Before I get started, let me tell you what you will get to learn by the end of this blog Need for software testing. Challenges with manual testing. How automation testing beats manual testingSelenium vs. Selenium suite of tools Selenium is an automation testing tool. Wait, before you get carried away, let me inform you that only testing of web applications is possible with Selenium. We can neither test any desktop software application nor test any mobile application using Selenium. It a bummer, I can feel your pain. But dont worry, there are many tools for testing software and mobile applications like IBMs RFT, HPs QPT, Appium and many more. But, the focus of this blog is, testing dynamic web applications and why Selenium is the best for that purpose. Before going into further details of Selenium, you ought to know the story behind how Selenium came into being what it is today. Need For Software Testing. Software testing is where it all boils down to. Todays world of technology is completely dominated by machines, and their behavior is controlled by the software powering it. Will the machines behave exactly as we want them to Everytime EverywhereThe answer to these questions lie in software testing. At the end of the day, it is the software applications success rate which is going to control your business growth. The same thing can be said even for web applications because most businesses today are completely reliant on the internet. Take for example, any e commerce company. Be it Amazon or E Bay or Flipkart, they rely on the customer traffic on their web sites and traffic on their web based mobile applications for business. Imagine, if something catastrophic happens like the prices of a number of products being capped off at 1. Then what can be done, and how can we prevent it the next timeBy testing the code before deployment right So, this takes us to the next topic of manual testing. Introduction To Probability Models Solution Manual 9Th Grade here. Challenges With Manual Testing. What is Selenium Selenium automates browsers. Thats it What you do with that power is entirely up to you. Primarily, it is for automating web applications for. Manual testing refers to the fact that, the web application being tested is done manually by QA testers. Tests need to be performed manually in every environment, using a different data set and the success failure rate of every transaction should be recorded. Look at the above image of a poor chap, who manually verifies the transactions recorded. The challenges he is facing cause fatigue, boredom, delay in work, mistakes and errors because of manual work. This leads to the need for automation testing. Automation Testing Beats Manual Testing. Automation testing beats manual testing every time. Why Because it is faster, needs less investment in human resource, not prone to errors, frequent execution is possible, supports lights out execution, supports regression testing and also functional testing. Lets take a similar example to the one mentioned earlier. Suppose there is a login page and we need to verify if all the login attempts are successful, then it will be really easy to write a simple code which will validate if all the transaction login attempts are a success or not automated test case execution. Moreover, these tests can be configured in such a way that they are tested in different environments and web browsers. What else can be done You can automate the generation of result file, by scheduling it for a particular time during the day. Then you can also automate the generation of reports based on those results and what not. The key point is that automation testing makes a testers job a whole lot simpler. Check out the image below which shows a more relaxed environment in which the same tester is working. Now, let me talk about Selenium in particular. What Is Selenium Selenium is a suite of software tools used to automate web browser testing. It is an open source tool and is mainly used for functional testing and regression testing. Since it is open source, there is no licensing cost involved, which is a major advantage over other testing tools. Other reasons behind Seleniums ever growing popularity are Allows testers to write Selenese code in 7 different programming languages  Java, Python, C, PHP, Ruby, Perl and Java. Script. It is not limited to, any environment and it allows testers to perform tests on various operating systems  Windows, Mac, Linux, i. OS and Android. Testing can be done on different web browsers  Mozilla Firefox, Internet explorer, Google Chrome, Safari and Opera browsers. Most of all, we can integrate it with frameworks like Test. NG, JUnit NUnit for managing test cases and generating reports. But there surely has to be shortcomings right We can use Selenium only to test web applications. We cannot test desktop applications or any other software. There is no guaranteed support available for Selenium. We need to leverage the available customer communities. It is not possible to perform testing on images. We need to integrate Selenium with Sikuli for image based testing. There is no native reporting facility. But we can overcome that issue by integrating it with frameworks like Test. NG or JUnit or NUnit. Learn Selenium From Experts. Now let us see where Selenium stands in the market. Selenium vs. QTP vs. RFTI have compared its performance with two other popular tools QTP and RFT in the table below. Features. HP QTPIBM RFTSelenium. License. Required. Required. Open source. Cost.

It is pretty clear from the above table why Selenium is the most preferred tool. In the next part of what is Selenium blog, lets go into the depths of Selenium by understanding the different flavors it comes in. Selenium Suite Of Tools. Selenium RC Now depreciatedSelenium IDESelenium Grid. Selenium Web. Driver. Selenium RC Remote ControlBefore I talk about the details of Selenium RC, I would like to go a step back and talk about the first tool in the Selenium project. Selenium Core was the first tool. But, Selenium Core hit a roadblock in terms of cross domain testing because of the same origin policy. Same origin policy prohibits Java. Script code from accessing web elements which are hosted on a different domain compared to from where the Java. Script was launched. To overcome the same origin policy issue, testers needed to install local copies of both Selenium Core a Java. Script program and the web server containing the web application being tested so they would belong to the same domain. The permanent solution to this problem turned out to be Selenium RC. What does RC do then RC overcame the problem by involving an HTTP proxy server to trick the browser into believing that Selenium Core and the web application being tested come from the same domain. Thus making RC a two component tool.
