Initially Cucumber was implemented in Ruby and then extended to Java framework. Both the tools support native JUnit. Cucumber can be used along with Selenium, Watir, and Capybara etc. It supports many languages like java, Perl, PHP, Python, .Net etc.

One can use it more in different project environments., as it is very easy to learn and implement. One should apply BDD framework to API automation.The inbuilt runner for cucumber is JUnit but we can also use testng with it. BDD is most promising framework in industry because it shows interactions between a BA and automation engineer.  Cucumber is more like using COBOL. Write the tests in a more conventional programming language, like Ruby, Java, PHP, Python, C#, Haskell, Go, whatever. And Cucumber is not a testing tool. It is a tool to help non-technical people understand tests. If programmers are going to test a RESTful API, then they will achieve more by using a familiar programming language to write those tests.

Django is a web framework written in Python. Django follows explicit is better than implicit (a core Python principle), resulting in code that is very readable even for people that are not familiar with the framework. A project in Django is organized around apps. Each app has its own models, controllers, views and tests and feels like a small project. Django projects are basically a collection of apps, with each app being responsible for a particular subsystem.

Why Ruby on Rails is good for Web Development ::

• Both frameworks were born out of the need of developing web applications faster and organizing the code better. They follow the MVC principle, which means the modelling of the domain (model), the presentation of the application data (view) and the user’s interaction (controller) are all separated from each other. Django actually considers the framework to be the controller, so Django addresses itself as a model-template-view framework. Django’s template can be understood as the view and the view as the controller of the typical MVC scheme. Ruby on the other hand mainly lies in the area of web development and offers really great libraries in that field, from the web application itself over deployment libraries to things like foreman which helps you to start a big set of microservices simultaneously on your local device.
• —  Sites that would traditionally take 12 weeks to build can commonly be launched inside of 6 weeks with Ruby on Rails. This time savings results from a few factors: a leaner code-base (fewer lines of redundant code), a modular design (re-using existing components rather than building everything from scratch), and the availability of existing plugins (again, reducing the need to build features from scratch).
• —   After site launch, future modifications to your site (e.g., adding new features, making changes to the data model) can be made more quickly, for the same reasons noted above.
• —    Because of the speed with which Rails sites can be built and modified, one will spend less money to create and maintain the website — without compromising the quality, performance, or scalability of your site.

One common distinction between a scripting language and a language used for writing entire applications is that, while a programming language is typically compiled first before being allowed to run, scripting languages are interpreted from source code or bytecode one command at a time. Scripting languages are not compiled to machine code by user like other programming languages. They are high level code which are interpreted by another program dynamically or at runtime. Scripts are set of instructions either to the web browser (client side)which are embedded in HTML, or to the server side that interface to databases or other data stores on the server. A scripting language can be viewed as a domain-specific language for a particular environment; in the case of scripting an application, this is also known as an extension language. Scripting languages are also sometimes referred to as very high-level programming languages, as they operate at a high level of abstraction, or as control languages, particularly for job control languages on mainframes. Scripting languages are programming languages that don’t require an explicit compilation step.
