Big Data Handling Techniques

Big Data Handling Techniques developed technologies. which includes been pacing towards improvement in neuro-scientific data controlling starting of energy. Hadoop has accomplished wide reorganization around the world. its success factors in the event of data handling. The reason many top multinational companies exhibiting involvement portions in this technology.

Issues of Data Handling

we realize the use of data has progressed over the period of a couple of years. there has been a lot of issues that are the producing outcomes of this enormous data usage. This issues to store massive levels of data, failures in effective processing of data. The incapability of effective handling of data along with other complex issues.

Hadoop technology is the best solution for solving the problems. that happen in the context of this enormous data stream. It helps the controlled stream of data along with the techniques for storing a large amount of data. that is being in use inside our day to day life.

Other Prominent Features Offered By Hadoop

It also helps the processing of enormous data over clusters of personal computers. Hadoop offers the ability to execute many concurrent responsibilities at the same time. Another feature Hadoop has bought is that it is very less susceptible towards errors.

Because of each one of these beneficial features, Hadoop put at the very top among the most advanced. It progressing technological fields surrounding the world. Hadoop coupled with Big Data Analytics performs role content of visualizing the data. which the market movements examined. this analysis predicts the near future market movements and makes strategies. that cause guaranteed success along with higher income.

Step Definition File

The next aim test or run the feature data file and test the feature record. The Step definition file required writing the execution or explanation of Definition Data file in C Clear. When SpecFlow executes a Part of a Scenario. it will choose a matching Step Explanation to execute 

SpecFlow Step Definition file

A Step Definition data file the small little bit of code with a pattern mounted on it or quite. Step Meaning a C# method in a category with an annotation above it. An annotation accompanied by the pattern employed to web page link matching Steps. the code SpecFlow will install when it perceives a Gherkin Keywords.

How to Build a Step Definition document?

It will always be good to have a nice and clean folder composition in the project. each folder signifies this content in it. So, first generate a folder for the Step Classification file.

Make a Step Definition Data file Folder

1) Create a fresh Folder by right click on the ‘Task’ and navigating to include -> New Folder.
2) Name the folder as ‘Steps’ and struck enter.

Build a Step Definition File

1) The color of the statements talked about in the feature file is violet. This means these statements don’t have any definition attached to it. It is very easy to put into practice all the steps. Right-click on feature file in the code editor. choose to Generate Step Definitions from the popup menu.
2) This display a POP-UP window. that may ask to choose the statements for Step Definition document created. Select all and select Generate button. Don’t forget to give it a rational name. In this case, I named it as ‘Login_Steps’, as all the steps in this will record related to end user Login.
3) It will ask to identify the folder path to save the Step Definition file. As a new Steps folder created to keep the definition file. Speak about the path for the same folder with the name of the Steps document. In this case, I have named it as ‘LogIn_Steps’. Struck Save button to move forward.
4) All the claims in the feature documentary will change the color now. it means these Feature statements associated with Step Definitions.
5) To have a go through the attached definitions, click on any assertion and press F12 button. This starts the linked explanation record and cursor directed to the associated definition.

Step Meaning method Implementation

This stuff is actually easy if you know how to work with Selenium. The last SpecFlow Feature Data file, straightforward case of LogIn features. Now start picking right up the code from the same Selenium Test Script and fit it into SpecFlow steps.

Add Selenium C# code to the Step Definition methods

1) Take the code for pursuing steps and fit it into the first approach to Step Definition Record:

‘Given User is at the Home Site’.

  • Kick off the Browser
  • Navigate to Home Page

2) Take the code for pursuing step and fit it into the second approach to Step Definition Data file:

‘And Navigate to LogIn Web page’.

  • Click on the Log in link

3) Take the code for the following step and fit it into the second method of Step Definition Data file:

‘When User gets into UserName and Security password’.

  • Enter Account

4) Take the code and fit it into the second method of Definition Data file:

‘And Go through the Log in button’.

  • Click on Submit button

5) Take the code for the following step and fit it into the second method of Step Definition Record:

‘Then Successful LogIN communication should screen’.

