I am new to automated testing. I am using C#, Selenium and Chrome 99 with the correct driver. I am trying to get to an anchor tag on the page.

Here is my code that is not working,

driver.Url = "abc.com"; //cant display the real one
driver.FindElement(By.XPath("//a[@href='ubEntryQueue.aspx']")).Click();

The error I am getting:

OpenQA.Selenium.NoSuchElementException
  HResult=0x80131500
  Message=no such element: Unable to locate element: {"method":"xpath","selector":"/a[@href='ubEntryQueue.aspx']"}
  (Session info: chrome=99.0.4844.74)
  Source=WebDriver
  StackTrace:
   at OpenQA.Selenium.WebDriver.UnpackAndThrowOnError(Response errorResponse)
   at OpenQA.Selenium.WebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters)
   at OpenQA.Selenium.WebDriver.FindElement(String mechanism, String value)
   at OpenQA.Selenium.By.<.ctor>b__11_0(ISearchContext context)

   at OpenQA.Selenium.WebDriver.FindElement(By by)
   at CLQTesting.WQ.ValidateWQDisplays() in C:\QA\CLQTesting\WQ.cs:line 30

This was my last attempt

Here is what I am trying to get to enter image description here

  • What happens if you add a breakpoint to the driver.FindElement call and run in debug mode? Specifically, is the link visible on the browser screen? It looks like there are parent elements of the link that are set not to display - this will hide all child elements so Selenium would be unable to find them.

  • that makes sense. How can I get around this? Displayed=false when I debug it. I thought that might be the issue but not sure how to get around it.

The problem is that the parent div (and possibly other parent elements as well) has a style attribute of display:none which prevents any child elements from displaying.

There are several ways to get around this problem.

  1. Program the actions needed to make the target element display. This may or may not be feasible depending on the way the site works - the HTML snippet shown in the question suggests that a lot of JavaScript is used to handle changing visibility and expanding elements.
  2. Use the WebDriver JavaScriptExecutor class ExecuteScript method to edit the style directly. To do this, you will need to get a reference to a parent of the element with display:none, then use ExecuteScript to traverse the DOM and delete the display:none style tag. From there you can proceed as normal.
  3. Use JavaScriptExecutor to click the link directly. This is probably the simplest method.

You can find a decent guide to using JavaScriptExecutor here. (I found the link with a quick Google search. No affiliation)
