10 Reasons Why You Should Learn Selenium

On the off chance that you’re perusing this blog, the odds are that you either need to kick-begin your profession in the IT field or you need to develop from being a manual tester to turning into an automation tester. In any case, you are at the correct place since YOU have to learn Selenium.

You may likewise need to know, how to begin a profession in testing, and if Selenium is the correct track to begin. In the event that such inquiries hold on, don’t stress on the grounds that, in this blog, I will give you 10 persuading reasons why you ought to learn Selenium.

Top 10 motivations to learn Selenium are:

1. Open source
2. No OS/ browser demands
3. Multi-Language Support
4. Availability of Frameworks
5. Strong presence in the DevOps lifecycle
6. Easy integration
7. Parallel & distributed testing
8. No dependency on GUI based systems
9. Flexibility while designing test cases
10. Demand for Selenium testers

I’ll explain these points in my next post.

Don’t Automate Every Test

100% Test Coverage is beyond the realm of imagination since there can be a huge number of mixes. We generally execute a subset of possible tests. A similar rule applies to automated testing.

To make an automated script, it requires time and exertion, and going for “automating Each Test”, we require a lot of resource and time, which in many cases is beyond the realm of imagination.

Rather, utilize a Risk-based way to deal with figure out which tests should be automated. To get the most incentive out of automation, just automate the most important business cases and scenarios.

Likewise, a high number of automated tests adds maintenance cost and hard to maintain.

Another note to keep remember is that not all tests can be automated. A few tests are extremely unpredictable in nature and require numerous downstream system checking and can be conflicting. In these cases, it is best to leave these checks for manual testing.

Software Testing Need

Software testing is the place everything comes down to. The present universe of innovation is totally commanded by machines, and their behavior is controlled by the software driving it. Will the machines act precisely as we need them to? Every-time? All over the place? The response to these inquiries lies in software testing.

Toward the day’s end, it is the software application’s prosperity rate which will control your business development. A similar thing can be said for web applications in light of the fact that most organizations today are totally dependent on the web.

Take, for instance, any internet business organization. Be it Amazon or E-Bay or Flipkart, they depend on the client movement on their sites and activity on their mobile applications for business.

Envision, if something calamitous happens like the costs of various items being topped off at 10$, all as a result of a little bug in a “not all that effectively comprehensible” some portion of the code. At that point what should be possible, and how might we avoid it in the future?

By testing the code before deployment right? So, that is the requirement for software testing.

Here I’ll like to introduce you with Selenium testing tool. It is the best automation testing tool available in open source testing tools. You may ask, what is Selenium? To get the answer you can visit this blog. It has many articles about selenium.

Before I go any further, let me clear out that, Software testing is of two sorts: Manual Testing and Automation Testing. Selenium was established as an automation testing tool to overcome the disadvantages/restrictions of Manual testing. Along these lines, in the following area of this what is selenium blog, how about we comprehend the difficulties with manual testing.

Introduction to Selenium

There are many testing tools in market like QTP, SilkUI, and Selenium and so on. However, individuals lean toward Selenium because Selenium is an open source (i.e. you can download this tool free of cost) automation testing tool. We have QTP likewise for automation testing yet you have to pay to HP folks on the off chance that you need to utilize QTP.

You can work on multiple operating systems using Selenium. Selenium is the only tool which can work on MAC, Windows, Linux, and Solaris.

It is used only for web-based applications. QTP can work on windows but Selenium can be used only for web-based applications or websites.

By using Selenium, you can work on multiple OS. Selenium is developed to work at MAC, Windows, Linux, and Solaris.

Platforms supported By Selenium:

• Windows
• OS X (Mac OS)
• Linux
• Solarsis

Presently, it supports mobiles too. There is another tool called Appeium which is an expansion to Selenium. Appeium offers help to IOS and also Android.

Languages used with Selenium:

You can write Selenium code in any language mentioned below:

• Java
• C#
• Ruby
• Python
• PHP
• Perl

NOTE: In the event that your application is based on one language, you may use any other language to automate it. Like if your application is created in C# and to automate its testing you may use Java.

SO THE LANGUAGE WHAT YOU WRITE YOUR AUTOMATION CODE IS INDEPENDENT OF THE LANGUAGE WHAT YOUR APPLICATION IS BUILT ON.

