💡 Hint

Common Mistakes

Using seconds instead of milliseconds.

Setting timeout too low causing test failures.

The command timeout is set in milliseconds. 10000 means 10 seconds.

2fill in blank

medium

Complete the code to set the assertion timeout to 5 seconds.

Cypress

cy.get('input').should('be.visible', { timeout: [1] })

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

💡 Hint

Common Mistakes

Confusing command timeout with assertion timeout.

Using too short timeout causing flaky tests.

The assertion timeout controls how long Cypress waits for the assertion to pass. 5000 means 5 seconds.

3fill in blank

hard

Fix the error in the code to correctly set command timeout to 8 seconds.

Cypress

cy.get('div', { timeout: [1] })

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

💡 Hint

Common Mistakes

Using seconds instead of milliseconds.

Passing timeout as a string.

Timeout must be a number in milliseconds. 8000 means 8 seconds.

4fill in blank

hard

Fill both blanks to set command timeout to 7 seconds and assertion timeout to 3 seconds.

Cypress

cy.get('span', { timeout: [1] }).should('exist', { timeout: [2] })

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

💡 Hint

Common Mistakes

Mixing up command and assertion timeouts.

Using the same timeout for both.

The command timeout is 7000 ms (7 seconds) and the assertion timeout is 3000 ms (3 seconds).

5fill in blank

hard

Fill all three blanks to set command timeout to 6 seconds, assertion timeout to 4 seconds, and check existence.

Cypress

cy.get('section', { timeout: [1] }).should('be.visible', { timeout: [2] }).and('[3]')

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

💡 Hint

Common Mistakes

Using 'be.enabled' instead of 'exist' for presence check.

Confusing assertion timeout with command timeout.

Command timeout is 6000 ms (6 seconds), assertion timeout is 4000 ms (4 seconds), and the chained assertion checks that the element exists.

Practice

1. What is the main difference between command timeout and assertion timeout in Cypress?

easy

A. Command timeout is for API calls; assertion timeout is for UI rendering.

B. Command timeout waits for page load; assertion timeout waits for network requests.

C. Command timeout waits for actions like finding elements; assertion timeout waits for checks like visibility.

D. Command timeout waits for assertions; assertion timeout waits for commands.

Solution

1. Step 1: Understand command timeout purpose

   Command timeout is the time Cypress waits to find or interact with elements before failing.

2. Step 2: Understand assertion timeout purpose

   Assertion timeout is the time Cypress waits for conditions like visibility or text to become true in assertions.

3. Final Answer:

   Command timeout waits for actions like finding elements; assertion timeout waits for checks like visibility. -> Option C

4. Quick Check:

   Command timeout vs assertion timeout = Command timeout waits for actions like finding elements; assertion timeout waits for checks like visibility. [OK]

Hint: Command = action wait, Assertion = check wait [OK]

Common Mistakes:

• Confusing command timeout with page load timeout
• Thinking assertion timeout waits for commands
• Mixing up API calls with UI element waits

2. Which of the following is the correct way to set a command timeout of 10 seconds in Cypress?

easy

A. cy.get('button', { timeout: 10000 })

B. cy.get('button').timeout(10000)

C. cy.get('button').setTimeout(10000)

D. cy.get('button').waitTimeout(10000)

Solution

1. Step 1: Recall Cypress command timeout syntax

   Timeout for commands like cy.get() is set by passing an options object with timeout in milliseconds.

2. Step 2: Check each option for correct syntax

   Only cy.get('button', { timeout: 10000 }) uses the correct syntax. The others use invalid methods.

