Within this Blog, you will learn about the Selenium applications testing tools and steps.
Advantages of Implementing Selenium Software Testing Tools
- Repeated Evaluation Cases Execution
- A large test matrix analyzing
- Caters Parallel Execution
- Hastens Unattended Execution
- Reduces human generated errors consequently improves accuracy
- Time and money saving.
It Resulted in
- Higher Return on Investment (ROI)
- Faster GoTo Industry
There are numerous advantages of automation analyzing, known well and mainly discussed during the program test industry.
Why To Chose Selenium For Automating Web-Based Applications Testing?
- Open source
- A big user base and assisting communities
- Multi-platform and browser compatibility
- Active repository developments
- Multiple language implementations encourage
Selenium supports a broad selection of browsers, technologies, and platforms.
Components of Selenium
Selenium is called a'Suite Package' using several testing applications. Each tool is designed to offer several testings and evaluation environment conditions.
Selenium Suite Offers Following Sets Of Tools
- Selenium Integrated Development Environment (IDE) -- As a plugin to firefox documents, plays and export tests in different languages.
Based on it HTML’,'HTML test situation' is the most appealing format.
- Selenium Remote Control (RC) Additionally referred selenium 1' -- It will help to perform the exported evaluation in various OS/platform.
- Selenium Grid -- A variety of selenium machines could be controlled with it.
Also, it's typically not only necessary for loading test, so you can ignore it.
- Selenium WebDriver -- It is the latest version of this Selenium.
Supports several languages, the Android Testing & iPhone testing also.
In a mixture Selenium RC and also WebDriver, are Called Selenium 2.
According to Above, Selenium RC alone can also be referred as Selenium 1.
More About Selenium Tools
SeleniumCore
An engineer named Jason Huggins in Thought Works is having the charge to develop Selenium with his constant efforts.
While he was focusing on the testing of an inner Time and Expenses application, he recognized the need to eliminate repetitive manual tasks for an automation testing tool without compromising with the precision and quality.
In early 2004, a JavaScript app named "JavaScriptTestRunner" is developed, much similar to that of a user communicating with the browser which could automatically control the browser's tasks.
So, this instrument was presented before a large audience and finally categorized in the Open source class using its potential to grow as a re-usable testing framework for additional internet programs, later on, this tool acclaimed as"Selenium Core".
Selenium IDE
Even the Selenium-IDE (Integrated Development Environment) is a simple to use Plugin for firefox plus among the most popular automated testing instrument amongst the testing pros to record and playback tests i.e.
QTP, WinRunner to develop test cases for Selenium.
The recorded test can be then exported into various languages e.g. HTML, Java, .net, pearl, Ruby etc.. Moreover, using"selenium remote management", exported evaluation can be run in any browser and platform.
Additionally, Selenium-IDE contains a context menu which helps to pick a UI component from the currently displayed page of the browser.
Selenium RC (Selenium Remote Control)
Selenium RC arise as an effect to overcome a variety of problems incurred by Selenium IDE or Core. It is written in Java that helps an individual to develop test scripts for a web-based program in a programming language of user's decision.
When utilizing Selenium Core, various restrictions and loopholes made the testing process a cumbersome and also a far-reaching job for the user to leverage the entire benefits of the program.
As an example, While launching the JavaScript Program out of "https://www.seleniumhq.org/”, the pages will be accessed inside precisely the same domain such as "https://www.seleniumhq.org/projects/” or "https://www.seleniumhq.org/download/”.
However, the other domain names such as google.com, yahoo.com wouldn't longer be available.
Thus, to defeat the problem of the same source policy, the user has to install the whole program over the Selenium Core as well as a web server.
Thus, Selenium RC came to existence, in order to govern the exact first coverage without the necessity of earning another copy of the application under test to the Selenium Core.
Selenium RC supports a Wide Variety of browsers and platforms, Unlike selenium IDE
Description for Workflow
- In a desirable programming language, user generates test scripts.
- There is a designated client library, for each programming language.
- The evaluation commands are deported to the selenium machine by the Client library.
- The evaluation commands are changed and deciphered into JavaScript commands by Selenium server and it sends them into the browser.
- Employing selenium core, the browser executes the commands and results are delivered directly back to the selenium server.
- Finally, the test results delivered to the customer library from the selenium server.
Before producing Selenium RC scripts, a Couple pre-requisites are there to be set up
- An Integrated Development Environment -- either Eclipse or Netbeans etc.
- A Programming Language -- Java, C#, Python etc..
- A Framework for Testing (optional) -- JUnit, TestNG etc.
- And of course a Selenium RC installation.
Selenium Grid
The emerging tendencies on multiple browsers and platforms concurrently demand to do different or same test scripts.
So as to deal with the demand for executing the test suites simultaneously on multiple stages, Pat Lightbody introduced Selenium Grid. Thus, a tester's lifestyle is now positive and favorable using all the Selenium Grid to reach dispersed test execution, examining under different environments and unusually saving implementation time.
SeleniumWebDriver
In the calendar year 2006, a second engineer named as Simon Stewart created Selenium WebDriver in ThoughtWorks. Having a subtle difference using Selenium RC, WebDriver is also an online testing tool.
No significant functioning of JavaScript was demanded since it was built on the fundamental in which an isolated client was created for every one of their internet browsers. A stronger automated testing tool was developed called as Selenium two, using a compatibility analysis involving Selenium RC and also WebDriver.
WebDriver is only object-oriented and blank frame. Without using any peripheral thing, it uses the browser's native compatibility to automation.
It has gained a huge user base and recognition with the rising demand.
Selenium 2
WebDriver is clean and also a purely object-oriented frame. It utilizes the browser's native compatibility with automation without having any peripheral entity.
Webdriver merging with Selenium(2.0) allows Selenium tests to run even without a browser (and suitable for load test). Selenium 2 does not face the javascript limitations due to the usage of the native plug into the browser to conduct its tests.
With the rising demand, it's gained large popularity and user base.
Selenium 3
An advanced version of Selenium 2 is referred as Selenium 3. It's a mobile and web applications focused instrument for automation.
Together with the extension of WebDriver API, Selenium 3 affirms the cellular testing needs. Much anticipated that this tool will be launched soon on the marketplace.
