超时问题可以是browser.sleep（）和browser.waitForAngular的结果吗？

本文介绍了超时问题可以是browser.sleep（）和browser.waitForAngular的结果吗？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在量角器脚本中，我总是遇到超时问题，即使我把一个大的超时的茉莉花间隔， allscripttimeout ...
在某些地方我不得不等到元素出现在主页中，直到网址完全加载为止。

In protractor scripts i'm always having problem of time out, even if i put a big time out jasmine interval, allscripttimeout... And in some places i'm obliged to wait until element are present like in home page until the url is totally loaded.

超时问题可以是

browser.sleep（time_ms）;

的结果browser.waitForAngular（）;

如果是这样，我该如何解决这个问题？

If so, how can i fix this problem ?

谢谢，

推荐答案

是的，它们可能是 - browser.sleep（）只有在睡眠时间超过Jasmine超时间隔（默认为30秒）时才会超时。

Yes they could be -- browser.sleep() would only timeout if you had it sleep longer than your Jasmine timeout interval (default is 30 seconds).

browser.waitForAngular（）会自动应用于Protractor的每个webDriver动作，因此您不需要调用它。如果这个时间已经结束，那么你的应用程序仍在同步。

browser.waitForAngular() is automatically applied to every webDriver action by Protractor so you shouldn't need to call it. If this time's out then your app is still synchronizing something.

这两个都会导致 A Jasmine规范超时。重置WebDriver控制流。跟随错误：超时 - 在jasmine.DEFAULT_TIMEOUT_INTERVAL指定的超时时间内未调用异步回调。如果耗时太长。

Both of these would result in A Jasmine spec timed out. Resetting the WebDriver Control Flow. following by Error: Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL. if it takes too long.

我不肯定你会怎么解决它 - 你有很多关于超时的问题（有充分的理由），但此时我认为你需要使用 browser.ignoreSynchronization = true; 并将您的应用视为非Angular，如果您遇到这么多超时问题。有些事情阻止了同步完成。

I'm not positive how you would fix it - you've had a lot of questions about timeouts (for good reason), but at this point I think you need to use browser.ignoreSynchronization = true; and treat your app as non-Angular if you're having this many timeout issues. Something is preventing synchronization from finishing.

通过扩展Protractor的功能，可以在非Angular应用程序上无缝创建和执行几种辅助方法，以避免显式 browser.sleep（）的。例如，下面的代码暂停测试执行，直到 isPresent 返回true（或者直到超过 timeout 失败我指定）

There are several helper methods that you can create and execute seamlessly on non-Angular apps by extending Protractor's functions to avoid explicit browser.sleep()'s . For example, the below code pauses test execution until isPresent returns true (or until a failure by exceeding the timeout I specified)

Util.prototype.waitForElementPresent = function (el, time) {
    var timeout = time || 0,

    return browser.wait(function() {
        return el.isPresent();
    }, timeout)
};
