Cookie management in Cypress - Practice Problems & Coding Challenges

Challenge - 5 Problems

❓ Predict Output

What is the output of this Cypress test snippet?

Consider the following Cypress test code that sets a cookie and then checks its value. What will be the assertion result?

Cypress

cy.setCookie('session_id', 'abc123')
  .getCookie('session_id')
  .should('have.property', 'value', 'abc123')

A Test passes because the cookie value matches 'abc123'.

B Test passes but the cookie value is undefined.

C Test fails because 'should' cannot check cookie properties.

D Test fails because 'getCookie' is not a valid Cypress command.

💡 Hint

Remember that Cypress commands like setCookie and getCookie work asynchronously and can be chained.

The code sets a cookie named 'session_id' with value 'abc123'. Then it retrieves the cookie and asserts that its 'value' property equals 'abc123'. However, 'getCookie' is not a valid Cypress command; the correct command is 'cy.getCookie'.

❓ assertion

intermediate

Which assertion correctly verifies a cookie named 'user' exists in Cypress?

You want to check if a cookie named 'user' exists after login. Which assertion is correct?

A cy.getCookie('user').should('exist')

B cy.getCookie('user').should('have.property', 'name', 'user')

C cy.getCookie('user').should('have.value', 'user')

D cy.getCookie('user').should('contain', 'user')

💡 Hint

Check the properties of the cookie object returned by getCookie.

The cookie object has properties like 'name' and 'value'. To verify the cookie named 'user' exists, check that the 'name' property equals 'user'.

Why does this Cypress test fail to clear cookies?

This test tries to clear cookies but fails. Identify the reason.

Cypress

cy.clearCookies('session_id')
cy.getCookie('session_id').should('not.exist')

A getCookie cannot be chained after clearCookies.

B The cookie name 'session_id' is invalid.

C clearCookies does not accept arguments; it clears all cookies only.

D should('not.exist') is not a valid assertion for cookies.

💡 Hint

Check the Cypress documentation for clearCookies usage.

The clearCookies command clears all cookies and does not accept any arguments. Passing a cookie name causes the command to ignore the argument and not clear specific cookies.

🧠 Conceptual

advanced

What is the best practice for managing cookies in Cypress tests to avoid flaky tests?

Which practice helps ensure cookie-related tests are reliable and isolated?

A Clear all cookies before each test to start fresh.

B Set cookies only once before all tests run.

C Avoid clearing cookies to speed up tests.

D Manually delete cookies using browser DevTools during tests.

💡 Hint

Think about test isolation and repeatability.

Clearing cookies before each test ensures no leftover data affects test results, making tests independent and reliable.

Which Cypress command sequence correctly sets a cookie, reloads the page, and verifies the cookie persists?

Select the correct code snippet that sets a cookie named 'token' with value 'xyz', reloads the page, and asserts the cookie still exists with the correct value.

A

cy.setCookie('token', 'xyz')
cy.reload()
cy.getCookie('token').should('have.property', 'value', 'xyz')

B

cy.setCookie('token', 'xyz')
cy.reload()
cy.getCookie('token').should('equal', 'xyz')

C

cy.setCookie('token', 'xyz')
  .reload()
  .getCookie('token')
  .should('have.property', 'value', 'xyz')

D

cy.setCookie('token', 'xyz')
  .reload()
  .getCookie('token')
  .should('equal', 'xyz')

💡 Hint

Remember Cypress commands are asynchronous and chaining vs separate calls matters.

Option A correctly sets the cookie, reloads the page, then gets the cookie and asserts its 'value' property equals 'xyz'. The commands are properly sequenced without chaining incompatible commands.
