The Problem

The problem here is that the chemical element that you are trying to click is either covered by another chemical element, or simply not visible. Here is an example. If you lot become to ultimateqa.wpmudev.host and try to click the Start Hither button when yous are a flake scrolled downward, the header covers upwards the button. Every bit a result, even though the button is on the page, it is not clickable because the header is roofing it up.

Chemical element non clickable example

The Solution

To fix this trouble, you need to make the chemical element visible. Specifically,  Selenium tries to click on the verbal middle of the element. Your options are to curl up, or hover over an chemical element to close it, or minimize an expanded element. Simply put, make sure that your element is visible for clicking. The center of the chemical element that you lot want to interact with should non exist obstructed by some other chemical element.

You can roll the element into view like this:

Or y'all tin employ the actions class to move to element before interacting with it like this:

An exception with a null response was thrown sending an HTTP request to the remote…

Fault Message

Similar to the fault above, merely it's slightly dissimilar in wording and message.

The status of the exception was ReceiveFailure, and the bulletin was: The underlying connection was closed: An unexpected mistake occurred on a receive.'

InnerException

Unable to connect to the remote server

The Problem

You may have noticed that this folio has one tendency. Compatibility of Selenium WebDriver with a browser. This the largest burden in many of my behind, and has been for years at present. This will probably keep until Selenium WebDriver is a W3C standard that is integrated into each browser. Until and then, we will go on having these issues.

This error occurred to me with:

• Chrome 56
• ChromeDriver ii.27
• Selenium WebDriver 3.0.1.0

The Solution

• Update your Chrome browser to version 57.0

System.TypeInitializationException

System.TypeInitializationException: System.TypeInitializationException: The type initializer for 'Framework.Browser' threw an exception. —> OpenQA.Selenium.WebDriverException: Failed to showtime up socket within 45000 ms. Attempted to connect to the following addresses: 127.0.0.1:7055.

Or something like this?

OpenQA.Selenium.WebDriverException : Unexpected mistake. System.Net.WebException: Unable to connect to the remote server —> System.Cyberspace.Sockets.SocketException: No connectedness could be made because the target auto actively refused information technology

Today is your lucky solar day considering I am going to help you lot resolve these really annoying errors!

The Problem

The trouble is a standard compatibility result betwixt Selenium WebDriver and your version of a browser. Every bit I am writing near 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 as oft as Chrome or Firefox.

When unlike types of browsers such as Chrome or Firefox get updated, in that location is a chance that this update volition break the Selenium API.

In our industry, this is known as a regression. Therefore, when you get the latest version of your browser, you may be using a Selenium WebDriver version that does non support the latest features of that browser. At this point, you will receive an ugly fault that looks like this:

System.TypeInitializationException

Now, you will spend the next 24-hour interval wondering how your Selenium code used to work yesterday and today it just stopped working.

The Solution

Downgrade your appropriate browser to the version supported by the latest Selenium Driver. This might be Firefox, ChromeDriver, IEDriver and so on.

In this case I teach y'all how to downgrade Firefox.

This portion of the lawmaking has been migrated to the DotNetSeleniumExtras repository on GitHub (https://github.com/DotNetSeleniumTools/DotNetSeleniumExtras)'

The problem

Winter is coming! So is Selenium four.0 🙂 That's exciting news because information technology ways that it'south getting meliorate. However, this also means that there are some things that volition be deprecated. ExpectedConditions.cs will be moving to a different Nuget package. Right now, if yous are using Selenium 3.X, this is just a warning. Later, you will not be able to practice this.

NoSuchElementException: no such element: Unable to locate element

Error message

OpenQA.Selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"partial link text","selector":"Master Automation With Selenium"}
(Session info: chrome=81.0.4044.138)
(Driver info: chromedriver=2.29.461591 (62ebf098771772160f391d75e589dc567915b233),platform=Windows NT 10.0.18362 x86_64)

The problem

The chemical element cannot be plant on the page. This can happen when you are using an wrong locator for your chemical element, or when the chemical element has not been yet loaded on the folio.

The Solution

This problem has two possible solutions:

Solution A

If the problem is that the locator is wrong, try using a dissimilar 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, and so Selenium volition look a few seconds earlier throwing the exception if the element is not found.

• Implicit wait (not really recommended)

WebDriverWait look = new WebDriverWait(Commuter, TimeSpan.FromSeconds(5));

Or

Commuter.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(5);

• Explicit wait

Commencement, download the DotNetSeleniumExtras.WaitHelpers Nuget package.
Add this using statement to your grade:

using ExpectedConditions = SeleniumExtras.WaitHelpers.ExpectedConditions;

Then add together the explicit wait to your method:

WebDriverWait _wait =  new WebDriverWait(Driver, TimeSpan.FromSeconds(v)); _wait.Until(ExpectedConditions.ElementIsVisible(locator));

You can find more information on using the Explicit wait here.
