Introduction to Selenium

Selenium is an open-source, portable, software testing framework that is used for automating web-based applications. It is one of the most widely used testing frameworks for web-based applications.

Syntax

Selenium provides a variety of methods and functions that can be used for automating web-based applications. Below are some examples of Selenium syntax:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome()
driver.get("http://www.google.com")
assert "Google" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("Selenium")
elem.send_keys(Keys.RETURN)

Example

Let's consider an example scenario of testing a login page using Selenium. In this scenario, we would like to test the following scenarios:

  • Verify that the login page loads successfully
  • Verify that the user is able to login successfully
  • Verify that the user is unable to login with incorrect credentials

Using Selenium, we can automate these scenarios by writing scripts that interact with the login page and its elements.

Output

Selenium provides various output options to view the results of the automation test:

  • Console output – The console can be used to view the output generated by the test script
  • JUnit – Selenium can be configured to output test results in the JUnit XML format
  • HTML – Selenium can generate a test report in HTML format for viewing the test results

Explanation

Selenium can automate browser actions such as clicking links, filling forms, and navigating through pages. It supports various programming languages such as Java, C#, Python, Ruby, and JavaScript. Selenium also supports multiple browsers such as Chrome, Firefox, Safari, and Edge.

Use

Selenium is primarily used for automating web-based applications. It can be used by software testers, developers, and quality assurance professionals for automating various test scenarios. It can also be used for regression testing, performance testing, and integration testing.
