Selenium Automation Tool- Remarkable Features

Selenium is an open source web application computerization mechanical assembly by ThoughtWorks (IT outsourcing association). It has 4 portions. Out of which one section i.e. Selenium Remote Control was made by a Jason Huggins gather in 2004.

It was fundamentally made in DHTML/Javascript when they were wearing down time and cost application written in Python programming vernacular. A short time later, Simon Stewart has developed another part that is called as Webdriver in 2006 to beat the disadvantages looked in Remote Control. Moreover, post that Remote Control and Webdriver were joined and made Selenium Webdriver.

They have named this instrument as Selenium in light of a blend segment in Chemistry which is used to destroy Mercury compound segment. Mercury gadget which is by and by called as UFT was the most noticeable computerization instrument.


It has 4 particular portions that are:

  • Selenium IDE (Integrated Development Environment)
  • 1.0 (Also called as Remote Control)
  • 2.0/3.0 (Also called as Webdriver)
  • Selenium GRID

It reinforces different working structures, various projects and diverse lingos. It gives you flexibility to pick the vernacular in which you have capacity. Following is the summary:

  • Multiple Programming Languages : Java, Python, PHP, Ruby, Perl, JavaScript
  • Multiple Operating Systems : Android, iOS, Windows, Linux, Mac, Solaris
  • Multiple Browsers : Chrome, Internet Explorer, Edge, Opera, Safari et cetera

It is known for its execution and execution speed. We should discuss the particular sections of it:

  1. Selenium IDE:

It is a record and play mechanical assembly and a module of firefox. This module is used to make models of tests. Following are the features of this mechanical assembly:

  • Easy to present
  • Test Scripts are made by essentially tap on record get
  • Can record, adjust and investigate substance
  • Simplest way to deal with learn Selenium phonetic structure.
  • Test Scripts can be outside made in different lingos like Python with Remote Control, Java with Webdriver, Java with Remote Control, Ruby with Remote Control et cetera
  1. Selenium 1.0 (Remote Control):

This was the principle section made in Selenium Suite. It wound up well known by virtue of this part. It works in following way:

  1. Using this portion, we form test substance which partners with Remote Control Server.
  2. Server deciphers the code and changes over it into javascript and moreover injected into the projects.
  3. Javascript gets executed at the program and response is sent back to the server which progresses it to the customer.

There were various hindrances in this gadget that is:

  • Confusing orders.
  • Remote Control Server goes about as a go between which makes its execution slower.
  • Use of Javascript
  1. Selenium Webdriver (2.0/3.0):

After Selenium RC, Webdriver has come which make its outline all the more less intricate. By and by, there is no server. Test Scripts team up particularly with the program. The execution is extensively speedier stood out from Remote Control. Commands were segregated in different classes which end up being straightforward for end customer to recall and to complete.

Multi year back, It has impelled another frame that is 3.0 which is impressively lighter thanĀ  2.0. There are next to no change done which influence the end customer yet extraordinary were done at the backend. Sentence structure for stacking Firefox has been changed to following:

System.setProperty(“webdriver.gecko.driver”,”path to gecko driver”);

Webdriver driver = new FirefoxDriver;

  1. Selenium GRID:

It is used for parallel testing. This section engages us to execute robotization framework on different machines put at different zones. Nevertheless, every one of the machines should be related on a Local Area Network. It can be used with Remote Control and what’s more with Webdriver. In the event that it’s not all that much inconvenience observe that Remote Control classes have been rebuked now. Thusly, we couldn’t use this portion with Remote Control.

Things which Selenium offers anyway others doesn’t are:-

  • No Fee i.e. Free Tool (A more noteworthy factor)
  • Support for various tongues you can use Java, C#, Python and ROR et cetera to make test cases.
  • Lots of Testing frameworks to peruse (others have only a solitary pre-described structure to be used).
  • Execute tests in parallel on various OS, program blends using Selenium Grid
  • Supports all the common projects and structures (others too support different projects)
  • Integrate with DEV and CI condition perfectly
  • Most basic: Already created and all the additionally creating usage of Selenium in electronic testing, that generally every QA opening notification that individual should consider Selenium. Thusly, an awesome motivating force to your calling, scope of capacities and resume.

