Introduction to Selenium
Selenium is a free (open-source) automated testing suite for web applications that supports cross-browser and cross-operating-system interoperability. It is quite similar to HP’s QuickTest Pro (QTP, now UFT), only that Selenium focuses on automating web-based applications. Testing done using the Selenium tool is usually referred to as Selenium Testing.

Selenium is useful for testing web applications only. Neither desktop (software) testing nor the testing of mobile applications is possible with Selenium.

A web application is an application program stored on a remote server that is allowed to get accessed through a web browser over the Internet. Many websites contain web applications. Any website component that performs functions for users qualifies as a web application.

Selenium is an automation testing tool; it is primarily used to test websites and web applications; it is an open-source tool. With the help of Selenium, test cases can run directly in web browsers, just like a person operating the web browsers. It supports many web browsers such as Opera, Safari, Chrome, Firefox, IE, etc. There are several different sub tools to support different automation test approaches. In this article, we will learn about selenium tool suite, its components and features. So let’s start!!!

You’d hardly find a website these days without alerts and pop-ups! The alert boxes warn you whenever you perform a wrong action or to enter details to access a website. These alert boxes stop you from performing any other browser functions till the alert is resolved. This is why it becomes important that you handle them in your Selenium test automation scripts.
In this WebDriverIO tutorial on alert handling in Selenium, I’ll show you how to handle alerts and pop-ups as well as overlay modal in WebDriverIO. I will also cover the different types of alerts you will face during automation and what are the key points you need to follow for alert handling in Selenium using WebDriverIO.
It is important to note that you can’t identify alerts using devtools or by XPath. Also, since they can’t be handled as a window, this is why it gets a bit tricky to handle them, but don’t worry, you’d find more about this in the latter section of this WebDriverIo tutorial.
There are three types of alerts that you’d need to handle in WebDriverIO.
The alert pop up or alert() method displays an alert box with just a message and ‘OK’ button. This alert used to inform the user about some information. There is only one button ‘OK’ displayed with the text of information. Here, the user has only one option to press the OK button. Below is the example of alert pop up.
The confirmation alert is the second type of alert with a message, where it gives the user the option to press OK or Cancel. Here is the example of a confirmation alert.
The prompt pop up is the last alert where this used to let the user give input for the website. Here, the user can give input and press the OK button or press Cancel to avoid giving input. Below is the example of the prompt pop up.
< div > tag by giving special CSS code. This modal can go off by clicking somewhere other than the modal.
This modal is built using the client-side framework e.g bootstrap, ReactJS. A developer can be used to display some information, pop up, and form. There is no special
Here is an example of Overlay Modal:

The first and foremost topic that you would learn in this WebdriverIO tutorial is going to be the WebdriverIO architecture. This is what happens when you run a WebDriverIO test script.
WebdriverIO: WebdriverIO built on top of NodeJS which communicates with NodeJS.
This flow gets executed when the user runs WebdriverIO test script:
Selenium Grid has been an integral part of automation testing, as it lets you perform test case execution on different combinations of browsers, operating systems (or platforms), and machines. It also enables you to perform parallel execution to expedite the cross-browser testing process.
Selenium Grid 4, the successor to Selenium Grid 3, has been in the Alpha stage for the last couple of months. The developer community was very excited regarding Selenium 4 (Alpha), and the addition of several useful features such as Selenium 4 Relative Locator has helped accelerate activities related to Selenium test automation. Selenium 4 Alpha features an improved Selenium Grid design; the significant change is the introduction of ‘fully distributed mode.’ In this Selenium 4 tutorial, we take a deep dive into Selenium 4 and the vital architectural differences in comparison to Selenium 3.
