BDD Cucumber Interview Questions And Answers

What is a cucumber?
Cucumber is a tool based on Behavior Driven Development (BDD) framework which is used to write acceptance tests for the web application. It allows the automation of functional validation in an easily readable and understandable format to Business Analysts, Developers, Testers, etc. The language that Cucumber understands is called Gherkin. It is written in a Ruby programming language.

What are the advantages of a Cucumber?
Advantages of Cucumber:

  • You can involve business stakeholders who can not code.
  • End-user experience is the priority.
  • High code reuse.

Explain What Is BDD (Behavior Driven Development)?
BDD or Behaviour-driven development is a process of developing software based on TDD (Test Driven Development) which focuses on the behavioral specification of software units.

What is the profile in cucumber?
We can create profiles to run specific features and step definitions. We can use the following command to execute a cucumber profile.
Syntax: cucumber features -p Ex: cucumber features -p regression

What is the cucumber.yml file?
In the cucumber.yml file, we will create profiles.

What Is Support, Env.RB, And Hooks.RB?
Support is a folder where we can setup cucumber related support.
Env.rb file will be used to load the required libraries for scenario execution
hooks.rb we will add hooks like before, after, beforeStep, and afterStep hooks.

Explain features in Cucumber?
A feature can be defined as a standalone unit or functionality of a project. Let’s take a very common example of a social networking site.

How does the feature of this product/project look like?
Few basic features can be determined as –

  • Create and remove the user from the social networking site.
  • User login functionality for the social networking site.
  • Sharing photos or videos on a social networking site.
  • Sending a friend request.
  • Logout.

Explain the parts/keywords of the feature file?
A simple feature file consists of the following keywords/parts –

  • Feature- Name of the feature under test.
  • Description (optional)- Describe the feature under test.
  • Scenario- What is the test scenario.
  • Given- Prerequisite before the test steps get executed.
  • When- the Specific condition which should match to execute the next step.
  • Then- what should happen if the condition mentioned WHEN is satisfied.

Explain What Is Scenario Outline In Feature File?
Scenario Outline: the Same scenario can be executed for multiple sets of data using the scenario outline. The data is provided by a tabular structure separated by (II).

What Is Step Definition In Cucumber?
A step definition is the actual code implementation of the feature mentioned in the feature file.

What is the cucumber dry run?
The dry run is used to compile cucumber feature files and step Definitions. If there are any compilation errors it will show when we use dry run
Ex: Cucumber features –dry-run

What are the two files which you need to run a Cucumber test scenario?
If you want to execute a test, then make sure it has the following two files.

  • A feature file.
  • A step definition file

What Are Before, After, BeforeStep, And AfterStep Hooks?

  • Before: execute before the feature file execution
  • After: executes after the feature file execution
  • BeforeStep: executes before each step execution
  • AfterStep: executes after each step execution

Explain What Is Test Harness?
A test harness for cucumber and rspec allows for separating responsibility between setting up the context and interacting with the browser and cleaning up the step definition files.

What Are Cucumber Tags? Why We Use The Tags?
Tags are used to filter the scenarios. We can tag the scenarios and we can execute the scenarios based on tags, We can add tags to scenarios with @ We can use the following command to execute cucumber-tagged scenarios.

cucumber features -t @
Ex: cucumber features -t @test

Explain What Is Regular Expressions?
A regular expression is a pattern describing a certain amount of text. The most basic regular expression consists of a single literal character.

What are the prereqs for building a Selenium Cucumber automation framework?
You might like to consider the following facts while creating a productive and scalable test framework:

  • Identify the type of application you are going to test. Is it a Web app, supports mobile devices, or runs on a desktop.
  • Would it require backend testing? e.g. Databases or SDK.
  • Do you need to test the app for internationalization?
  • It must have a report which can help you trace a failure with minimum efforts.
  • It must support the auto-generation of parametrization tests.
  • Have a config file to define any setup-related settings or global properties.
  • Apply abstraction at every level to separate the functionality.

