Web-based automation testing using Behaviour Driven Development is supported by the open-source Cucumber Framework in Selenium. The first version of the tests is an easy scenario that explains the anticipated system behaviour from the viewpoint of the user.

Cucumber is written in Ruby and is mostly used for acceptance tests; the tests are written in the human-readable, non-technical language of Gherkin.

The requirements for setting up Cucumber and Selenium are:

We need to install the Eclipse IDE for Java.
Then we need to configure the Maven Project in Eclipse
We need to install the Selenium WebDriver and configure it with our Eclipse.
We need to install the TestNG plugin and configure it with Eclipse.
Finally need to install the Cucumber plugin and configure the plugin with Eclipse

For a seamless interaction, the Cucumber-java, Cucumber-junit, and Cucumber-core jar versions should match.
Debugging and identifying the problem can be aided by including an after hook in the code to take screenshots in the event that the test fails.
To organise tests according to tag definitions, use tags. This is useful when it’s not necessary to run every test once. These tests can be executed only when necessary and identified with tags. Time, system processing power, and resource consumption are all reduced as a result.
Avoid using technicalities that are too technical and concentrate on the needs of the business.
Use parameterization to make step definitions more generic and reusable.
Be clear of the lengthy scenarios that assess a variety of unconnected aspects.
To organise situations according to features, priorities, or execution contexts, use tags.
Need to Maintain the test data in external files or databases and keep it apart from the test logic.
You can automate testing and deployment processes by integrating Cucumber tests into your CI/CD pipeline.
Test code should be reviewed and modified frequently to increase readability, maintainability, and efficiency.

				
					Example Step Definitions (LoginSteps.java):
import io.cucumber.java.en.Given;
import io.cucumber.java.en.When;
import io.cucumber.java.en.Then;

public class LoginSteps {

    @Given("^I am on the login page$")
    public void navigateToLoginPage() {
        // Code to navigate to the login page
    }

    @When("^I enter my username and password$")
    public void enterCredentials() {
        // Code to enter username and password
    }

    @When("^I click the login button$")
    public void clickLoginButton() {
        // Code to click the login button
    }

    @Then("^I should be logged in successfully$")
    public void verifySuccessfulLogin() {
        // Code to verify successful login
    }
}

In conclusion, the Cucumber framework in Selenium provides a powerful combination of testing capabilities and collaboration tools that can greatly enhance the efficiency and effectiveness of your test automation projects. By leveraging the BDD approach, Cucumber allows for clear communication between stakeholders and team members, resulting in more reliable and maintainable automated tests. Whether you are a beginner or an experienced Selenium user, incorporating the Cucumber framework into your testing strategy can bring significant benefits in terms of productivity and quality. Embrace Cucumber in your Selenium test automation efforts and witness the positive impact it can have on your software development lifecycle.