  • LogOut Button displayed
Run the SpecFlow Selenium Test 

The following steps are useful for How to run the Specflow Selenium test,

  1. To recognize all the test in the Feature File, go to check -> Windows -> Test Explorer.
  2. Notice, at the kept side a new window appeared called Test Explorer.
  3. Now to run an attribute Test. Right-click on the Test Explorer home window and choose Run Selected Assessments. This may run the determined test and screen the output in the gaming system window.



cucumber gherkin

cucumber gherkin examples

cucumber gherkin tutorial

Cucumber Gherkin not used to create automated exams. Gherkin used to write structured tests. which can later utilize as project documents. The property structured provides us the ability to automate them. This automation performed by Cucumber/SpecFlow

Types of Gherkin keywords

  • Feature
  • Background
  • Scenario
  • Given
  • When
  • Then
  • And
  • But
  • *

Feature: Keyword

Each Gherkin data file begins with an attribute keyword. Feature defines the rational test efficiency you will test in this feature record.

Record: Keyword

Background keyword used to explain steps. which are common to all or any the assessments in the feature record.
Background: Individual Logged In
Scenario: Search a product and add the first end result/product to an individual basket
Given User sought out Lenovo Laptop
When Add the first laptop that shows up in the search result to the basket
Then User container should screen with 1 item

Situation: Keyword

Each Feature will contain some quantity of tests to check the feature. Each test called a Scenario and is also defined using the Scenario: keyword.

Situation: Search a product and add the first consequence/product to the User basket
Circumstance: Successful LogIn with Valid Credentials

A scenario is the same as a test inside our regular development process. Each scenario/test broken down into three parts:

  • Precondition to the test, which stands for with (Given) keyword
  • Test step execution, which signifies with (When) keyword
  • Confirmation of the productivity with expected effect, which stands for with (Then)
Given Keyword

Given defines a precondition to the test. If the user is not at the house Page, the user would not be able to get into Username & Password. This precondition can be indicated in Gherkin like this:

Situation: Successful LogIn with Valid Credentials

  Given Customer is on WEBSITE
  When Individual Navigate to LogIn Page

When Keyword

When keyword defines the test action which will carry out. By test action, we say the user input action.
Situation: Successful LogIn with Valid Credentials
  Given Individual is on WEBSITE
  When End user Navigate to LogIn Site
  The customer is performing some action using When keyword, clicking on the Log in link. We can see that when defines the action used by the user. It is the event that may cause the actual change in talk about of the application.

Then Keyword

Then keyword defines the results of earlier steps. We are able to understand it best by looking at the test above and adding a Then step there.
Feature: LogIn Action Test
Information: This feature will test a login and LogOut functionality
Scenario: Successful Login with Valid Credentials
  Given Customer is on WEBSITE
  When Individual Navigate to LogIn Page
  And User gets into UserName and Password
  Then Message viewed LogIn

Here we can see that Then is the outcome of the steps above. The audience of the test would be able to relate with Then step and would recognize. the mentioned conditions satisfied then step executed.

And Keyword

And keyword used to add conditions to your steps.
that And is being used to add more details to the Given step, it’s adding more conditions. We added three conditions. Use it when you yourself have specified more than one condition. And used to include more conditions to Given, When and statements.

But Keyword

But keyword used to include negative type remarks. It isn’t a hard & fast rule to make use of but only for negative conditions. It seems sensible to use But when will try to add a disorder which is opposite to the idea your test is wanting to set.
Scenario: Unsuccessful Login with InValid Credentials
  Given User is on Home Page
  When Consumer Navigate to LogIn Page
  And User enters Account
  But The user qualifications are wrong
  Then Message displayed Wrong UserName & Password
view adding But has helped establish a negative test attempt to failure conditions. In which wrong credentials are a failure condition.

* Keyword

This keyword is very special. This keyword defines the complete purpose of having Given, When, Then and the rest of the keywords. In Cucumber doesn’t care about Keyword use to explain test steps. it cares about what code it requires to execute for each step. That code-named a step explanation and we’ll discuss any of it within the next section. Now, remember that the keywords changed by the * keyword as well as the test will work fine.
Here we conclude the guide on different keywords of Cucumber. I am hoping you prefer it. Let’s now jump deep into how to put in place these steps by making use of Step Definition record.



SpecFlow Feature File

History of SpecFlow Feature File


What is SpecFlow Feature File?

A feature file is an entryway to the SpecFlow test. That is a file where identify lab tests in Descriptive language. It an important part of SpecFlow, as it functions as an automation test script as well as live documents.

 History of SpecFlow Feature File

An attribute file can contain a scenario or many scenarios within a feature data file. it usually contains a set of cases. Let’s create one such file.
The head for writing the first script, let’s create a nice folder composition of the task.

