Webdriver - 等待在Firefox中不工作 [英] Webdriver - waits not working in Firefox

问题描述

在我的应用程序中，我有一个显示在屏幕上的记录元素。所以在第一页上，会显示显示2100的1-10。这是该元素的CSS，它可以在所有浏览器中使用。

  span.GridPagingInfo 
  
 
 
当我改变页面时，那个元素的文本会改变。所以如果我去第二页，会显示显示2100的11-20。在继续我的测试之前，我正在等待文本改变。下面是我使用的代码 
 
 
  //验证元素的文本
 String actualText = driver.findElement（By .cssSelector（ span.GridPagingInfo））的getText（）; 
 Assert.assertEquals（actualtext，显示2100的1-10）; 
 //点击下一步按钮转到下一页
 driver.findElement（By.cssSelector（th.GridPaging button.ViewMore））。click（）; 
 //等待元素的文本改变
 WebDriverWait wait = new WebDriverWait（driver，30）; 
 wait.until（ExpectedConditions.textToBePresentInElementLocated（By.cssSelector（span.GridPagingInfo），Showing 2100 of 2100））; 
  
我也曾尝试过 
 
 
  wait.until（ExpectedConditions.invisibilityOfElementWithText（By.cssSelector（span.GridPagingInfo），display 1-10 of 2100））; 
  
当我尝试这个功能时，它可以在除Firefox以外的所有浏览器中使用。当我在Firefox中运行我的测试时，测试将会等待，并等待一个错误，说它找不到文本。当我观看测试时，应用程序进入下一页，元素在那里，我想要的文本在那里，但是Selenium说它找不到它。我试着回滚到之前版本的Firefox，但是没有帮助。

解决方案
我不知道为什么这样解决了这个问题，是我做的。我只是将超时从30更改为45，一切正常。在Firefox中，页面加载一秒钟，所以我不知道为什么它是在30之后超时。无论如何，改为45固定在Firefox的问题。  
In my application, I have an element for records displayed on the screen. So on the first page, it will say something like "displaying 1-10 of 2100". This is the CSS for that element, and it works in all browsers.
span.GridPagingInfo
In my application, which is in an iframe, I need to change pages and wait for the page to be loaded before continuing. The element that I previously mentioned is the last element on the page, so I am using that for my waits. Since its on the bottom, if it is displayed, then the information I need to continue my tests is loaded. 

When I am changing pages, the text of that element changes. So if I go to the 2nd page, it will say "displaying 11-20 of 2100". I am waiting for the text to change before continuing my tests. Below is the code I am using
//verify text of the element
  String actualText = driver.findElement(By.cssSelector("span.GridPagingInfo")).getText();
  Assert.assertEquals(actualtext, "displaying 1-10 of 2100");
//Go to next page by clicking the Next button
  driver.findElement(By.cssSelector("th.GridPaging button.ViewMore")).click();
//wait for text of the element to change
  WebDriverWait wait = new WebDriverWait(driver,30);
  wait.until(ExpectedConditions.textToBePresentInElementLocated(By.cssSelector("span.GridPagingInfo"), "displaying 11-20 of 2100"));
I have also tried
wait.until(ExpectedConditions.invisibilityOfElementWithText(By.cssSelector("span.GridPagingInfo"), "displaying 1-10 of 2100"));
When I try this, it works in every browser except Firefox. When I run my tests in Firefox, the test will time out on the wait with an error saying that it could not find the text. When I watch the test, the application goes to the next page, the element is there, the text I want is there, but Selenium says it cannot find it. I have tried rolling back to previous versions of Firefox, but that did not help. 


Firefox version - 33 
IE version - 11
IE Driver - 2.44
Chrome version - 39
Chrome Driver - 2.11
Selenium Server - 2.44.0.jar

解决方案
I have no idea why this fixed the issue, but here is what I did. I just changed the timeout from 30 to 45 and everything worked fine. In Firefox, the page loads in a second, so I don't know why it was timing out after 30. Anyway, changing to 45 fixed the issue in Firefox.
