A Test Strategy - Selenium Web Driver

Automation technologies improve test coverage and yield higher quality products. They save thousands of manual test execution hours, significantly reducing costs. Selenium Automation Framework is a customized framework developed using Selenium, a widely accepted web application automation tool. It shrinks test cycle times and related costs.

Selenium is a portable software testing framework for web applications. The tests can be written as HTML tables or coded in a number of popular programming languages. They can be run directly in most modern web browsers. Selenium can be deployed on Windows, Linux and Macintosh.

SELENIUM WEBDRIVER- A TEST STRATEGY

Selenium is an automation tool for Testing, which are collection of different tools for Automation Testing. Learn more at selenium training in Bangalore. Selenium is not just a single tool but a suite of software, each catering to different testing needs of an organization. It has four components.

·         Selenium Integrated Development Environment (IDE)

·         Selenium Remote Control (RC)

·         Webdriver

·         Selenium Grid

Selenium Based Automation Regression Suite:

The below Selenium framework is a data driven solution consisting of:

·         Driver scripts developed in Java.

·         Test data provided in an Excel spreadsheet.

The Excel utility is developed in such a way that the URL based requests are dynamically created. While the driver code undertakes the following activities:

·         Reads the data from request column in an Excel spreadsheet.

·         Invokes the web browser and navigates to the URL based on the request.

·         Validates the response returned via browser body against the expected value in an Excel spreadsheet.

·         Updates the test case result in the spreadsheet.

Benefits of Selenium Framework:

·         Preparing the test data and validating each scenario manually takes approximately 10 minutes.

·         To prepare the data and validate 350 scenarios takes approximately 7 man days per resource. However, with the implementation of the recommended selenium framework the time is reduced to 1.5 hours (approximately).

·         Selenium framework is easy to develop and the test cases can be maintained effortlessly, as all the test scenarios and test data are driven off the Excel spreadsheets. Find information on selenium at selenium training institute in Bangalore.

·         This Selenium framework can be readily integrated with Continuous Integration (CI) build deployment process.

Why Webdriver:

WebDriver is a tool for automating testing web applications, and in particular to verify that they work as expected. It aims to provide a friendly API that’s easy to explore and understand, which will help make your tests easier to read and maintain. It’s not tied to any particular test framework, so it can be used equally well with JUnit, TestNG or from a plain old “main” method.

This “Getting Started” guide introduces you to WebDriver’s Java API and helps get you started becoming familiar with it. Webdriver allows your test scripts to communicate directly to the browser, thereby controlling it from the OS level.

·         To open source

·         To use a certain programming language in designing your test case

·         To test applications that are rich in AJAX-based functionalities

·         To execute tests on the HtmlUnit browser

·         Create scripts in Multi language (Java, perl, c# and phyton)

·         Run the Script on different type of browser.

Web Driver uses a different underlying framework from Selenium’s java-script Selenium-Core. It also provides an alternative API with functionality not supported in Selenium-RC. WebDriver does not depend on a JavaScript core embedded within the browser; therefore it is able to avoid some long-running Selenium limitations.The Selenium developers strive to continuously improve Selenium.

Advantages of Selenium Webdriver:

·         Improved features & functionality which were not supported in the Selenium 1.0

·         No need to start server prior to start executing scripts

·         Added advantage to support for iPhone and Android testing

·         It supports features like Page navigation, Drag-and-drop and AJAX-based UI elements

·         Using WebDriver can easily find the coordinates of any object

·         WebDriver is open source & it allows you to easily integrate with testing framework like JUnit or TestNG

·         It provides the improved reliability between browsers

·         For web application testing, it provides standard programming interface

Execution Process:

·         Here’s the process to execute the Selenium framework.

·         Provide the API URL values in the Excel spreadsheet.

·         Create a new spreadsheet for execution of reports.

·         Include the sheet number in the ‘exeSheetNum’ variable.

·         Add the execution report sheet number into the ‘reportSheetNum’ variable.

·         Click on the ‘Run’ button on the NetBeans IDE.

·         The NetBeans IDE automatically launches the ‘Internet Explorer’ browser and passes the URL value into the browser. Subsequently, it obtains the response value and compares it with the expected value, thereby displaying the results (PASS/FAIL).

·         After successful execution of all the above steps, the execution reports are updated in the spreadsheet number mentioned in the Selenium framework.

TestNG and JUnit:

TestNG and JUnit are the mostly used frameworks in selenium webdriver for reporting the bugs in document format like excel sheet. JUnit is a unit testing framework for the Java programming language. JUnit has been important in the development of test-driven development. To execute Selenium WebDriver testing using JUnit we have to add JUnit annotations in your test. Using these two methods we can have the inputs from excel sheet and process the inputs and generate the output by selenium result to excel sheet.

Functioning of Selenium Testing with Python

Selenium is a prominent open source apparatus that designers and specialized analyzers use for web program test computerization and cross-program testing. Tests can be composed with normal programming dialects, including C#, Groovy, Java, Perl, PHP, Python, Ruby and Scala.