Create a Feature File Folder

It will always be good to have a nice and clean folder framework in the job.Each folder signifies this content in it. So, first build a folder for the feature file.
1) Create a new Folder by right click on the ‘Task’ and navigating to include -> New Folder.
2) Name the folder as ‘Features’ and hit enter.
After the folder for feature document created, we have been all set to make a feature file.

Create a Feature File

1) Over the Feature folder Right-click and navigate to include -> New Item.
2) Select SpecFlow Feature File in the center. it logical name, with regard to this guide, please use the same name ‘LogIn_Feature’.
For SpecFlow to find the testimonies, It will need to make sure that they carry the ‘.feature’ file extension.
3) Write first feature file for LogIn Scenario.


A language named Gherkin. it implements the concepts of Business readable area specific language(BRDSL). Site-specific language provides the capability the application behavior without details of implementation.

If we have now come back to BDD/BRDSL we will see that we are able to describe checks in a more readable format. In the above test it’s quite clear and obvious, by reading, what test would do. At exactly the same time of being a test drive, it also documents the habit of application. The true power of BDD/BRDSL and it’ll become the electricity of cucumber works on the same principles.


Now moving forward we have described a test. You will notice colored part of the tests. They are keywords described by Gherkin.
Feature: Defines what feature you will be testing in the assessments
Given: Tells the pre-condition of the test
And: Defines extra conditions of the test
When: Defines the action of the test
Then: Says the postcondition. Able to say that it’s expected result of the test

Selenium Test using NUnit Framework

Selenium Test using NUnit Framework

What is NUnit Framework?

NUnit is a unit testing platform for performing unit testing based on the .NET platform. It is a trusted tool for unit testing and is preferred by many designers today selenium training in Hyderabad.

Selenium Test using NUnit Framework

NUnit absolved to use. NUnit does not create any test scripts alone. write test scripts on own, but NUnit gives to work with its tools and classes to make product trials easier. The details to keep in mind about NUnit are listed below:

  • NUnit is no automated GUI testing tool.
  • It is not a scripting dialect, all tests written in .NET backed languages, e.g., C#, VC, VB.NET, J#, etc.

What is NUnit Adapter?

The NUnit Test Adapter gives you to run NUnit testing inside Visual Studio.

Steps to Download and Install NUnit Construction using the NuGet Deals?

1) Go to Recommendations >> Manage Nuget Plans… from the answer Explorer window from the right side.
2) Type Nunit in the Search pack. This will need few seconds to find the right tool. Locate (seek out) NUnit in the center panel and showcase it by selecting it and Click Install.

Steps to Download and Install NUnit Adapter using the Extension Manager?

1) From within Visual Studio, go to Tools >> Extensions and Posts.
2) Seek out NUnit Test Adapter as soon as found select Install button.

How to choose between Expansion and NuGet package

The Extension will apply to Visual Studio room itself and can work with all projects you use. All users of your solution need to set up the Extension.
The Deal will apply to the solution and can work for any other end user too, as it follows the solution.

Steps to Create a NUnit Test

The very first thing need to do is to make a new course and write test code in that.
1) Right Click on the Project in the Solution Explorer and choose Add >> Class.
2) Give your Course name ‘NUnitTest’ and select Finish button. This will bring up a sugary class creation window.
3) Write the selenium code for the next steps

  • Take up a FireFox Browser
  • Start Website in the web browser started out by Selenium
  • Close the Browser

4) Separate the code into three different parts:

  • Take up a FireFox Browser: Initialize
  • Start Website in the internet browser began by Selenium: OpenTestApp
  • Close the Web browser: EndTest

5) Now Build the solution again by doing Build >> Build Solution.
6) Now use NUnit Annotations to specify your test. Use [SetUp], [Test] & [TearDown] for the three methods created above for every single action. And again run the Build
7) It’s enough time to run the NUnit test. To perform the test, Right Click in the Code window and choose Run Tests.

Steps to make a New Package

Now we are moving to learning Selenium. We are doing a lot of practice for Selenium Code. so it makes sense to create a different package for all the Selenium Test. To achieve that, we need to create a fresh folder into the project solution.
1) Right Click on the Project and select Add >> New Folder and name it Selenium Basics.

Selenium Test using NUnit Framework

We provide Selenium Test using NUnit Framework in real time training. We offer classroom and project training for selenium training in Hyderabad.
