Things You Should Know About Cucumber Testing Tool

There is no question, Selenium is one of the phenomenal tools in the field of automation testing. However, it might be difficult for a non-technical person to understand its functioning because of the complexity of code. To make it easier, Cucumber comes into play that converts the complex code into simple plain text. But exactly how it does do? Let us understand about cucumber and software development model it follows.

Cucumber is a testing framework that supports Behavior Driven Development (BDD). It allows us to define application behavior in a simple English text using a language called Gherkin. That’s why anyone can understand even if they don’t have any technical knowledge. In general, BDD is a technique where specifications or test cases are written in simple English sentences. It acts as a bridge among the Business Analyst and software Engineer; Developers and Manual testers. This in order, helps non-technical members to easily check out the flow and collaborate more in the process of software development.

Why Need of Cucumber in Testing Framework?

  • Open-source tool; so it’s free to use.
  • Can write scripts in multiple languages like Jave, Python, .NET, Ruby and many more.
  • Integrates with Selenium, Watir, Ruby on Rails and other web-based testing tools.
  • Enhance communication between technical and non-technical members in the same project.
  • Include business stakeholders who are unable to read code easily.
  • Concentrate on End-user experience.
  • Efficient tool for testing.
  • Easy setup and implementation.
  • Code re-usability due to simple test script architecture.

Let Us Discuss The Basics Of Cucumber

1. Features File (Entry point to Cucumber tests)

It is used to write automation steps for acceptance tests and used as a live document. All the feature files end with feature extension. You can create a multiple number of features files as needed, but each feature should have one feature file for an organized structure.

A simple feature file take account of the following keywords/parts:

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

2. Step Definition

Step definition help to maps the test case steps in the feature files that are introduced by When/ Given/Then. It performs the steps on Application Under Test and verifies the results against expected outcomes. It is defined in ruby files under "features/step_definitions/*_steps.rb".

An interpretation chased by the pattern is utilized to attach the step definition to every matching step and the code. It will also check what cucumber will carry out when it checks with Gherkin Step. Cucumber identifies the step definition file using the Glue code in cucumber options.

3.Test Runner file

It defines the location of step definition and mainly gives every metadata information needed for test execution. It employs ‘@RunWith()’ annotation from the JUnit framework for execution. Secondarily you can use ‘@CucumberOptions’ annotation to define the location of feature files, step definitions location through glue, what reporting integrations to make and many more.

4.JUnit Runner

JUnit is an open-source unit testing framework for the Java programming language. When we run the JUnit runner class, it inspects the Gherkin feature file and executes the functions that are written in the step definition file following feature file statements. Next, it will merge the test case results and form the test report in the specified format such as HTML, JSON.

Points To Consider When Start With Cucumber Tool

  • Asses automation tests as important as a real project.
  • The code must follow coding practice, convention and so on.
  • A proper editor tool should be considered. It must help to debug and edit features files in standard text format. RubyMine (commercial editor), Aptana( free editor) and Katalon Studio are examples that entirely support BDD-based Cucumber.
  • Create features file an actual communication layer in which you can store received tests as well as format test data.
  • Make sure domain business logic is not contained.


If you want to execute Web UI and web service testing so that your Agile software projects should be operated successfully, Cucumber is the best option for you. It is easy to understand, readable and involves multiple business functionality. Whether you are searching to take control of a legacy project that’s falling apart without tests, or want to adopt BDD in a fresh project, you can hire our experienced tester team that can provide you both immediate as well as long-term benefits. We use cucumber tool that help to run automation tests on a wide-ranging testing needs from backend to frontend. Moreover, Cucumber creates deep connections among members of the testing team which is hardly found in other testing frameworks.
