Test Automation for Web applications

Test automation has specific advantages for improving the long-term efficiency of a software team’s testing processes. Test automation supports:-Frequent regression testing-Rapid feedback to developers-Virtually unlimited iterations of test case execution-Support for Agile and extreme development methodologies-Disciplined documentation of test cases-Customized defect reporting-Finding defects missed by manual testing

What is Selenium-Open source test tool for web applicationsSelenium project gathers a set of tools for writing automated tests of websites: Selenium RC (remote control), Selenium IDE, Selenium Grid and Selenium 2 (on beta) which is the next version of Selenium RC.These tools emerged from a javascript library that was used to drive interactions on a webpage on multiple browsers called Selenium Core.-Run in any mainstream browsers: IE, Mozzila/Firefox, Safari, Chrome-Write tests in many languages: Java, .NET, Perl, Phyton, Ruby Selenese(pure HTML, no Java/backend required)-Has ability to run whole suites of tests or individual test

What is Selenium used forSelenium primarily used for 3 purposes:-Functional Testing-User acceptance testing-Browser compatibility testing-Selenium is not meant for unit testing-It is used for Functional or System Testing-But not for Performance Testing

Selenium’s tool suite.1Selenium is composed of multiple software tools. Each has a specific role.1. Selenium IDESelenium IDE (Integrated Development Environment)is a prototyping tool for building test scripts. It is a Firefoxplugin and provides an easy-to-use interface fordeveloping automated tests. Selenium IDE has a recordingfeature, which records user actions as they are performedand then exports them as a reusable script in one of manyprogramming languages that can be later executed.

Selenium’s tool suite.23. Selenium 1 (aka. Selenium RC or Remote Control) is a server, written in Java, that accepts commands for the browser via HTTP. -RC makes it possible to write automated tests for a web application in any programming language-To make writing tests easier, Selenium project currently provides client drivers for PHP,Python, Ruby, .NET, Perl and Java. -It ‘injected’ javascript functions into the browser when the browser was loaded and then used its javascript to drive the AUT within the browser

Selenium’s tool suite.32. Selenium 2 (aka. Selenium Webdriver)-Selenium WebDriver is the successor to Selenium RC-Selenium WebDriver accepts commands (sent in Selenese, or via a Client API) and sends them to a browser. This is implemented through a browser-specific browser driver, which sends commands to a browser, and retrieves results.-Unlike in Selenium 1, where the Selenium RC server wasnecessary to run tests, Selenium WebDriver does not needa special server to execute tests. Instead, the WebDriverdirectly starts a browser instance and controls it. However, Selenium Grid can be used with WebDriver to execute tests on remote systems (see below).

Selenium’s tool suite.34. Selenium-Grid  -Selenium Grid is a server that allows tests to use web browser instances running on remote machines. -With Selenium Grid, one server acts as the hub. -Tests contact the hub to obtain access to browser instances. The hub has a list of servers that provide access to browser instances (WebDriver nodes), and lets tests use these instances. -Selenium Grid allows to run tests in parallel on multiple machines, and to manage different browser versions and browser configurations centrally (instead of in each individual test).

Advantages of Selenium- Open source, free software-Supports many browsers and many languages- Very mature and complete API-no dedicated machine required for test execution(user can work in parallel)- You can instantiate several concurrent tests with Selenium.