3. Final Answer:

   cy.get('button', { timeout: 10000 }) -> Option A

4. Quick Check:

   Command timeout syntax = cy.get('button', { timeout: 10000 }) [OK]

Hint: Timeout is an option object in commands [OK]

Common Mistakes:

• Using non-existent methods like .timeout()
• Passing timeout as a separate method
• Confusing assertion timeout syntax with command timeout

3. Consider this Cypress code snippet:

cy.get('#submit', { timeout: 5000 }).click();
cy.get('#message').should('be.visible', { timeout: 10000 });

What happens if the #submit button appears after 6 seconds and the #message appears after 8 seconds?

medium

A. Test fails at clicking #submit but passes the visibility check for #message.

B. Test passes both clicking #submit and visibility check for #message.

C. Test fails both clicking #submit and visibility check for #message.

D. Test passes clicking #submit but fails visibility check for #message.

Solution

1. Step 1: Analyze command timeout for #submit

   The command timeout is 5000 ms (5 seconds). The button appears after 6 seconds, which is too late, so the click command fails.

2. Step 2: Analyze assertion timeout for #message

   The assertion timeout is 10000 ms (10 seconds). The message appears after 8 seconds, which is within timeout, so the assertion passes.

3. Final Answer:

   Test fails at clicking #submit but passes the visibility check for #message. -> Option A

4. Quick Check:

   Command timeout too short, assertion timeout sufficient = Test fails at clicking #submit but passes the visibility check for #message. [OK]

Hint: Command timeout limits action wait; assertion timeout limits check wait [OK]

Common Mistakes:

• Assuming both timeouts behave the same
• Ignoring timeout values in options
• Thinking assertion timeout affects commands

4. You wrote this Cypress test:

cy.get('.loading', { timeout: 3000 }).should('not.exist');

But the test fails because the element disappears after 5 seconds. What is the best fix?

medium

A. Increase the command timeout to more than 5000 ms.

B. Change should('not.exist') to should('be.visible').

C. Add a cy.wait(5000) before the assertion.

D. Increase the assertion timeout to more than 5000 ms.

Solution

1. Step 1: Identify what is being waited on

   The test waits for the element to disappear, which is an assertion (should('not.exist')).

2. Step 2: Adjust the correct timeout

   The command timeout controls finding the element, but the assertion timeout controls waiting for the condition. Since the element disappears after 5 seconds, increase assertion timeout beyond 5000 ms.

3. Final Answer:

   Increase the assertion timeout to more than 5000 ms. -> Option D

4. Quick Check:

   Assertion timeout controls condition wait = Increase the assertion timeout to more than 5000 ms. [OK]

Hint: Wait for condition? Increase assertion timeout [OK]

Common Mistakes:

• Increasing command timeout instead of assertion timeout
• Using fixed wait instead of timeout adjustment
• Changing assertion logic incorrectly

5. You want to test a slow-loading modal that appears after clicking a button. The button may take up to 4 seconds to appear, and the modal may take up to 7 seconds to become visible. Which is the best way to set timeouts in Cypress?

hard

A. Use cy.get('button').click({ timeout: 7000 }) and cy.get('.modal').should('be.visible', { timeout: 4000 }).

B. Use cy.get('button', { timeout: 5000 }).click() and cy.get('.modal').should('be.visible', { timeout: 8000 }).

C. Use cy.get('button', { timeout: 3000 }).click() and cy.get('.modal').should('be.visible', { timeout: 3000 }).

D. Use cy.get('button').click() and cy.get('.modal').should('be.visible') with no timeouts set.

Solution

1. Step 1: Set command timeout for button appearance

   The button may appear after up to 4 seconds, so set command timeout slightly higher (5000 ms) to allow finding it.

2. Step 2: Set assertion timeout for modal visibility

   The modal may take up to 7 seconds to appear, so set assertion timeout higher (8000 ms) to wait for visibility.

3. Final Answer:

   Use cy.get('button', { timeout: 5000 }).click() and cy.get('.modal').should('be.visible', { timeout: 8000 }). -> Option B

4. Quick Check:

   Command timeout for action, assertion timeout for condition = Use cy.get('button', { timeout: 5000 }).click() and cy.get('.modal').should('be.visible', { timeout: 8000 }). [OK]

Hint: Set command timeout for element, assertion timeout for checks [OK]

Common Mistakes:

• Swapping timeout values between command and assertion
• Setting timeouts too low causing flaky tests
• Not setting timeouts causing premature failures
