5 Selenium Web drivers Mistakes You Might Not Know About


We’ve all made mistakes when writing code, but when it comes to writing testing code, slipping in a few mistakes can make your whole project explode! Learn about some of the most common Selenium Web Driver mistakes and how to avoid them.


What is Selenium?


Selenium is a web driver that you can use to automate your tests. Selenium can be used to test websites, applications, and even desktop applications. Selenium can also be used to create interactive user interfaces. Selenium has many features that make it a powerful tool for testing.

One of the most common mistakes people make when using Selenium is forgetting to context switch. Context switching is the process of taking control of the browser from the Selenium driver and controlling it like you would a regular web browser. This allows you to perform typical web browsing tasks like clicking links and filling out forms. Context Switching is important because it allows you to simulate real-world interactions with your software under test.

Another common mistake people make with Selenium is trying to use too many features at once. It’s important to break your tests down into smaller, more manageable goals so that you can track progress and ensure successful completion. When working with Selenium, it’s also helpful to have a development environment set up in advance so that you can reference your actual code while testing.


How to Install Selenium IDE


If you’re new to Selenium, it can be helpful to install the Selenium IDE. The IDE provides a user interface for managing and running tests from a single location. You can also use the IDE to create and manage test scripts, as well as contribute to open source projects.

To install the Selenium IDE, follow these steps:


1) Download and install the latest version of the Selenium IDE.


2) Open the application launcher on your computer and search for “Selenium” or “Web Driver”.


3) Click on the Selenium icon to launch the IDE.


4) Click on the Preferences button in the toolbar and select the Installation tab.


5) Select either “Install locally” or “Download and install”.


6) Click on the Install button next to “Selenium Web driver”.


7) Confirm that you want to install Selenium by clicking on the Yes button.


8) Once installation is complete, restart your computer if prompted.


9) The Selenium Web driver installation folder will be placed in your default browser installation folder (for example, C:\Program Files\Google\Chrome).


Types of Selenium Web Driver Errors


There are various types of Selenium Web Driver errors that you might encounter while using the software. These errors can occur when trying to interact with a web page, when using the Selenium IDE, or when using Selenium RC. In this blog post, we will discuss some of the most common Selenium Web Driver errors and how to fix them.


The “Web Driver not installed” error


This is one of the most common Selenium Web Driver errors. When you try to install or launch the Selenium Web Driver, you might get this error if it is not already installed on your computer. To solve this problem, you need to install the Selenium Web Driver on your computer first.


The “No Such Element Exception” error


When you try to load a web page into the Selenium Web Driver, you might get an “No Such Element Exception” error if there is no element in the target website that matches the name of the element that you are trying to load into your driver instance. This problem can be solved by specifying a matching attribute for each element that you want to load into your driver instance.


The “Invalid State Exception” error


When you try to use certain commands in the Selenium IDE, you might get an “Invalid State Exception” error if your browser is in a different state than what was specified in


5 Common Selenium Web Driver Mistakes


If you’re new to Selenium, or are just starting out with Web Driver, there are a few things you should know about common mistakes. Here are five of the most commonly made mistakes:


1. Not setting the Firefox driver as the default


By default, Selenium uses the Firefox driver. If you’re not sure which driver to use, we recommend setting Firefox as your default driver. This way, all of your tests will run using that specific driver. 


2. Not verifying your test scripts


When writing tests, it’s important to verify that they work as expected. This means running them through a debugger and checking for any errors. By doing this, you can avoid unexpected failures in your tests and ensure that your code is accurate.


3. Failing to set up expectations correctly


Before running any tests, it’s important to set expectations for what will happen during the test cycle. This way, you can avoid any surprises when testing occurs.


4. Running untested code in a Selenium environment


Before running any untested code in a Selenium environment, make sure to test it on a separate machine first! This way you can be sure that the code will work as expected before deploying it into a production environment.


5. Ignoring browser compatibility issues


Browser compatibility issues can cause unexpected errors when testing code in a Selenium environment. Make sure to check for these issues before running tests and fix them if necessary!




Selenium is a powerful tool that can be used in web development to automate tasks and improve the quality of your code. However, like any other tool, it can also cause problems if not used correctly. In this article, I have listed five Selenium mistakes that you might not know about. Hopefully, by reading this you will avoid making these common errors and instead use Selenium to its full potential.
