) -> {
    if (error != null) error.printStackTrace();
    else System.out.println("All futures completed successfully");
});
