C＃和断点 - 我们在这里有什么魔术师？ [英] C# and breakpoints - do we have any magician in here?

问题描述

我有这样的：

public static void ByLinkText(string text)
{
    for (var i = 0; i < 50; i++)
    {
        try
        {
            Setup.Driver.FindElement(By.LinkText(text)).Click();
            return;
        }
        catch (Exception)
        {
        }
    }
}

（中间的奇怪的代码是硒 - 让刚刚跳过，这是不是这里的情况）

(The weird code in the middle is selenium - lets just skip that, it's not the case here)

好吧，所以我有这个 ByLinkText（）方法，你不要在这里看到的，就是我重复此方法无限直到这中间啄能够正确执行，然后打的<$ 。C $ C>收益之后

Okay, so I have this ByLinkText() method, what you don't see here, is that I repeat this method infinitely until this middle thingy will execute correctly and then hit that return after.

所以：这中间代码不正确执行，我想知道为什么，所以我是什么在做什么？我把一个断点在catch部分。发生什么事？没有（和 ByLinkText（）仍保持持续无限！）。

So: This middle code is NOT executing correctly, and I want to know why, so what am I doing? I put a breakpoint in the catch section. What is happening? Nothing (and ByLinkText() still keeps going infinitely!).

现在，你能告诉我：嘿！这中间代码只是不扔任何东西，但哦甜蜜的祝福......这中间的代码可以做两件事情：我要么扔东西，或做它喜欢它应该（的 prove1 和的 prove2 ）。

Now, you would tell me "Hey! That middle code is just not throwing anything!", but oh sweet wishes... That middle code can do two things: either throw something at me, or do it like it should (prove1 and prove2).

因此，最后，这是怎么一回事呢？关于断点。当我把我的断点上收益（神奇的代码之后！）的代码执行正确！如何在programical世界是可能的，该断点修理我的应用程序！？

So finally, what is this all about? About breakpoints. As soon as I put my breakpoint on that return (right after magical code!) that code executes properly! HOW in the programical world is that possible, that breakpoint repairs my application!?

推荐答案

我觉得这更多的是与硒比你似乎相信。看一看寻找元素隐性和显性的等待。

I think this has more to do with selenium than you seem to believe. Have a look at implicit and explicit waits for finding the element.

HTTP：//docs.seleniumhq。组织/文档/ 04_webdriver_advanced.jsp

试试另一件事情是保存IWebElement导致到一个临时变种，穿上小觉，然后单击它。有时浏览器的用户界面不能处理的命令一样快，硒发出它们。

Another thing to try is to save the IWebElement result into a temp var, put on small sleep and then click it. Sometimes the browser ui can't handle the commands as fast as selenium issues them.

var el = Setup.Driver.FindElement(By.LinkText(text));
Thread.Sleep(750);
el.Click();
