Key features include: 1) Automatic waiting and retry-ability, 2) Real-time reloads, 3) Consistent results due to automatic waiting, 4) Time travel and debugging capabilities, 5) Network traffic control, 6) Screenshots and videos of test runs, 7) Cross-browser testing support, 8) Built-in assertion library, 9) Stubbing and spying on network requests, 10) Interactive test runner.
What is the Cypress Test Runner?
The Cypress Test Runner is an interactive interface that allows you to see commands as they execute, view the application under test, and inspect the DOM. It provides features like time travel, real-time reloads, and debugging tools. The Test Runner shows the command log, application preview, and detailed error messages when tests fail.
How do you install and initialize Cypress in a project?
Cypress can be installed using npm: 'npm install cypress --save-dev'. After installation, initialize it using 'npx cypress open' which creates the cypress directory with example specs and configuration. The configuration file (cypress.config.js) can be customized for project-specific settings.
What is the structure of a basic Cypress test?
A basic Cypress test uses describe() blocks for test suites and it() blocks for individual tests. Tests typically follow the pattern: visit a page, get an element, interact with it, and make assertions. Example: describe('My Test Suite', () => { it('performs an action', () => { cy.visit('/'); cy.get('button').click(); cy.contains('Result').should('be.visible'); }); });
What are Cypress commands and how do they work?
Cypress commands are chainable methods that perform actions, assertions, or retrieve elements. They are asynchronous but handle promises automatically. Commands follow a sequential order and include automatic retry-ability and waiting. Common commands include cy.visit(), cy.get(), cy.click(), cy.type(), and cy.should().
How does Cypress handle asynchronous operations?
Cypress automatically handles asynchronous operations through its command queue. Commands are executed sequentially, and Cypress automatically waits for commands to complete before moving to the next one. It includes built-in retry-ability and timeout mechanisms, eliminating the need for explicit waits or async/await syntax.
What are aliases in Cypress and how are they used?
Aliases are references to elements, routes, or values that can be reused throughout tests. They are created using cy.as() and referenced using @alias syntax. Aliases help reduce code duplication and make tests more maintainable. Example: cy.get('button').as('submitBtn') and later cy.get('@submitBtn').click().
How do you handle assertions in Cypress?
Cypress includes Chai assertions and extensions through .should() and .expect(). Assertions automatically retry until they pass or timeout. Common assertions include checking visibility, text content, element states, and DOM properties. Example: cy.get('element').should('be.visible').and('contain', 'text').
What is the difference between cy.get() and cy.find()?
cy.get() searches for elements in the entire DOM and starts a new command chain. cy.find() searches for elements within the previous subject's DOM and continues the existing chain. cy.get() is used for initial element selection, while cy.find() is used for finding nested elements.
