  • open-source tool
  • Its focus on end-user experience
  • Cucumber tests are written in plain-text English so individuals with no or less technical skills may also write scenarios
  • It allows us to involve business stakeholders who can’t easily read a code
  • Allows quick and easy setup and execution
  • High reusability of code in the tests
  • It can be integrated with Selenium and other testing frameworks like JUnit & TestNG
3.Define BDD?
BDD is a procedure of developing software based on TDD (test-driven development) which focuses on the behavioural terms of software testing units.
4.Define programming language that is used by Cucumber?
Cucumber tool provides the hold for various programming languages such as Ruby, .NET, Java etc. It may also be included with several tools such as Capybara, Selenium etc.
5.What is the aim of a Scenario Outline in Cucumber?
Scenario outline could be the approach of parameterization of scenarios. This is iobviously utilized when the same scenario needs to be executed for multiple sets of data, however, the test steps remain the same.

  • When
  • Then
  • And

Two files required to execute a Cucumber test scenario are
  • Features
  • Step Definition
9.Name any two testing framework that can be integrated with Cucumber?
  • JUnit
  • TestNG
10.What is meant by a feature file?
A feature file should provide a high-level description of an Application Under Test (AUT). The first line of the feature file should begin with the keyword ‘Feature’ followed by the description of the application under test.A feature file may include multiple scenarios within the same file. It has the extension .feature.
11.What is Step Definition in Cucumber?
A step definition is the actual code implementation of the feature mentioned in feature file.While feature files are written in an easily understandable language like, Gherkin, Step Definition files are written in programming languages such as Java, .Net, Ruby, etc.
12.Define test harness?
A test harness for cucumber and rspec enables for separating accountability between setting up the background and interacting with the browser and cleaning up the step definition files.
13.Define regular expressions?
A regular expression is a pattern recounting a definite amount of text. The essential regular expression consists of a single literal character.
14.Name the Framework Design which can be implemented in Cucumber?
  • Page Object Model
  • Log4j
  • Extent Reporting
  • Dependency Injection (Example: Pico Container)
  • Object Repository
15.What is the meaning of the TestRunner class in Cucumber?
TestRunner class is used to provide the link between the feature file and the step definition file. The next question provides a sample representation of how the TestRunner class will look like. A TestRunner class is generally an empty class with no class definition.
16.What is the use of glue property under the Cucumber Options tag?
Glue property is used to let the Cucumber framework identify the location of step definition files.
17.What is the language used for expressing scenario in feature file?
Gherkin language is used to express scenario in feature files and ruby files containing unobtrusive automation testing for the steps in scenarios.
19.How to generate reports with Cucumber?
We can generate the output/report of the cucumber using different cucumber commands.
>cucumber adding.feature –format HTML
>cucumber adding.feature –out report.html
>cucumber adding.feature –format pretty
The report file will be stored in the project folder itself.
20.What are Tags in cucumber-bdd?
Cucumber tags are used to organize scenarios in your feature file. Example: @regression, @sanity, @EndtoEnd
Tags are used to
  • Group scenarios
  • Ignore scenarios from execution