Selenium is a test device that enables you to compose mechanized web application UI tests in any programming dialect against any HTTP site utilizing any standard JavaScript-empowered program. Selenium comes in two sections.

·             A server which can consequently dispatch and slaughter bolstered programs, and goes about as a HTTP intermediary for web demands from those programs. Variant 1.0 of the server was called Selenium Remote-Control (RC), adaptation 2.0 was called WebDriver.

·             Client applications that send orders to the Selenium server in an exceptional dialect (called Selenese) that reveal to it what operations to perform on the propelled web program.

The Selenium tool is one of the best devices accessible in the market for testing web applications. The interest for selenium training in Bangalore is instrument is additionally filled by its similarity to work with different programs and working frameworks when contrasted with different apparatuses in the market.

Selenium likewise offers adaptability as far as composing test scripts. It is a bit much that if the application is produced in one programming dialect, the scripts ought to be composed in a similar dialect. It is free of the dialect in which the site is made. For instance, if the application under test is produced in Python, it is not required that the scripts be composed just in Python, the test scripts can be composed in either JAVA or .Net.

Programming testing is a basic and vital piece of the product life cycle in the agile programming world. Testing is done end to end to distinguish issues and get them settled at each period of advancement. Testing confirms that the framework fits in with prerequisites including, useful, execution, unwavering quality, security and ease of use.

Advantages of Selenium:

·         Selenium offers numerous advantages when contrasted with other practical testing instruments.

·         Selenium is an open source and accordingly, there are no permit charges included. It is accessible for nothing download alongside its bolster benefit. Additionally, it has an expansive group of engineers.

·         It encourages executing relapse tests effectively and having snappy criticism about the application's status.

·         It permits running a similar arrangement of tests on various programs to distinguish utilitarian blunders recognized in one program and not in others.

·         It encourages running a similar arrangement of tests on various code branches (and programs) on the consistent schedule in a nonstop mix condition.

·         It permits running various tests in the meantime running the Selenium server on various ports.

·         Moreover, it incorporates well with famous devices, for example, Hudson, SauceLabs, Selenium-Grid, QMetry and others.

Web GUIs are commonly only a little piece of the usefulness that must be tried to decrease the dangers related with present day undertakings applications. Testing reasonable client exchanges may include end-to-tests that cover portable UIs, web administrations, ESBs, APIs, bundled applications, centralized servers, and even enormous information. Additionally, to guarantee that applications fulfill business desires—without deferring discharges—undertaking level testing likewise requires abilities, for example,

·         Advanced revealing and investigation

·         Sophisticated test information era and administration

·         Service virtualization

·         Risk scope streamlining

·         Integration with your "best of breed"

Selenium is a convenient programming testing structure for web applications. It gives a record/playback device for composing tests without taking in a test scripting dialect. It additionally gives a test-particular dialect called Selenese to compose tests in various prevalent programming dialects. The tests can be keep running against most web programs. Join best selenium training institute in Bangalore to learn more on selenium. Selenium is open-source programming and conveys on Windows, Linux and OSX stages.

Selenium with Python

Python is notable for its dynamic and basic nature. All dialects contend hard with Python in its diminished code form in few lines and quality for a typical situation. Selenium is solid to be utilized with the greater part of the prevalent dialects however adjusted with Python it produces awesome outcomes.

Why utilize Python over different dialects?

·         Easiness in coding and decipherability.

·         Runs quicker when contrasted and well known dialects, for example, Java.

·         Dynamic writing nature when contrasted and the static writing nature of Java.

·         Advantageous over conventional complex supports framework through straightforward spaces.

·         The Python APIs can be engaged to interface with the program through Selenium.

How does this function?

Selenium test works in a three level framework in particular,

·         Selenium mechanization code composed by Test design.

·         The program driven part which executes the code and sends its own particular demand to the program.

·         Browser for running program driven demands and restoring the reactions back.

The accompanying strides happen when the computerization script is executed.

·         HTTP ask for is made and sent to the program driver for every Selenium summon.

·         HTTP solicitations are served utilizing http servers by program driver.

·         HTTP server chooses suitable activities required for executing the Selenium summon.

·         The usage steps are done on the program.

·         The execution status is sent back to the HTTP server.

·         The HTTP server sends the status back to the robotization script.

Pattern of Selenium and Test Execution Using Selenium Grid

Ten years after its presentation, Selenium is ostensibly the most well-known open source testing apparatus, and in light of current circumstances. In this article will learn about which work extraordinary with selenium tests.

In addition to the fact that selenium is free and open, Selenium is likewise completely highlight and program unbiased. Change a solitary variable in the code, and a similar Selenium code that drives Internet Explorer can drive Chrome or Firefox. Change to a Mac and change the esteem, and it will run Safari.

Selenium WebDriver is broadly utilized as a first-decision structure with regards to testing web applications.