Test Automation Tool – Selenium for Web Applications

Many, possibly most, programming applications today are formed as online applications to be continued running in an Internet program. The sufficiency of testing these applications varies extensively among associations and affiliations. In a time of exceedingly natural and responsive programming shapes where various affiliations are using some sort of Agile framework, test computerization is from time to time transforming into a need for programming wanders. Test Automation is routinely the fitting reaction. Test robotization suggests using an item gadget to run repeatable tests against the application to be attempted. For backslide testing this gives responsiveness.

There are various inclinations to test motorization. Most are related to the repeatability of the tests and the speed at which the tests can be executed. There are different business and open source gadgets available for assisting with the change of test automation. Selenium is possibly the most by and large used open source game plan. This present customer’s guide will help both new and experienced Selenium customers in learning practical techniques in building test computerization for web applications.

This present customer’s guide presents Selenium, demonstrates its features, and shows frequently used acknowledged systems assembled from the Selenium social order. Various cases are given. Moreover, specific information on the internal structure of Selenium and endorsed jobs of Selenium are given.

Test automation has specific inclinations for upgrading the whole deal capability of an item gathering’s attempting methods. Test automation supports:

  • Frequent backslide testing
  • Rapid feedback to architects
  • Virtually limitless cycles of test execution
  • Support for Agile and ludicrous progression theories
  • Disciplined documentation of trials
  • Customized deformation declaring
  • Finding relinquishes missed by manual testing

To Automate or Not to Automate?

Is automation continually advantageous? Right when might it be a smart thought for one to automate test cases?

It isn’t for the most part great to robotize test cases. There are times when manual testing may be more appropriate. For instance, if the application’s UI will change amazingly within the near future, by then any automation ought to be revised regardless. In like manner, now and again there basically isn’t adequate time to produce test motorization. For the transitory, manual testing may be more fruitful. In case an application has a tight due date, there is correct currently no test robotization available, and it’s essential that the testing complete inside that time traverse, by then manual testing is the best course of action.

Test Automation Tool – Selenium

Selenium is a game plan of different programming gadgets each with a substitute method to manage supporting test motorization. Most Selenium QA Engineers revolve around the perhaps a couple mechanical assemblies that most address the issues of their assignment, in any case adjusting each one of the instruments will give you an extensive variety of decisions for advancing toward different test automation issues. The entire suite of gadgets achieves a rich course of action of testing limits especially adjusted to the necessities of testing of web employments of different kinds. These errands are incredibly versatile, allowing various decisions for discovering UI segments and taking a gander at expected test comes to fruition against honest to goodness application lead. One of Selenium’s key features is the assistance for executing one’s tests on various program stages.

Brief History of the Selenium Project

Selenium at first jumped up in 2004 when Jason Huggins was attempting an internal application at ThoughtWorks. Being a sharp individual, he comprehended there were favored livelihoods of his chance over physically wandering through comparable tests with each change he made. He developed a Javascript library that could drive correspondences with the page, empowering him to subsequently rerun tests against various projects. That library over the long haul advanced toward getting to be Selenium Core, which underlies all the convenience of Selenium Remote Control (RC) and Selenium IDE. Selenium RC was notable because no other thing empowered you to control a program from a tongue of your choice.

While Selenium was a gigantic mechanical assembly, it wasn’t without its drawbacks. In perspective of its Javascript based automation engine and the security obstacles programs apply to Javascript, differing things wound up hard to do. To compound the circumstance, webapps ended up being progressively fit after some time, using an extensive variety of extraordinary features new projects give and making these constraints additionally anguishing.

In 2006,

an overcome originator at Google named Simon Stewart started tackle an assignment he called WebDriver. Google had for quite a while been a generous customer of Selenium, yet analyzers expected to work around the obstructions of the thing. Simon required a testing mechanical assembly that spoke direct to the program using the ‘neighborhood’ system for the program and working structure, along these lines keeping up a key separation from the confinements of a sandboxed Javascript condition. The WebDriver wander began with the arrangement to settle the Selenium’ torment centers.
