In this comprehensive guide, we’ll not only walk you through an invaluable Cypress cheat sheet but also discuss the essential commands, tips, and best practices to enhance your testing workflow. By the end of this article, you’ll be able to download a meticulously crafted Cypress cheat sheet in PDF format to keep handy for your testing needs.
Why Cypress?
Before we jump into the cheat sheet, let’s briefly discuss why Cypress has become a go-to tool for end-to-end testing:
- Fast and Reliable: Cypress is renowned for its speed and reliability. Unlike other testing frameworks that rely on Selenium WebDriver, Cypress runs directly in the browser, offering a faster and more reliable testing experience.
- Real-Time Reloads: Cypress automatically reloads your tests as you make changes, allowing for rapid development and debugging.
- Powerful Debugging Tools: With built-in debugging capabilities, Cypress makes it easier to pinpoint issues with detailed error messages and stack traces.
Getting Started with Cypress
Before exploring the cheat sheet, make sure Cypress is properly installed and configured in your project environment. If you haven’t done so already, follow these steps:
1. Install Cypress: Run the following command to install Cypress as a dev dependency in your project:bashCopy code
npm install cypress --save-dev
2. Open Cypress: Once installed, open Cypress with:
npx cypress open
3. Create Test Files: Cypress will automatically generate a folder structure. You can start creating test files in the cypress/integration
directory.
The Cypress Cheat Sheet: Essential Commands
Here’s a detailed Cypress cheat sheet covering essential commands for both beginners and intermediate users.
1. Basic Commands
Visit a URL
cy.visit('https://example.com')
Click an Element
cy.get('.button-class').click()
Type into an Input Field
cy.get('input[name="username"]').type('myusername')
Assert Text
cy.get('.text-class').should('contain', 'Expected Text')
Check Visibility
cy.get('.element-class').should('be.visible')
Wait for an Element
cy.get('.loader').should('not.exist')
2. Advanced Commands
Chain Commands
cy.get('.form').submit()
Mock API Response
cy.intercept('GET', '/api/data', { fixture: 'data.json' }).as('getData')
Select Dropdown Option
cy.get('select[name="options"]').select('Option 1')
Drag and Drop
cy.get('.draggable').trigger('mousedown', { which: 1 })
cy.get('.droppable').trigger('mousemove').trigger('mouseup', { force: true })
Check Element Count
cy.get('.item-class').should('have.length', 3)
Take Screenshot
cy.screenshot('screenshot-name')
3. Debugging and Troubleshooting
Pause Test Execution
cy.pause()
Debug a Command
cy.get('.element-class').debug()
Set a Debugger
cy.get('.element-class').click().then(() => {
debugger
})
Use .then()
for Custom Assertions
cy.get('.element-class').then($el => {
expect($el).to.have.lengthOf(1)
})
4. Best Practices
- Write Clear and Concise Tests: Ensure your test cases are straightforward and easy to understand. Avoid complex logic within tests.
- Use Aliases: Use
cy.intercept
andcy.get
with aliases for more readable and maintainable code.
cy.intercept('GET', '/api/data', { fixture: 'data.json' }).as('getData') cy.wait('@getData')
- Clean Up After Tests: Ensure your tests do not leave behind any data or state. Use
cy.clearCookies()
andcy.clearLocalStorage()
if necessary. - Group Tests Logically: Organize your test cases into logical groups to improve readability and maintainability.
describe('Login Tests', () => {
it('should log in with valid credentials', () => {
// Test code here
})
})