Page Object Pattern:-

Page Object is an idea that diminishes the quantity of copied code, and assists with test upkeep, coming about because of changes in the structure and usefulness of the web application. The primary thought behind page protest is to put the code identifying with the usefulness of subpages in particular classes- selenium training in Bangalore. In an exceptionally improved manner, if your web application incorporates pages:

·         home

·         about

·         contact

We ought to make three separate page question classes:

·         Home.java

·         About.java

·         Contact.java

Each class ought to contain just those techniques that bolster usefulness for the relating subpage, and characterize selectors just for this subpage. We ought to likewise recall, that open techniques in page question class are just those that speaks to client's work process.

One imperative point is that every open strategy in page protest class ought to return question of page that client is on. For instance, if a catch on the page does not get you to various subpages, this technique ought to restore this. Additionally, if a catch is a connection to another page, the technique ought to return page protest class of this subpage.

Page Factory design:-

The primary thought behind this example is to bolster page protest classes, and to permit better page selectors administration. Page Factory furnishes us with an arrangement of comments, which work incredible with selectors and improve code intelligibility.

What Do We Have?

Selenium is the true instrument for practical web tests. However, Selenium has its own constraints. Standard API permits associating just with the program, and it's difficult to test picture based applications utilizing Selenium.

By and large, Selenium's abilities meet prerequisites of practical web application testing. These standard tests will have the capacity to perform operations inside the program:

·         Locate components by the selector.

·         Retrieve their state.

·         Perform activities on UI.

Prerequisites:-

Giving an approach to Selenium Courses in Bangalore is testing a web application that uses a VNC customer is by all account not the only necessity. We have a bundle of additional necessities:

·         Use Selenium to compose some portion of the test which doesn't include a VNC customer test.

·         Be ready to execute tests in many strings on various machines to accelerate execution.

Plainly Selenium with its default highlights can't give us an approach to test visual substance on the page. However, the accessible arrangement of components given by Selenium is critical to our necessities.

It's Important to Understand How Tests Are Executed Using Selenium Grid:-

At the point when a test needs to keep running on a Selenium framework, it ought to pass design necessities for a hub. Selenium Hub knows all accessible hub setups. Utilizing this data, it chooses the fitting hub from the rundown and opens the session of selenium classes. After the session is opened, the test starts Selenium charges and sends them to the Hub. The center then passes summons to the hub appointed to that test. Hub runs the program and executes the charges inside that program against the application under test.

It is conceivable to expand Selenium Hub and Node with custom modules. This should be possible by making a custom servlet and enrolling it inside the arrangement record.

An excessive number of individuals attempt to create test techniques with UI mechanization and WebDriver however neglect to see long haul comes about. As a test specialist, it is a kind of judgment of our part, in light of the fact that when the venture has fizzled, the three to six-month test contractual worker is a distant memory.

As such, working with Selenium can be somewhat similar to the dim side of Force. Concentrating on reliable and stable test comes about, with a methodology around running the tests that incorporates full setup and teardown, can make your venture more like the light side than the dull.

What special features java programming is having from other programming languages

Java is one of the most popular language among the developers to develop the web applications, customized software and web portals, including E commerce and M commerce project.

Every programming language has some strength and weakness. As a developer, it is important to compare Java with other programming languages so that we will be able to select the proper language for a particular project.

1.   Difference between Java and Python :

(i) Java is not a pure object- oriented language where as Python is a fully object oriented high – level language.

(ii) Java is low – level implementation language on the other hand Python is a scripting language.

(iii) Python programs take time to run than Java programs ,that makes Java a favourable choice for enterprise level project .Java has rich library support for  some of the use cases than Python java course in bangalore

2. Difference between Java and C++ :

Java was derived from the C++ . But there are so many differences as the objectives for both languages are different.

(i) C++ is created mainly for system programming. It is extending the C language ,whereas Java is designed to support network computing.

(ii) When we  compare the libraries of Java and C++ languages, we will know that Java has a powerful cross-platform library. whereas ,C++ library is simple which is  providing containers

3.  Difference between Java and C# :

If we consider the security or performance then both languages are same.

(i) Java is a platform independent language. It is supported on multiple operating system than C# without recompiling code. C# is not platform – independent for example it runs on Mac OS-X and  Windows OS but it does not run on Linux platform.

(ii) C# is suitable for the 100 % job support Windows desktop or Windows phone application whereas Java is better for the Android phone application.

4. Difference between Java and Ruby :

Java and ruby both are the object oriented based languages and are strongly typed.

The difference is that in the method while executing the code Java code is first translated into machine code which runs faster than Ruby’s interpreted code.

About Java

- Java is an imperative language like C++, Ada, C, Pascal

- Java is interpreted like LISP, AP

- Java is garbage-collected like LISP, Eiffel, Modula-3

- Java can be compiled like LISP

- Java is object-oriented like C++, Ada, Eiffel

- Java is a successful hybrid for a specific-application domain, a reasonable     general-purpose language for non-real-time applications

 Conclusion

 It is a low level language to understand the basics by implementing the algorithms in the simplest form and at the same time high level enough to implement any task efficiently.
