Question

我有一个Selenium网络驱动程序脚本，它只访问一个web元素（文本框）并将其值设置为某个值。

我使用的是ChutzPath，因为它在后端使用了PhantomJS浏览器。

但每次执行脚本时，都会显示以下错误。

T
Result Message: 
Test method Test_Project_with_Selenium.UnitTest1.BrowseTheWeb threw exception:

Answer 1

不确定这是否是这种情况，因为问题不是很具体，但我遇到的一件事是PhantomJS 1.9.7需要在该位置使用HTTP方案。

因此，如果您要导航localhost:42982/element，则应指定您要导航到http://localhost:42982/element的驱动程序。

关闭袖口，你可能遇到Selenium查询页面后加载元素的问题，你可以使用waitfor.js

https://github.com/ariya/phantomjs/blob/master/examples/waitfor.js

或者可能这样：

driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS)

或者您要查找的ID位于框架/ iframe内，在这种情况下您需要使用

Driver.SwitchTo().Frame("frameIdentifier");

PhantomJS无法使用selenium webdriver找到该元素
