Top BDD Interview Questions and Answers

BDD Framework Interview Questions and Answers

1. What is BDD?

Ans: Behavior-driven development (BDD) is developing software based on Test Driven Development (TDD) that focuses on the behavioral specification of software testing units. 

2. What is Cucumber?

Ans: Cucumber is an automation testing framework based on Behavior Development (BDD) methodology, which tests software applications without any programming skills. It increases the quality of testing and reduces the difficulty.

The Cucumber is an open-source tool that supports the English language specifications required for testing. Other technical methods to use the programming languages are .NET, Java, and other platforms. The cucumber specifications include various scenarios and examples.

3.What is the profile in Cucumber?

Ans: Profile in cucumber allows a way to define a group of tests in a feature file to run a selected group instead of executing all the commands while testing a feature. Cucumber profiles allow running step definitions and features.

Use the command below to run the cucumber profile. 

Cucumber features -p<profile_name>

4.What are the main files required to run a Cucumber test scenario?

Ans: The Two main files used to run a Cucumber test scenario are 

  • Step Definition

  • Features

5.Explain the term step definition in Cucumber?

Ans: A step definition is the actual code implementation of the feature mentioned in the feature file.

6.What is the language used by Cucumber?

Ans: Gherkin is the language that is used by the Cucumber tool. It is a simple English representation of the application behavior. Gherkin language uses various keywords to define application behavior such as Feature, Given, Scenario, Scenario Outline, Then, When, etc.

7. What is meant by a feature file?

Ans: A feature file offers a high-level description of an Application Under Test (AUT). It consists of the following components:

  • Feature: It defines the implementation of the current test script.

  • Scenario: It is the expected outcome and steps for a specific test case.

  • Scenario outline: It can be executed for multiple sets of data.

  • Given: It defines the context of the text to be implemented.

  • When: It specifies the test action that has to perform.

  • Then: The expected outcome of a test can be represented by “Then.”

8. Why use Cucumber with Selenium?

Ans: Cucumber and Selenium are two well-known technologies. Many companies are using Selenium for functional testing. These organizations using Selenium want to integrate Selenium with Cucumber as it helps to read and understand the application flow.

9. What software do you need to run a Cucumber Web Test case?

Ans: The following are the software required to run a Cucumber Web Test case:

  • Cucumber 

  • Ruby and its Development Kit 

  • IDE like ActiveState

  • Watir ( To simulate browser)

  • RSpec and Ansicon (if needed)

10. Name any two build management tools that can be integrated with Cucumber?

Ans: The two build management tools that can be integrated with cucumber are as follows:

11.Mention differences between BDD and TDD?

Ans:

BDD
TDD
BDD is a Behavior centered development process.
TDD is Test centered development process.
These tests are represented in a readable format using BDD steps.
These tests are represented using programming languages like JAVA, Ruby, etc.,

12. Explain Regular Expressions?

Ans: A regular expression is a pattern used to describe an amount of text. The standard Regular expression includes a single literal character.

13.Explain the test harness?

Ans: A test harness for Cucumber and RSpec enables a separate responsibility between the context setup and interacting with the browser cleaning up the step definition files.

14.What are the two files required to run a cucumber test?

Ans: Feature file and step definition file are used to run a cucumber test.

15. What is a Step Definition?

Ans: Step definition is used to map the Test Case Steps in the feature files to code. It runs the steps using Application Under Test (AUT) and verifies the outcomes against the required results. To execute step definition, it must be related to the given component in a feature.

16.What is the language used for expressing scenarios in the feature file?

Ans: Gherkin language is used for expressing scenario in feature files and ruby files, including hidden automation testing for the sequence in scenarios

17. What does a cucumber features/support file contain?

Ans: Features/support file includes ruby code. These files load before the step_definitions, which can be used for environment configuration.

18. What are the Advantages of Cucumber?

Ans: The advantages of using Cucumbers Are as follows: 

  • Cucumber Testing enhances the end-user experience

  • It helps to include business stakeholder who cannot read the code easily 

  • Allows quick and easy setup and execution

  • Style of writing tests enables easy reuse of code in the tests

19. Give an example of a behavior-driven test in plain text?

Ans: The example of a behavior-driven test in plain text is:

  • Feature: Visit the ABC page on xyz.com
  • Given: I am on xyz.com

  • Scenario: Visit xyz.com

  • When: I click on ABC page

  • Then: I should see the ABC page
