What is Selenium?
Selenium is a popular open source framework used for automated testing of web applications. It supports working with various browsers, including Chrome, Firefox, Safari and Edge, and allows you to automate user actions such as clicks, form filling, navigation and more.
The main components of Selenium:
- Selenium WebDriver is a library for managing browsers.
- Selenium IDE is a tool for recording and reproducing tests.
- Selenium Grid — allows you to run tests in parallel on multiple machines and browsers.
How does Selenium work?
Connecting to the browser:
Selenium WebDriver manages browsers through their API.
Writing tests:
Test scripts are created using programming languages such as Python, Java, C#, Ruby or JavaScript.
Running tests:
Tests automatically reproduce user actions in the browser and check the expected results.
Analysis:
The test results help to identify errors in the operation of a web application or website.
Python code example:
from selenium import webdriver
driver = webdriver.Chrome()
driver.get("https://example.com")
print(driver.title)
driver.quit()
Why do people choose Selenium?
- Support for multiple programming languages:
Flexibility allows you to integrate Selenium into existing development. - Multiplatform:
