7. How do you write tests in Cypress?

Tests in Cypress are written using JavaScript. You can write a test by creating a new spec file in the ‘cypress/integration‘ directory and writing your test code using Cypress commands.

8. What are Cypress Commands?

Cypress commands are used to interact with elements on a web page, such as clicking buttons, typing text, and making assertions

9. What is the command to launch a URL?

14. How do you handle test data in Cypress?

You can use fixtures in Cypress to handle test data. Fixtures are files that contain static data such as JSON or CSV files that can be used in your tests.

15. What is the command to find if an element is displayed on a screen?

cy.get('selector').should('be.visible');

16. What is the command to verify if a checkbox/radio is selected?

17. What is the command to verify if a button is enabled?

cy.get('button').should('not.be.disabled');

18. What is the command to verify if a button is disabled?

cy.get('button').should('be.disabled');

19. What is the command to verify if a textbox is editable?

cy.get('input[type="text"]').should('not.have.attr', 'readonly');

20. What is the command to take a screenshot of an element?

cy.get('selector').screenshot();

21. What are the different commands used to select a dropdown list?

cy.get('select').select('OptionText'); //SelectByVisisbleText

cy.get('select').select(2); //SelectByIndex

cy.get('select').select('OptionValue'); //SelectByValue

22. What are the different commands used to deselect a dropdown list?

Cypress doesn’t have a built-in method for deselecting options from a dropdown like the deselect method in Selenium. However, you can achieve a similar effect by reselecting the desired options

23. Name any 4 commonly used Assertions in Cypress?

should('exist'): Asserts that the element exists in the DOM.

should('be.visible'): Asserts that the element is visible.

should('have.text', 'expectedText'): Asserts that the element has the expected text.

should('have.attr', 'attributeName', 'expectedValue'): Asserts that the element has the expected attribute value.

24. What are the different navigation commands?

cy.visit('https://letzdotesting.com');

cy.reload();  // Refresh your current page

cy.go('back'); // Takes one page backward based on browser's history

cy.go('forward'); // Takes one page forward based on browser's history

cy.go(-1); // Navigate to previous url in browser's history

cy.go(1); // Navigate to next url in browser's history

25. What is the command to right click?

cy.get('img').invoke('attr', 'src').should('eq', 'image.jpg');

30. How do you mock network requests in Cypress?

You can mock network requests in Cypress using the cy.route() command. For example, cy.route('GET', '/api/users', 'fixture:users.json') mocks a GET request to the ‘/api/users’ endpoint.

31. Write code to close the entire browser.

cy.window().then(win => win.close());

32. How do you handle asynchronous code in Cypress?

Cypress automatically handles asynchronous code using its built-in queuing system. You can use cy.then() to chain commands together.

33. What are the different types of waits available in Cypress?

In Cypress, there are several types of waits available to handle different synchronization scenarios in your tests. Here are the main types of waits:

Implicit Wait: Cypress doesn’t have an implicit wait like Selenium. Instead, Cypress automatically waits for commands and assertions to pass before moving on to the next command.

Explicit Wait: Cypress provides explicit wait options using commands like cy.wait() and .should(). These commands can be used to wait for specific conditions before continuing with the test.

Timeouts: Cypress has default timeout settings for various commands and assertions. You can also specify custom timeouts using the .timeout() command to wait for a specific amount of time for a command or assertion to pass.

Retry-ability: Cypress automatically retries failed commands and assertions. You can configure the number of retries using the retries option in the configuration file.

Waiting for Network Requests: Cypress provides commands like cy.wait() and .should() that can wait for network requests to complete before continuing with the test.

Overall, Cypress’s approach to waiting is more dynamic and efficient compared to traditional explicit and implicit waits in other testing frameworks.

34. How to handle iframes in Cypress?

cy.iframe().find('button').click()

35. Name any three testing frameworks that can be integrated with Cypress?

36. How do you handle timeouts in Cypress?
