What Is Cucumber Scripting Language?

Cucumber Scripting Language is a powerful tool used for behavior-driven development (BDD). It allows software developers to write executable specifications in a simple and easy-to-understand language. In this article, we will dive deep into what Cucumber Scripting Language is all about and how it can benefit developers.

What is Cucumber Scripting Language?

Cucumber is an open-source testing framework that supports BDD. It provides a domain-specific language (DSL) known as Gherkin, which is used to write test scenarios in a human-readable format. Gherkin uses plain English with a specific syntax that makes it easy for both technical and non-technical stakeholders to understand and collaborate on the project.

Why use Cucumber?

Cucumber offers several advantages over traditional testing frameworks:

1. Collaboration: With Cucumber, business stakeholders, developers, and testers can collaborate effectively. The Gherkin syntax enables everyone involved in the project to understand the requirements and tests without diving into technical details.

2. Readable and understandable: The human-readable format of Gherkin makes it easy for anyone to comprehend the test scenarios, even those without programming knowledge.

3. Test automation: Cucumber allows you to automate your tests by writing step definitions in your preferred programming language such as Java, Ruby, or JavaScript. This way, you can easily integrate your tests into your existing testing framework.

4. Reusability: With Cucumber’s modular structure, you can reuse step definitions across multiple scenarios or even projects. This saves time and effort as you don’t have to rewrite the same code repeatedly.

5. Living documentation: Cucumber tests act as living documentation for your application’s behavior. By reading the feature files written in Gherkin, you can understand how the application is expected to behave.

Getting Started with Cucumber

To start using Cucumber, you need to follow a few steps:

1. Install Cucumber: Depending on your programming language, you can install Cucumber using package managers like npm (for JavaScript), Bundler (for Ruby), or Maven (for Java). Create a feature file: Feature files have a “.feature” extension and contain test scenarios written in Gherkin syntax. Each feature file represents a specific functionality of your application. Write scenarios: Scenarios are written in Gherkin syntax and describe the behavior of your application from an end-user perspective. Each scenario consists of multiple steps. Implement step definitions: Step definitions are written in your preferred programming language and map each step of the scenario to executable code. Run tests: Once you have implemented the step definitions, you can run your tests using the Cucumber command-line interface or by integrating it into your continuous integration system.

Gherkin Syntax

Gherkin uses a specific syntax for writing test scenarios:

  • Feature: Describes the feature being tested.
  • Scenario: Represents a specific test scenario.
  • Given/When/Then: Steps that define the preconditions, actions, and expected outcomes of the scenario.
  • And/But: Additional steps used to combine multiple conditions or actions within a scenario.

Here’s an example of a simple Gherkin scenario:

Feature: Login
  As a user
  I want to log in to my account
  So that I can access my profile
  Scenario: Successful login
    Given I am on the login page
    When I enter valid credentials
    Then I should be redirected to my profile page

In this example, the scenario describes the steps for a successful login.


Cucumber Scripting Language, with its Gherkin syntax, provides a powerful framework for behavior-driven development. It promotes collaboration, readability, and reusability of tests, making it an ideal choice for teams practicing BDD.

By adopting Cucumber, you can bridge the gap between technical and non-technical stakeholders and ensure that your application meets the desired behavior. So why not give Cucumber a try in your next project?
