Rail is a framework of ruby language that is used to create complete web applications and Restful API for mobile applications. It is an open-source web framework that follows the MVC design pattern, MVC means Model, View, and Controller. Model is used to create data access layer, the view is used to created user access layer and controller is used to create business access layer and application intermediate layer. MVC flow is different from their name because the first controller layer will start the application after that model and the view layer will be loaded. MVC is the modern design pattern, that follows by many application technologies. SPRING MVC in JAVA, ASP.NET MVC for .NET, Laravel and Codeigniter for PHP, DJANGO for Python, and Rail for Ruby. Rails Architecture:- How to install ruby:- gem install rails

................................................................................................................................................................... it is another way of software testing which provides automated software tools to execute test cases based on the test script. The test script will be written in the programming language according to automation software tools. Manual testing is better for the waterfall model but it will take more time to implement testing operations in the agile model because the agile model will use regression testing (continuous testing of the application from end to end ) which is not possible by manual testing. Name of automation tools:- 1 QTP (Quality Test pro):-                                     VB Script 2 Selenium Web Driver:-                              ...

It is an Automation Framework that provides a set of annotations to create and execute a test script. It provides a structured approach to writing code that is easily understandable by automation developers. it provides a test script, test code, and annotation to write a program. It is upgraded from Web Driver and a modified form of JMeter. TestNG Command, Locators are similar to Web Drivers. TESNG Provides HTML Test REPORT With all Test methods separately. Type of Annotation:- @Test // it represents Test Method @Test void fun1() { } ........................................................................................................................... @BeforeTest:- This annotation will be executed before the Test Method, It will be declared only once in one Test Class. @AfterTest:- This annotation will be executed after the execution of all Test methods .it will be declared only once in one test case. @Test:- It is used to create a Test Case Method, We can create more than ...

It is a Web-based Framework of Python which provides MVT(Model, View, Template) Design pattern to create a Dynamic web application. Django MVC is also known as MVT architecture. MVT means Model, View, and Template,   Model is used to provide a data access layer, View is used to provide business access layer or Code layer,  and Template is used to provide user access layer or design. Why Django is best as compare to other frameworks:- 1) Django contains predefined libraries to create secure, reliable, and Fast dynamic web applications. 2) Django Framework is Open Source so that we can easily customize the Django Framework program code and structure. 3) Django provides rapid application development tools because it has an inbuilt app to create a login , admin dashboard, user management (ACL access control list ),  Session management, etc. 4) Django Framework can easily be integrated with HTML, CSS, JS, and Jquery to design web pages. 5) Django Framework ...

This class will be compiled by Java Compiler and executed by JVM under  Servlet container by Web Server. A Servlet container is used to manage the servlet code that is written on the java programming language of an application, Webserver is only used to manage static files (HTML, JS, CSS, Jquery) and JSP Web page but dynamic content will be managed by Servle...

ReactJS is a declarative, efficient, and flexible JavaScript library for building reusable UI components.  It is an open-source, component-based front-end library responsible only for the view layer of the application.  It was created by Jordan Walke , who was a software engineer at Facebook.  It was initially developed and maintained by Facebook and was later used in its products like WhatsApp & Instagram.  Facebook developed ReactJS in 2011 in its newsfeed section, but it was released to the public in the month of May 2013. Today, most of websites are built using MVC (model view controller) architecture.  In MVC architecture, React is the 'V' which stands for view, whereas the architecture is provided by the Redux or Flux . A ReactJS application is made up of multiple components, each component responsible for outputting a small, reusable piece of HTML code.   The components are the heart of all React applications . These components can be nested wit...

Project --------> Project URL-----> App URL ------> View           Method 1) When we run the Django project then the first projec t urls.py will be loaded 2) Project urls.py file contains a collection of app URLs means if we create 5 different apps then five different app URLs will be declared here 3) app urls.py file contain the path of the method which will be defined under view What is the difference between project and app:-  A project is a collection of the app for example if we create a project for a feedback system then the student app, faculty app, admin app will be different components of the project. app contain views.py ,templates for html file,css file,image,js,jquery,model e tc means app is the complete component of project.
