Selenium

Selenium

Selenium is one of the most popular open source Web UI (User Interface) automation testing tool. Jason Huggins was originally developed in 2004. Selenium supports automation across different browsers, platforms and programming languages. On operating systems like Windows, Linux, Solaris, and Macintosh, Selenium can be simply installed.

Selenium is an open-source suite of tools for automating web browsers, which can be used for testing web applications, scraping websites, or automating repetitive tasks in a browser. It is primarily used for automating tests for web applications and supports multiple programming languages, including Python, Java, C#, and Ruby.

Selenium consists of several components:

1. Selenium WebDriver: an API that allows users to write scripts that interact with a browser as a user would.

2. Selenium Grid: a tool that enables parallel execution of tests across multiple machines, allowing for large scale, distributed testing.

3. Selenium IDE: a browser plugin that provides an easy-to-use interface for creating and running Selenium tests.

Selenium can be used with various browser types, including Chrome, Firefox, Safari, and Internet Explorer, and can be run on various operating systems, including Windows, macOS, and Linux. Additionally, Selenium integrates with various testing frameworks, such as JUnit, TestNG, and Mocha.

Automation Testing:- 

Automation testing is a method of testing software applications where tests are executed automatically, without manual intervention. The aim of automation testing is to increase efficiency, speed up the testing process, and improve overall software quality by detecting and fixing defects early in the development process.

There are various tools and frameworks available for automating tests, including Selenium, Appium, TestComplete, and many others. You can create test scripts using these tools in a number of different programming languages, including Java, Python, C#, and others.

The tests can range from simple unit tests that test individual code components to complex end-to-end tests that cover multiple components and interactions. Automated tests can also be integrated with continuous integration and continuous delivery (CI/CD) pipelines to ensure that tests are executed every time new code is committed or deployed.

However, it's important to note that automation testing is not a replacement for manual testing, as manual testing still plays a critical role in the testing process. Automation testing should be seen as a complement to manual testing, helping to increase the speed, efficiency, and reliability of the testing process.

Automation Testing Life Cycle

Automation Testing Life Cycle is a process that outlines the steps involved in automating the testing of software applications. It typically involves the following stages:

Test Planning: This stage involves defining the scope of testing, identifying the objectives and goals of the test, and determining the testing strategy. This includes identifying the testing tools and framework to be used, selecting the automation testing team, and creating a test plan.

Test Design: In this stage, the automation testers create test cases and test scripts based on the requirements and specifications of the software application. The test cases are designed to cover all possible scenarios, including both positive and negative test cases.

Test Development: This stage involves the actual development of the automation scripts. The automation testers use a chosen scripting language and automation tool to create automated test scripts that can execute the test cases.

Test Execution: In this stage, the automated tests are run against the software application. The automation testers execute the automated test scripts and generate reports that provide information on the pass/fail status of each test case.

Test Reporting: After test execution, the automation testers generate reports that provide a detailed summary of the test results. The reports should provide an overview of the testing process, including the test objectives, testing strategy, test cases, test execution, and results.

Test Maintenance: The automation testers must maintain the automated test scripts and ensure they remain up-to-date with any changes made to the software application. This includes updating test scripts, fixing defects, and incorporating new test cases as necessary.

By following the Automation Testing Life Cycle, organizations can ensure that the automation testing process is well-defined, consistent, and efficient, thereby reducing the time and effort required for software testing while improving the quality of the software application.