Browsers supported by Selenium:

• Internet Explorer
• Firefox
• Chrome
• Safari and many more

Selenium is the only tool which supports cross browsers testing.

Due to such a large number of features (like various language support, numerous browser, different OS support) given by Selenium, it is so well known in the market.

Selenium History:

Selenium came into existence in 2004 when Jason Huggins was testing an internal application at ThoughtWorks.

 Available versions of Selenium:

• Selenium 1.0 – formally we call it RC (Remote control server).

It is officially depreciated by Selenium team.

The purpose behind Depreciation is:

Selenium 1.0 Architecture:

• Selenium 2.0 –Web Driver
• Recently Selenium 3.0 version also came (for it minimum java version required is 1.8)

Selenium 2.0 Architecture– Web Driver:

So we are conquering the first disadvantage of Selenium 1.0.

How the second disadvantage is survived:

Editor instead of using java to trigger the events, utilizes Browsers own/native language to trigger the events (or to converse with the application). Suppose our Firefox browser is built in Java so to converse with a site which is running on Firefox, editor use java. Our IE is based upon C# so editor uses C# to converse with the application in C#. The site which is running on IE can’t stop C# to trigger an event so hence the second issue is settled.

Working of Selenium WebDriver:

Selenium WebDriver working can be clarified in 2 different ways:

• Nontechnical- using the analogy
• Technical

Nontechnical- using the analogy:  To explain working, the analogy used is taxi driving.

The manner in which a cab driver drives a taxi, same way Selenium WebDriver drives a browser.

In taxi driving, there are 3 sections:

• The customer, who chooses where to go and how to arrive, he advises this to the cabbie.
• The cab driver, the cab driver, who goes about according to the customer’s solicitations and sends his very own solicitations to the vehicle.
• The vehicle, it goes about according to cabbie’s solicitations.

So also, in Selenium WebDriver test automation (and other tools), there are 3 sections:

• Test engineer, who writes the automation code, which sends requests to the browser driver component.
• The browser driver component, who executes the test requests, sent by the engineer, it sends its own request to the browser.
• The browser, who executes the browser driver requests.

So this is the analogy:

1. Test engineer <-> The customer
2. The browser <->Cab driver
3. The browser <->Vehicle(Car)

Technical explanation :

Beneath steps happen when the automation script is executed:

• For each Selenium command, an HTTP request is created and sent to the browser driver
• Using the HTTP server, the browser driver get the HTTP requests
• The HTTP server implements the Selenium command and executes them on the browser
• The execution status is sent back to the HTTP server which in turn sends the status back to the automation script.

Selenium Job Roles

The mainstream programming testing work titles after doing Selenium WebDriver training are:

• Quality Engineer
• Automation Test Lead
• QA Engineer
• Selenium Automation Analyst
• Senior Test Engineer

Who should choose Software testing as a career?

• One who is good in comprehending intelligent riddles: Software will go to the market if a tester says there are no bugs in the product and it is prepared to release. Tester discovers bugs and likewise breaks the framework as far as stress testing.
• One who love helping other people: A tester help in releasing a quality product to the market. To release a decent product, engineers give a valiant effort. Yet at the same time risks are there will be a few errors. Being a tester you have to discover those mix-ups.
• One who loves to take challenges: A tester needs to investigate the framework for comprehension and discovering bugs. At that point, he reports the bugs, which are settled by the engineer. Thus, at last, a quality product is conveyed to the market.
• One who loves coding: An Automation Tester writes code to discover the bugs in the framework. And in this way, a quality product will be conveyed.
• One who loves to communicate with people: A tester needs to associate with engineers and client to get more information on domain knowledge.
• One who loves to be in a team where quality products will be delivered: Being a tester one help in conveying a quality product which makes everyone cheerful.

Selenium Summary – IDE, RC, WebDriver, Grid

In my previous posts, I have shared details about all selenium segments. Below is the summery.

The whole Selenium Tool contains four segments:

1. Selenium IDE, a Firefox add-on that you can just use in making generally basic test cases.
2. Selenium RC also called Selenium 1. It is the first Selenium tool which allows users to use the programming language to make complex test cases.
3. WebDriver, the more up to date. It allows your test scripts to communicate directly to the browser.
4. Selenium Grid is used with Selenium RC to execute parallel tests across different browsers and operating systems.

Selenium RC and WebDriver were merged to frame Selenium 2.
