Introduction

Cucumber is a testing approach/tool that supports Behavior Driven Development (BDD). It provides a way to write tests that anybody can understand, regardless of their technical knowledge.

It explains the behavior of the application in a simple English text using Gherkin language.

Steps by step approach to write automation tests using Cucumber

Prerequisite

In this newsletter, we will be using:

Java as the programming language
TestNG as the assertion framework
Maven as the build automation tool
Selenium WebDriver as the browser automation tool
Cucumber as BDD tool
Eclipse as the IDE

Step 1: Add Cucumber Dependency in Pom.xml

Cucumber doesn’t actually interact with the browser and performs actions on the website under test. Interacting with the website is the action that is performed by Selenium WebDriver. Due to this reason, you will need to add Cucumber as well as Selenium dependency in Pom.xml

Add “cucmber-java” and “cucumber-testng” dependency in the pom.xml.

Step 2: Install Cucumber Plugin from Eclipse Marketplace

The next step is to install Cucumber on your Eclipse. For that, you need to go to Help -> Eclipse Marketplace -> Search Cucumber and install Cucumber on your eclipse. Below snapshot depicts the same.

Step 3: Create a feature file and add scenarios

Once cucumber is configured, next step is to setup feature file. Create feature file as shown below.

Once Feature file is created, we can write scenarios as shown below.

Step 4: Implement the scenario using step definitions file

Step definition files contain the actual code implementation of the steps mentioned in the feature files. They map Gherkin steps to executable code. Each step in the feature file should have a corresponding step definition method.

Step 5: Write runner class and execute the class

TestNG will execute Cucumber scenarios based on the specified options in the @CucumberOptions annotation in your runner class. Here glue represents the step definitions file path.

Once we execute test runner file, here is the output we get.

Execute Tests using Jenkins

Step 1: To execute Tests using Jenkins, need to create new Item here in Jenkins. Here I have selected Free Style Project as shown below.

Step 2: Configure the Project created in Jenkins and add repository. Here I have added custom repository as shown below. Also add the maven command “mvn test” in the build section.
