End-to-End Testing

Cypress can be used to perform end-to-end testing on web applications. The code sample demonstrates how to visit a webpage, interact with elements, and assert that the actions have the expected outcome.

cy.visit('https://example.com')
  .get('.new-todo')
  .type('Learn Cypress{enter}')
  .get('.todo-list li')
  .should('have.length', 1)

Integration Testing

Cypress can also be used for testing React components by mounting them in the test runner. The code sample shows how to mount a component, simulate user interaction, and assert the result.

cy.mount(<MyComponent />)
  .get('button').click()
  .get('.result').should('contain', 'Clicked')

API Testing

Cypress can perform API testing by sending HTTP requests and asserting the responses. The code sample demonstrates how to send a POST request to an API endpoint and validate the response.

cy.request('POST', '/api/items', { name: 'Cypress' })
  .then((response) => {
    expect(response.body).to.have.property('id')
    expect(response.body).to.have.property('name', 'Cypress')
  })

Visual Testing

With the help of plugins, Cypress can be extended to perform visual regression testing. The code sample shows how to take a snapshot of an element and compare it to a baseline image for visual differences.

cy.visit('https://example.com')
  .get('.important-element')
  .matchImageSnapshot()
