Cookie management in Cypress - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to visit a page and clear all cookies.

Cypress

cy.visit('https://example.com')
cy.[1]()

Drag options to blanks, or click blank then click option'

AclearCookies

BclearCookies()

CclearCookiesAll

DclearCookiesAll()

Attempts:

💡 Hint

Common Mistakes

Forgetting parentheses after the command name.

Using a non-existent command like clearCookiesAll.

The correct Cypress command to clear all cookies is cy.clearCookies(). It clears all cookies for the current domain.

2fill in blank

medium

Complete the code to set a cookie named 'session_id' with value 'abc123'.

Cypress

cy.setCookie('[1]', 'abc123')

Drag options to blanks, or click blank then click option'

Atoken

Buser_id

Cauth

Dsession_id

Attempts:

💡 Hint

Common Mistakes

Using a wrong cookie name like 'token' or 'auth'.

The cookie name to set is session_id as required.

3fill in blank

hard

Fix the error in the code to get a cookie named 'user_token'.

Cypress

cy.getCookie([1]).should('exist')

Drag options to blanks, or click blank then click option'

Auser_token

B'user_token'

C"user_token"

DuserToken

Attempts:

💡 Hint

Common Mistakes

Passing the cookie name without quotes causing a reference error.

Using a wrong cookie name like 'userToken'.

The cookie name must be a string literal, so it needs quotes like 'user_token'.

4fill in blank

hard

Fill both blanks to check that the cookie 'auth' has value 'true'.

Cypress

cy.getCookie('[1]').its('value').should('[2]', 'true')

Drag options to blanks, or click blank then click option'

Aauth

Bhave.property

Ceq

Dexist

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'exist' instead of 'eq' to check the cookie value.

Using 'have.property' which is incorrect here.

The cookie name is auth. To check its value, use .its('value').should('eq', 'true').

5fill in blank

hard

Fill all three blanks to clear a cookie named 'session', then verify it no longer exists.

Cypress

cy.clearCookie('[1]').then(() => {
  cy.getCookie('[2]').should('[3]')
})

Drag options to blanks, or click blank then click option'

Asession

Bsession_id

Cnot.exist

Dexist

Attempts:

3 left

💡 Hint

Common Mistakes

Using different cookie names in clear and getCookie calls.

Using 'exist' instead of 'not.exist' to check absence.

We clear the cookie named session. Then we check that the same cookie no longer exists using should('not.exist').

Practice

1. What is the main purpose of managing cookies in Cypress tests?

easy

A. To speed up the browser rendering process

B. To change the website's HTML structure

C. To store and verify small pieces of information like user sessions

D. To create new browser tabs automatically

Solution

1. Step 1: Understand what cookies do

   Cookies store small data like user sessions or preferences to remember users.

2. Step 2: Relate to Cypress testing

   Cypress manages cookies to test if the site remembers users or settings correctly.

3. Final Answer:

   To store and verify small pieces of information like user sessions -> Option C

4. Quick Check:

   Cookies store info = A [OK]

Hint: Cookies store user info; Cypress tests that info [OK]

Common Mistakes:

• Thinking cookies change page layout
• Confusing cookies with browser tabs
• Assuming cookies speed up rendering

2. Which Cypress command correctly sets a cookie named session_id with value abc123?

easy

A. cy.setCookie('session_id', 'abc123')

B. cy.cookieSet('session_id', 'abc123')

C. cy.set('session_id', 'abc123')

D. cy.createCookie('session_id', 'abc123')

Solution

1. Step 1: Recall Cypress cookie setting syntax

   The correct command to set a cookie is cy.setCookie(name, value).

2. Step 2: Match the command with options

   Only cy.setCookie('session_id', 'abc123') uses cy.setCookie with correct parameters.

3. Final Answer:

   cy.setCookie('session_id', 'abc123') -> Option A

4. Quick Check:

   Use cy.setCookie() to set cookies [OK]

Hint: Use cy.setCookie(name, value) to set cookies [OK]

Common Mistakes:

• Using wrong command names like cookieSet or createCookie
• Confusing cy.set with cy.setCookie
• Missing quotes around cookie name or value

3. What will be the output of this Cypress code snippet?

cy.setCookie('token', 'xyz789')
cy.getCookie('token').should('have.property', 'value', 'xyz789')

medium

A. Test passes because cookie 'token' has value 'xyz789'

B. Test fails because cookie 'token' is not set

C. Syntax error due to wrong command usage

D. Test passes but cookie value is empty string

Solution

1. Step 1: Analyze cookie setting

   The code sets a cookie named 'token' with value 'xyz789' using cy.setCookie.

2. Step 2: Analyze assertion

   The code gets the cookie 'token' and asserts its value property equals 'xyz789'. This matches the set value.

3. Final Answer:

   Test passes because cookie 'token' has value 'xyz789' -> Option A

4. Quick Check:

   Set cookie then assert value = Pass [OK]

Hint: Set cookie then assert value matches to pass test [OK]

Common Mistakes:

• Assuming getCookie returns undefined if setCookie was called
• Confusing property name in assertion
• Thinking syntax is incorrect

4. Identify the error in this Cypress code that tries to clear all cookies:

cy.clearCookie()

medium

A. clearCookie clears all cookies without arguments, so no error

B. clearCookie requires a cookie name argument to clear a specific cookie

C. clearCookie is not a valid Cypress command

D. clearCookie must be called with an array of cookie names

Solution

1. Step 1: Understand clearCookie usage

   cy.clearCookie() requires a cookie name string to clear one cookie.

2. Step 2: How to clear all cookies

   To clear all cookies, use cy.clearCookies() (note plural) without arguments.

3. Final Answer:

   clearCookie requires a cookie name argument to clear a specific cookie -> Option B

4. Quick Check:

   clearCookie needs name; clearCookies clears all [OK]

Hint: Use clearCookies() to clear all, clearCookie(name) for one [OK]

Common Mistakes:

• Calling clearCookie() without name to clear all
• Confusing clearCookie with clearCookies
• Assuming clearCookie accepts multiple names

5. You want to test that a user stays logged in after a page reload by preserving the auth_token cookie. Which Cypress approach correctly achieves this?

hard

A. Use cy.reload(preserveCookies: true) to keep cookies

B. Use cy.preserveCookie('auth_token') before reload

C. Use cy.clearCookies() before reload to reset cookies

D. Use cy.getCookie('auth_token').then(cookie => { cy.setCookie(cookie.name, cookie.value) }) after reload

Solution

1. Step 1: Understand cookie preservation

   Cypress clears cookies on reload by default, so to keep a cookie, you must reset it after reload.

2. Step 2: Analyze options

   Use cy.getCookie('auth_token').then(cookie => { cy.setCookie(cookie.name, cookie.value) }) after reload manually gets and sets the cookie again after reload, which preserves it correctly. Use cy.preserveCookie('auth_token') before reload is invalid syntax. Use cy.clearCookies() before reload to reset cookies clears cookies, which removes the token. Use cy.reload({ preserveCookies: true }) to keep cookies is not a valid reload option in Cypress.

3. Final Answer:

   Use cy.getCookie('auth_token').then(cookie => { cy.setCookie(cookie.name, cookie.value) }) after reload -> Option D

4. Quick Check:

   Manually reset cookie after reload to preserve [OK]

Hint: Manually reset cookie after reload to keep it [OK]

Common Mistakes:

• Assuming reload keeps cookies automatically
• Using non-existent preserveCookie command
• Clearing cookies before reload by mistake
