Selenium C# errors
Element is not clickable at point (X, Y). Other element would receive the click…
Mistake Message
System.InvalidOperationException : unknown error: Element is not clickable at betoken (111, 700). Other element would receive the click: <div class="et_social_heading">…</div> (Session info: chrome=45.0.2454.93) (Driver info: chromedriver=two.fifteen.322448 (52179c1b310fec1797c81ea9a20326839860b7d3),platform=Windows NT half-dozen.1 SP1 x86_64)
The Problem
The problem here is that the chemical element that you are trying to click is either covered by some other element, or simply non visible. Hither is an case. If you go to ultimateqa.wpmudev.host and endeavor to click the Start Here button when you are a bit scrolled down, the header covers upward the button. As a result, even though the button is on the page, it is not clickable because the header is covering it upwardly.
The Solution
To fix this problem, y'all demand to brand the element visible. Specifically, Selenium tries to click on the exact center of the element. Your options are to scroll up, or hover over an element to close information technology, or minimize an expanded element. But put, make sure that your chemical element is visible for clicking. The heart of the element that yous want to interact with should not be obstructed by another element.
You lot tin scroll the element into view like this:
Or y'all can use the deportment class to movement to element earlier interacting with information technology like this:
There is already an selection for the browserVersion capability. Delight use the instead.
Error Message
Organisation.ArgumentException: 'There is already an option for the browserVersion adequacy. Please employ the instead.
Parameter proper name: capabilityName'
The Problem
With the introduction of the W3C spec, there volition be changes to the DriverOptions.cs from Selenium. This means that the old manner of setting the ChromeOptions or DesiredCapabilities will no longer be possible. So this will exist a new way to brand this happen.
The Solution
Set your DriverOptions through properties instead of passing in strings into theAddAdditionalCapability()
Here's a lawmaking sample for C# and setting ChromeOptions:
Btw, if you're struggling with Selenium and need my favorite resources, you might want to check these out.

The status of the exception was ReceiveFailure, and the message was: The underlying connection was closed: An unexpected fault occurred on a receive.'
InnerException
Unable to connect to the remote server
The Problem
Yous may have noticed that this page has one trend. Compatibility of Selenium WebDriver with a browser. This the largest burden in many of my backside, and has been for years now. This will probably go along until Selenium WebDriver is a W3C standard that is integrated into each browser. Until then, we will continue having these bug.
This fault occurred to me with:
- Chrome 56
- ChromeDriver 2.27
- Selenium WebDriver three.0.1.0
The Solution
- Update your Chrome browser to version 57.0
- This did the fob for me. Go on in mind that peradventure your versions of browser and ChromeDriver may exist unlike. Nonetheless, if you receive this fault, just upgrade your browser until it fits into the back up matrix of ChromeDriver release logs.

Today is your lucky day because I am going to assistance you resolve these really annoying errors!
The Trouble
The problem is a standard compatibility issue between Selenium WebDriver and your version of a browser. Equally I am writing about this, the latest WebDriver version is 2.53.1. The latest Chrome version is 51.0 and the latest Firefox version is 46.0. Therefore, the Selenium WebDriver API does not become updated every bit often as Chrome or Firefox.
When different types of browsers such as Chrome or Firefox get updated, there is a chance that this update volition break the Selenium API.
In our manufacture, this is known equally a regression. Therefore, when you get the latest version of your browser, y'all may be using a Selenium WebDriver version that does not support the latest features of that browser. At this point, you volition receive an ugly fault that looks like this:
System.TypeInitializationException
Now, y'all will spend the next day wondering how your Selenium code used to work yesterday and today it but stopped working.
The Solution
Downgrade your appropriate browser to the version supported past the latest Selenium Commuter. This might be Firefox, ChromeDriver, IEDriver then on.
In this example I teach you how to downgrade Firefox.
System.InvalidOperationException : unknown mistake: Chrome version must be…
Error Message

The Trouble
Another issue with compatibility of ChromeDriver with Chrome Browser. In this example it was Chrome version 48.0 not working with ChromeDriver version 2.27
The Solution
Upgrade your Chrome browser to the version supported by ChromeDriver. For example, ChromeDriver 2.27 supports Chrome 54 – 56 according to their release notes.
Could non copy "C… chromedriver.exe" to {some path}..

ExpectedConditions' is obsolete: ' implementation… deprecated
Error message
ExpectedConditions' is obsolete: 'The ExpectedConditions implementation in the .NET bindings is deprecated and will be removed in a time to come release. This portion of the code has been migrated to the DotNetSeleniumExtras repository on GitHub (https://github.com/DotNetSeleniumTools/DotNetSeleniumExtras)'
The problem
Wintertime is coming! And and so is Selenium 4.0 🙂 That's heady news because it means that it's getting improve. Nonetheless, this also means that at that place are some things that volition be deprecated. ExpectedConditions.cs will exist moving to a unlike Nuget bundle. Right at present, if you are using Selenium iii.X, this is just a warning. Later, y'all will not exist able to do this.
The Solution
I outlined the solution in depth hither
NoSuchElementException: no such element: Unable to locate chemical element
Error message
OpenQA.Selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"partial link text","selector":"Principal Automation With Selenium"}
(Session info: chrome=81.0.4044.138)
(Driver info: chromedriver=2.29.461591 (62ebf098771772160f391d75e589dc567915b233),platform=Windows NT x.0.18362 x86_64)
The problem
The element cannot be found on the page. This can happen when you are using an incorrect locator for your element, or when the chemical element has non been yet loaded on the folio.
The Solution
This problem has ii possible solutions:
Solution A
If the trouble is that the locator is incorrect, try using a different locator (by Id, Name, Xpath etc) and make sure that the locator corresponds to a single element on the page.
Solution B
If the problem is related to the loading time, add a wait, so Selenium will look a few seconds before throwing the exception if the element is non found.
- Implicit await (non really recommended)
WebDriverWait wait = new WebDriverWait(Driver, TimeSpan.FromSeconds(5));
Or
Driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(v);
- Explicit await
First, download the DotNetSeleniumExtras.WaitHelpers Nuget bundle.
Add this using statement to your class:
using ExpectedConditions = SeleniumExtras.WaitHelpers.ExpectedConditions;
Then add together the explicit await to your method:
WebDriverWait _wait = new WebDriverWait(Driver, TimeSpan.FromSeconds(5)); _wait.Until(ExpectedConditions.ElementIsVisible(locator));
You can find more than information on using the Explicit wait here.
