Behavior Driven Development (BDD) is an approach used to create test cases in the software development process. The popularity of BDD is steadily rising across the companies with plenty of opportunities for skilled ones. People interested in getting started with their careers in BDD will need a lot of practical knowledge and know what the industry expects from them. Mindmajix BDD Interview Questions cover all such frequently asked questions from our alumni trainees, who have attended interviews after completing BDD Training.
So, let’s start Behavior Driven Development (BDD) Interview Questions one by one in detail.

Behavior-driven development (BDD) is developing software based on Test Driven Development (TDD) that focuses on the behavioral specification of software testing units.
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.
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>
The Two main files used to run a Cucumber test scenario are
A step definition is the actual code implementation of the feature mentioned in the feature file.
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.
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.”
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.
The following are the software required to run a Cucumber Web Test case:
Ruby and its Development Kit
IDE like ActiveState
Watir (To simulate browser)
RSpec and Ansicon (if needed)
The two build management tools that can be integrated with cucumber are as follows:
The following are the difference between BDD and 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.,|
A regular expression is a pattern used to describe an amount of text. The standard Regular expression includes a single literal character.
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.
Feature file and step definition file are used to run a cucumber test.
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.
Gherkin language is used for expressing scenario in feature files and ruby files, including hidden automation testing for the sequence in scenarios
Features/support file includes ruby code. These files load before the step_definitions, which can be used for environment configuration.
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
The example of a behavior-driven test in plain text is:
Given: I am on xyz.com
Scenario: Visit xyz.com
When: I click on ABC page
Then: I should see the ABC page
