End to end testing using Cypress

End-to-end testing is a software testing technique that verifies the functionality and performance of an entire software application from start to finish by simulating real-world user scenarios and replicating live data.

Setting Up Cypress for Automated Testing in Node.js Projects

Cypress is a powerful tool for end-to-end testing of web applications. Here’s a step-by-step guide to getting started with Cypress in your Node.js projects:

1. Install Node.js
Ensure you have Node.js installed on your computer. You can download it from the official Node.js website and follow the installation instructions.

2. Install Cypress Globally
Open your terminal or command prompt and run the following command to install Cypress globally:

npm install -g cypress

3. Install Cypress for Development
Navigate to your project directory in the terminal and run the following command to install Cypress for development:

npm install cypress - save-dev

4. Check Cypress Version
Verify that Cypress is installed correctly by checking its version:

cypress — version

5. Open Cypress
To open Cypress and set up your testing environment, run the following command:

npx cypress open

This command will launch the Cypress Test Runner, where you can write and run your tests.

6. Run Cypress Tests
Once Cypress Test Runner is open, you can run your Cypress tests using the following command:

npx cypress run

This command executes your tests in headless mode, providing you with test results and insights.

Here are some examples of tests:
