Selenium is an open-source automation testing framework that can be used to test web applications across different browsers and operating systems. It is a popular tool for automating repetitive tasks and ensuring the quality of web applications.
Selenium works by interacting with the web browser through a driver. The driver is a software program allowing Selenium to control the browser and perform actions such as clicking buttons, entering text, and submitting forms.
What is Selenium Automation Testing?
Selenium automation testing is a software testing technique that uses automation tools to execute test cases against a web application. This helps to improve the efficiency and effectiveness of software testing and can help to identify bugs and defects earlier in the development process.
Selenium is an open-source automation testing framework that can automate web applications across multiple browsers and platforms. It is a popular choice for automation testing because it is easy to use, flexible, and extensible.
How does Selenium automation work?
Selenium automation testing works by interacting with a web application through a web driver. A web driver is a software program that allows Selenium to control a web browser. When a Selenium test script is executed, it sends commands to the web driver, which then interacts with the web browser to perform the desired actions.
For example, a Selenium test script might send a command to the web driver to open a web page, enter some text into a form, and click a button. The web driver would then execute these commands, and the web application would behave like a human user had performed the actions.
To automate a test using Selenium, you must first identify the web elements you want to interact with. Web elements can be identified using locators, which are strings that uniquely identify an element on the page. Once you have identified the web elements, you can write code to interact with them.
The basic steps involved in a Selenium automation test are as follows:
Create a WebDriver instance.
Navigate to a webpage.
Locate a web element on the webpage via locators in Selenium.
Perform one or more user actions on the element.
Preload the expected output/browser response to the action.
Run Test.
