Cypress Interview Questions for Experienced

16) How to execute a cypress hello world test script?

After installing Cypress, a folder named integration will be created in which you may construct your first spec file in typescript or JavaScript.

Your spec file should include a describe() and/or it() block. Inside this block, use the cypress command to run the test.

17) In Cypress, how can you create suites?

We may construct a describe() block. The described block serves as a suite, and each test may be built as a separate () block within it.

Describe() works similar to a suite in this scenario.

18) Tell us about a few Cypress commands

• cy.visit(): This function is used to browse a certain website.
   
• cy.log(): Cypress console logs are shown during execution using cy.log.
   
• cy.get(): In Cypress, cy. get is used to retrieve DOM elements. Once we have DOM elements, we can execute actions on them, such as clicking, typing, and so on.
   
• cy.URL(): cy.URL() returns the current URL of the currently active page.

19) Which commands are used for interacting with DOM elements?

• .dblclick(): is used to perform a double click on an element.
   
• .type(): This function is used to type on elements or text boxes.
   
• .check(): is used to check checkboxes or radio buttons (s).
   
• .select(): Within a choose>, choose an option>.
   
• .click(): is used to perform a click on the element.
   
• .rightclick(): is used to perform a right-click on an element.
   
• .clear(): is used to clear the fields or text boxes.
   
• .uncheck(): is used to uncheck checkboxes or radio buttons (s).

20) What selectors will Cypress support?

Cypress, by default, only supports CSS selectors. However, we can use a third-party plugin to support Xpath selectors. 

21) In Cypress, what is an environment variable?

The Environment Variables are variables whose values are established at the operating system level and outside of the context of the application or framework.

22) What are Preserve cookies in Cypress?

Cypress clears the cookies after each test by default. To avoid removing cookies, utilize the preserve cookies feature in Cypress.

23) How can you get the first and last child of the selected element?

.first() and.last() are used to obtain the element's first and last child.

24) What exactly are custom commands in Cypress?

Cypress comes with a default set of commands such as cy.visit, cy.relaod, and so on. We can also write our own custom commands in Cypress.

For example, I may write instructions like cy.login() that will prompt the user for their username and password before clicking the submit button.

We may implement the custom command using the code below.

Cypress.Commands.add("login", (username, password) => {
  //adding a new command named login
  cy.get("#username").type(username);
  cy.get("#password").type(password);
  cy.get("#login").click();
});

25) In Cypress, how do you type Keypress?

Keypressing may be done in Cypress using the.type() command. If we need to utilize keys like CTRL, SHIFT, ALT, and so on, we must define them in brackets as seen below.

cy.get(‘login’).type('{shift}{alt}hello'));

26) How to get the title of the page?

cy.title() : cy.title() can be used to get the title of the currently active window

Example:-

cy.title().should('eq','Instagram Login or Signup')

27) How can you get the value from the Cypress Configuration file?

Using Cypress.config(), we can read the cypress.config values.

28) How can you make advantage of the sleep in Cypress?

cy.wait(): This function is used to wait for a specified length of time.

Example:-

cy.wait(1000)

29) In Cypress, how do you get to the shadow DOM?

In Cypress, we may access the aforesaid shadow dom using the code below.

cy.get('.shadow-host').shadow().find('.my-button').click()

30) What exactly is Shadow DOM?

Shadow DOM allows concealed DOM trees to be added to ordinary DOM tree components — this shadow DOM tree begins with a shadow root.
