BDD that is the Behavior Driven Development is a very important programming language used in the development of software. This practice is implemented in Java with the help of using Cucumber - JVM which is also considered to be a mainstream tool. This framework of Cucumber is also used in Ruby on Rails other than Java.  

The business also well as non-technical users can write various scenarios and features with the help of Cucumber JVM. These are written in Gherkin texts.  

The step definition file is well supported by the feature file using which all the scenarios are properly executed. UI level tests alongside testing APIs can be done by combining with the Selenium WebDriver.  

12. What are the advantages of using Ruby on Rails?

Hooks are also known as executive Ruby blocks and are considered to be similar to the method of JUnit. They can also be placed under the support and has global application. Mainly three types of hooks exist - 

• Before: Mainly runs before the commencement of a scenario.  
• After: Runs after the commencement of a scenario.  
• Around: Runs around the scenario and also controls it.  

Certain other types of hooks are 

• Before Step  
• After step  

After configuration which runs after the configuration of the Cucumber test.  

14. Cucumber also works with the Browser Automation. How?  

The cucumber tool works with browsers like Selenium and WATIR-WebDriver. Build-in browser automation is not available in the Cucumber tool. It also works with another type of browser like the Active record by supporting their tests.  

15. Define Cucumber Command-Line Interface?
