Zombie.js pressButton Long Callback Delay [英] Zombie.js pressButton Long Callback Delay

问题描述

我一直试图通过使用一堆console.log来解决这个问题，但仍然无法弄清楚为什么这些加载时间太长。

I've been trying to figure this out by using a bunch of console.logs and still can't figure out why these load times are so long.

所以我在我的Mocha单元测试文件中的 beforeEach 中有以下代码。

So I have the following code in my beforeEach in my Mocha unit test file.

browser.fill('email', '[e-mail]');
browser.fill('password', 'testtest');
browser.pressButton('Login').then(function () {
    console.log("#100 - "+ new Date().getTime());
    done();
});

在这种情况下按下按钮会有一些重定向，最后会显示一个仪表板页面。在该html文件的底部，我有以下代码。

Pressing the button in this case will have a few redirects then finally display a dashboard page. At the bottom of that html file I have the following code.

<script>
    $(document).ready(function () {
        console.log("#200 - "+ new Date().getTime());
    });
</script>

所以在运行测试后如果我在＃100之后取值 减去 ＃200 之后的值总是大约5000-6000。因为＃200 总是在＃100 之前打印5-6秒。

So after running the tests if I take the value after #100 minus the value after #200 it's always about 5000-6000. Because #200 always gets printed before #100 by like 5-6 seconds.

我不明白为什么在加载页面后，Zombie.js需要额外的5-6秒才能调用该回调函数。

I don't understand why after loading the page it takes an additional 5-6 seconds about for Zombie.js to call that callback function.

Zombie.js在加载页面后是否有一些等待或延迟？还有什么可能导致页面加载和Zombie.js之间的5-6秒延迟调用该回调函数？

Does Zombie.js have some wait or delay that I'm missing after loading the page? What else could be causing this 5-6 second delay between the page loading and Zombie.js calling that callback function?

编辑我现在有同样的问题，但像50000ms。在我的所有测试中，这真的非常快。我仍然无法弄清楚为什么会发生这种情况。

EDIT I now have this same problem but with like a 50000ms. And that really adds up super quickly over all of my tests. I still can't figure out why this is happening.

如果我将 browser.debug（）添加到我的测试中，它会在最后打印以下内容。它还会打印很多其他内容，但这种情况很快就会发生。我认为以下可能是问题所在。只是不确定它为什么这样做或如何解决它。

If I add browser.debug() to my test it prints the following at the very end. It also prints a lot of other stuff but that happens overall pretty quickly. I think the following might be the problem. Just not sure why it's doing that or how to fix it.

zombie Fired setInterval every 5000ms +11ms
zombie Fired setInterval every 5000ms +5s
zombie Fired setInterval every 5000ms +5s
zombie Fired setInterval every 5000ms +5s
zombie Fired setInterval every 5000ms +5s
zombie Fired setInterval every 5000ms +5s
zombie Fired setInterval every 5000ms +5s
zombie Fired setInterval every 5000ms +5s
zombie Fired setInterval every 5000ms +5s
zombie Fired setInterval every 5000ms +5s
zombie Fired setInterval every 5000ms +5s

导致所有 zombie每隔5000ms触发setInterval的原因是什么以及如何修复它以使其不需要55000ms +？

What is causing all of the zombie Fired setInterval every 5000ms and how do I fix it to make it not take 55000ms+?

我还在单元测试开始时添加了以下代码。

I also added the following code at the beginning of the unit test.

browser.addListener("setInterval",function (a,b) {
    console.log("a: "+a);
    console.log("b: "+b);
});

打印每个 zombie Fired setInterval每5000ms + 5s 由于该监听器，它还会打印以下内容。

After printing each zombie Fired setInterval every 5000ms +5s it also prints the following because of that listener.

a: function (){var b,c,d;if(b=window.location.href,b!==h){try{d=JSON.stringify({action:"ping",sid:a.utils.getSessionID(),muid:a.utils.getMerchantID(),referrer:h,url:b,title:document.title}),e.contentWindow.postMessage(d,"*")}catch(f){c=f}return h=b}}
b: 5000

a 和 zombie Fired setInterval每隔5000毫米后，> b 相同。它在这11次之间根本没有变化。

a and b are the same after each one of those 11 zombie Fired setInterval every 5000ms. It doesn't change at all between those 11 times.

我认为这个功能在某种程度上会有所帮助，但我仍然不明白为什么会发生这种情况或如何修复它完全没有。

I thought that function would help in someway but I still don't understand why this is happening or how to fix it at all.

推荐答案

Zombie在触发回调之前加载所有资源并处理所有事件。不要使用 pressButton ，请尝试直接提交表单并使用等待并使用终结器回调，该回调将在每个事件后调用。这应该会告诉你导致延迟的原因：

Zombie loads all resources and processes all events before triggering the callback. Instead of using pressButton, try submitting the form directly and using wait with a terminator callback which will be called after each event. This should show you what's causing the delay:

browser.document.forms[0].submit();
browser.wait(function(){
   //called after each event
}, function() {
   //all events processed
});

来自API文档：

browser.wait（回调）

browser.wait（终结者，回调）

处理队列中的所有事件并在完成后调用回调。

Process all events in the queue and calls the callback when done.

您可以使用秒表单在处理所有
事件之前传递控件。终结符可以是数字，在这种情况下，处理许多事件
。它可以是函数，在每个事件之后调用;当函数返回值false时，
处理停止。

You can use the second form to pass control before processing all events. The terminator can be a number, in which case that many events are processed. It can be a function, which is called after each event; processing stops when the function returns the value false.
