Introduction to Cucumber Interview Questions and Answers
Cucumber is an automation testing tool used by Testers to execute acceptance tests in Behavior Driven Development (BDD) approach. This tool was developed using the Ruby programming language and was licensed by MIT. The test cases defined by Cucumber use Gherkin language which is a human-readable, non-technical and simple syntax of its language is used for documentation.
Cucumber avoids more technical stack and will be easier to test without any programming skills. All the test cases can be written in plain English language.
Preparing for a job interview in Cucumber. I am sure you want to know the most common Cucumber Interview Questions and answers that will help you crack the Cucumber Interview with ease. Below is the list of top Cucumber Interview Questions and answers at your rescue.
Part 1 – Cucumber Interview Questions (Basic)
This first part covers basic Cucumber interview questions and answers
1. What is Cucumber and explain it?
Cucumber is an automation testing framework used to test the software applications easily without any programming skills and reduces the effort and increases the quality of testing. This is an open source tool and supports plain English language specifications for the testing requirements. Other technical methods to use the programming languages are Java, .NET and other platforms. The cucumber specifications contain different scenarios and examples.
2. What are the different scenarios in the Cucumber tool?
The different scenarios used in Cucumber are 1. Given (some initial context) 2. When (an event occurs) 3. Then (ensure some outcomes). Scenarios will be initially described in natural language. The scenarios, when added with the definition of steps, will be called as Scenarios. The scenarios can be run individually or can be integrated with other features to test the integration functionalities. The scenarios in the Cucumber will be written by Gherkin syntax which is a language for writing Cucumber automation test specifications.
Let us move to the next Cucumber interview question.
3. What are the features in Cucumber?
This is the most common cucumber interview questions. A feature can be defined as a unit or functionality or part of a project which is an independent functionality of the project. A feature contains a group of scenarios which are to be tested as a feature. There are two parts in a feature in Cucumber tool which is called feature files having scenarios in it and the feature files containing automation steps or procedure to be executed. An example of a feature can be a login functionality of a website or chat functionality of a website, a news feed of a website etc.
4. What is BDD and how Cucumber complies with BDD?
BDD is a Behaviour Driven Development approach of software development process where Cucumber works in BDD way of approach. The tests in BDD are written in a human-readable format and understandable which are easier to implement. The BDD tests are non-programming and easier to write. Behavior Driven Development process is highly efficient and useful in resolving complex solutions and requirements in the project to handle smoothly.
5. What is a feature file in Cucumber?
A feature file in Cucumber is a starting point of the Cucumber tests execution. This is the basic cucumber interview questions. The feature files exist in the feature folder. To add a feature file in the project, the scenario or feature to be automated has to be identified before, then feature file is added and then test runner class will be created. Now step definitions have to be linked with feature files. The scenario steps will then be executed during automation. In this file, the description of the tests will be available in the descriptive language. A feature file can have a single or multiple scenarios but normally it contains a group of scenarios. The feature file format will be like file_name. a feature where a single file contains a single feature
Part 2 – Cucumber Interview Questions (Advanced)
Let us now have a look at the advanced Cucumber Interview Questions.
6. What are the different keywords used in feature file?
The different keywords used in the feature file are Feature, Background, Scenario, Scenario Outline, Given, When, Then and But. The keyword used to represent a feature in a feature file is Feature. The feature file should be mentioned with a brief description to ensure the best practice standards. A Feature is the Name of the feature that is under test, Description is about the feature under test, Scenario is about What the test scenario is, Given is Prerequisite before the test steps get executed, When is a specific condition that matches in order to execute the next step, Then is about What happens if the condition in WHEN is satisfied
7. What is Scenario Outline in Cucumber?
This is the most asked cucumber interview questions. A scenario outline replaces an identifier with the actual value from the table. Each row can be considered as a scenario. A feature file is more time taking a task and is more error-prone in testing. The same feature file can be reduced to less number of lines for execution in the scenario outline feature to increase the efficiency and decreases the runtime.
Let us move to the next Cucumber Interview Questions.
8. What is a profile in Cucumber?
Cucumber profiles can be created in the project to make the configurations. A default profile will always be available in the project. The configuration file will be like cucumber.yml file where the profiles will be configured. The data types and parameter types can be configured using the type registry. The profiles or default profiles will not be available in Java.
9. Which language is used to specify the scenarios in Cucumber?
The language used to specify a scenario in feature file is Gherkin language and Ruby programming language to implement the automation tests scripts execution. Gherkin language provides writing features and the syntax is easier to read and generate the documentation for automation tests. Gherkin is a line-oriented language.

10. What are the advantages of Cucumber?
The cucumber tests are written based on the user’s point of view. The scenarios in the testing will be covered by all the team members, product owners, business analysts, test analysts, developers etc., to implement the automation efficiently. The code reusability can be achieved. The primary advantage of Cucumber is its support of Behaviour Driven Development approach in testing. This tool helps in eliminating the gap between different technical and non-technical members of the team. It provides collaborative and inclusion with the team. Streamlining and artifacts will be in line with the project expectations and requirements. Adaptability will be high in case of major changes to the functional or behavioral requirements.
