Steps to Build a BDD Framework with Cypress
Run npm init -y, this will create a package.json 01 02
Install Cypress and any necessary dependencies. You can install Cypress via npm by running the following command in your terminal:
npm install cypress --save-dev
we are not able to use the BDD approach directly in cypress. We require the following dependencies: 03
npm install -D cypress @badeball/cypress-cucumber-preprocessor
npm install -D @bahmutov/cypress-esbuild-preprocessor npm install -D @esbuild-plugins/node-modules-polyfill
Write your feature files in Gherkin syntax. Feature files describe the functionality of your application in plain English, using Given-When-Then syntax. For example:
Feature: Login functionality
As a user
I want to be able to log in to the application
So that I can access my account
Scenario: Successful login
Given I am on the login page
When I enter valid credentials
And I click the login button
Then I should be redirected to the dashboard page
Create step definitions for your feature files. Step definitions are JavaScript functions that map to the steps in your feature files. They use Cypress commands to interact with the application and make assertions about its behavior. For example:
import { Given, When, Then } from "cypress-cucumber-preprocessor/steps";
Given("I am on the login page", () => { cy.visit("/login");
When("I enter valid credentials", () => { cy.get("#username").type("myusername"); cy.get("#password").type("mypassword");
When("I click the login button", () => { cy.get("button[type='submit']").click();
Then("I should be redirected to the dashboard page", () => { cy.url().should("include", "/dashboard");