How to integrate Cucumber with Selenium Webdriver?
It’s the most obvious interview question which you must know. And it’s better if you give a step-by-step reply to the interviewer. It’ll leave a positive impression on him as you’ll show the depth of your knowledge.

  • Cucumber is a testing framework to run acceptance test cases. It creates scripts using the BDD approach.
  • It makes use of a feature file that describes the test cases in plain text format.
  • Here you write tests in simple English. And later use the Selenium Webdriver to run the test scripts.
  • To start Cucumber with Selenium, first of all, you require creating a Maven project in Eclipse.
  • In the Maven’s POM file, you add the dependency which brings the support of annotations
  • Similarly, you can introduce the Selenium dependency into the above project. Alternatively, you can download the latest version of the Selenium standalone jar from their website. And then, add it to your project as an external jar file.

Explain JUnit Runner?
To run the specific feature file it uses standard JUnit Runner and specifies tags in @Cucumber. Options. Multiple tags can be given by using comma-separated. Here you can specify the path of the report and the type of report you want to generate.
Example of Junit Runner:

import cucumber.api.junit.Cucumber;
import org.junit.runner.RunWith;
Public class JUnitRunner {}

Are there any readymade Selenium-Cucumber frameworks available?
Yes, there are a few we are listing down below. Though, we recommend building one of your own as it gives you more freedom.

  • Selenium-Cucumber framework for testing the web and Android apps.
  • Another one is an acceptance testing framework using Cucumber and Selenium WebDriver.

What is ORM in Rails?
ORM tends for Object-Relationship-Model, which means that your Classes are mapped to a table in the database, and Objects are directly mapped to the rows in the table.

List out some of the main differences between Jbehave and Cucumber?
However, the Cucumber and Jbehave share the same perspective, but there are few key differences.

  • Jbehave is Java-based and Cucumber is Ruby-based.
  • Jbehave is story-driven whereas Cucumber is feature-driven.

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

  • Ruby and its Development Kit
  • Cucumber
  • IDE like ActiveState
  • Watir ( To simulate browser)
  • Ansicon and rspec (if required)

What are the steps to generate a report in Cucumber?
We run the following command to produce HTML reports.
cucumber .feature –format HTML –out report.html –format pretty

What is the right way to execute a specific scenario from the feature file?
We can select the target scenario from a feature file by providing its line number.
cucumber features/test.feature:10 –format HTML > testfeature.html

What is Gherkin, and what is its primary purpose?
Gherkin is a language used to write executable specifications in a human-readable format. Its primary purpose is to define the behaviour of a software application in a way that non-technical stakeholders can understand.

What are the key components of a Gherkin file?
Gherkin files typically consist of feature, scenario, scenario outline, Given-When-Then steps, and tags.

Explain the structure of a Gherkin scenario.
A Gherkin scenario consists of three parts: Given, When, and Then. “Given” sets up the initial state, “When” describes the action taken, and “Then” specifies the expected outcome or result.

What is the purpose of tags in Gherkin?
Tags are used to label scenarios or features, making it easier to organize and filter them. They can be used for various purposes, such as grouping related scenarios or marking scenarios for specific test runs.

What are scenario outlines, and when do you use them?
Scenario outlines are used when you have a scenario that follows a similar structure but with different input values. They are a way to create data-driven tests in Gherkin.

Explain the difference between “Background” and “Scenario” in Gherkin.
“Background” is used to define steps that are common to all scenarios in a feature file, while “Scenario” is used to define a specific test case or scenario.

How do you write comments in a Gherkin file?
Comments in Gherkin are written with the “#” symbol at the beginning of a line.

What are the best practices for writing effective Gherkin scenarios?
Some best practices include using clear and concise language, avoiding technical details, and focusing on the behaviour being tested. Scenarios should be independent and not rely on the order of execution.

Explain how Gherkin scenarios are transformed into executable tests.
Gherkin scenarios are typically associated with a test automation framework like Cucumber, which provides step definitions that map Gherkin steps to actual code. These step definitions are implemented to execute the tests.
