Setting Up Cypress
1. Introduction
Cypress is a powerful JavaScript-based end-to-end testing framework that allows developers to write tests for web applications.
Key features include:
- Real-time reloads
- Automatic waiting
- Network traffic control
2. Installation
To install Cypress, follow these steps:
- Ensure you have
Node.js
installed on your machine. - Navigate to your project directory in the terminal.
- Run the following command:
- Open Cypress using:
npm install cypress --save-dev
npx cypress open
3. Configuration
Cypress can be configured using the cypress.json
file located in the root of your project. Here’s an example configuration:
{
"baseUrl": "http://localhost:3000",
"viewportWidth": 1280,
"viewportHeight": 720
}
4. Writing Tests
To write a test, create a file in the cypress/integration
directory. Here’s a simple test example:
describe('My First Test', () => {
it('Visits the Kitchen Sink', () => {
cy.visit('https://example.cypress.io');
cy.contains('type').click();
cy.url().should('include', '/commands/actions');
cy.get('.action-email').type('fake@email.com').should('have.value', 'fake@email.com');
});
});
5. Best Practices
Consider the following best practices while using Cypress:
- Keep tests isolated
- Use fixtures for test data
- Group tests logically
