Practice - 5 Tasks

1fill in blank

Complete the code to get the previous sibling element using Cypress.

Cypress

💡 Hint

Common Mistakes

Using cy.next() instead of cy.prev() to get the previous sibling.

Using cy.parent() which gets the parent element, not the sibling.

The cy.prev() command gets the previous sibling of the selected element.

2fill in blank

medium

Complete the code to get the next sibling element using Cypress.

Cypress

cy.get('.button').[1]()

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

Bsiblings

Cnext

Dchildren

💡 Hint

Common Mistakes

Using cy.prev() instead of cy.next() to get the next sibling.

Using cy.children() which gets child elements, not siblings.

The cy.next() command gets the next sibling of the selected element.

3fill in blank

hard

Fix the error in the code to correctly get the previous sibling element.

Cypress

cy.get('.active').[1]

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

Aprev

Bprev()

Cnext()

Dsiblings()

💡 Hint

Common Mistakes

Forgetting to add parentheses after the command name.

Using cy.next() instead of cy.prev() when wanting the previous sibling.

The cy.prev() command must be called as a function with parentheses to work correctly.

4fill in blank

hard

Fill both blanks to get the next sibling and then its previous sibling.

Cypress

cy.get('.start').[1]().[2]()

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

Anext

Bprev

Csiblings

Dparent

Attempts:

3 left

💡 Hint

Common Mistakes

Reversing the order of commands.

Using cy.siblings() which gets all siblings, not just next or previous.

First, cy.next() gets the next sibling, then cy.prev() gets its previous sibling (which is the original element).

5fill in blank

hard

Fill all three blanks to get the previous sibling, then its next sibling, and finally its parent element.

Cypress

cy.get('.item').[1]().[2]().[3]()

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

Aprev

Bnext

Cparent

Dchildren

Attempts:

3 left

💡 Hint

Common Mistakes

Using cy.children() instead of cy.parent() at the end.

Mixing up the order of prev and next commands.

This chain first gets the previous sibling, then its next sibling (which returns to the original element), and finally the parent element.

Practice

1. What does cy.prev() do in Cypress testing?

easy

A. Selects the element immediately after the current element

B. Selects all sibling elements of the current element

C. Selects the element immediately before the current element

D. Selects the parent element of the current element

Solution

1. Step 1: Understand the purpose of cy.prev()

   cy.prev() is used to get the element immediately before the current element in the DOM.

2. Step 2: Compare with other options

   cy.next() gets the element after, siblings means all at the same level, and parent is the container element. So only cy.prev() matches Selects the element immediately before the current element.

3. Final Answer:

   Selects the element immediately before the current element -> Option C

4. Quick Check:

   cy.prev() = previous element [OK]

Hint: Prev means previous element before current [OK]

Common Mistakes:

• Confusing cy.prev() with cy.next()
• Thinking it selects parent or all siblings
• Assuming it selects elements after current

2. Which of the following is the correct syntax to get the next sibling element of a button with id submitBtn using Cypress?

easy

A. cy.get('#submitBtn').prev()

B. cy.get('#submitBtn').next()

C. cy.get('#submitBtn').parent()

D. cy.get('#submitBtn').children()

Solution

1. Step 1: Identify the method to get next sibling

   To get the next sibling element, Cypress uses cy.next().

2. Step 2: Match syntax with the element selector

   cy.get('#submitBtn').next() correctly selects the button and then its next sibling.

3. Final Answer:

   cy.get('#submitBtn').next() -> Option B

4. Quick Check:

   next() gets next sibling [OK]

Hint: Use .next() after .get() to get next sibling [OK]

Common Mistakes:

• Using .prev() instead of .next()
• Using .parent() which gets the container
• Using .children() which gets child elements

3. Given the HTML structure:

<ul>
  <li>Item 1</li>
  <li id="selected">Item 2</li>
  <li>Item 3</li>
</ul>

What text will the following Cypress command get?

cy.get('#selected').prev().invoke('text')

medium

A. Error: No previous element

B. "Item 3"

C. "Item 2"

D. "Item 1"

Solution

1. Step 1: Identify the current element and its previous sibling

   The element with id "selected" is the second <li> with text "Item 2". Its previous sibling is the first <li> with text "Item 1".

2. Step 2: Understand what invoke('text') does

   This command gets the text content of the selected element, so it will return "Item 1".

3. Final Answer:

   "Item 1" -> Option D

4. Quick Check:

   prev() gets previous sibling text [OK]

Hint: prev() gets previous sibling's text [OK]

Common Mistakes:

• Confusing prev() with next()
• Expecting text of current element
• Assuming error if previous exists

4. You wrote this Cypress code:

cy.get('.active').next().click()

But the test fails with an error saying Cannot read property 'click' of undefined. What is the most likely cause?

medium

A. There is no next sibling element after the element with class 'active'

B. The selector '.active' is incorrect

C. You should use prev() instead of next()

D. The click() method is not valid in Cypress

Solution

1. Step 1: Analyze the error message

   The error says Cannot read property 'click' of undefined, meaning next() returned no element.

2. Step 2: Understand what causes next() to return undefined

   If the current element has no next sibling, next() returns nothing, so calling click() fails.

3. Final Answer:

   There is no next sibling element after the element with class 'active' -> Option A

4. Quick Check:

   next() returns undefined if no next sibling [OK]

Hint: Check if next sibling exists before clicking [OK]

Common Mistakes:

• Assuming selector is wrong without checking DOM
• Using prev() instead of next() without reason
• Thinking click() is invalid in Cypress

5. You want to verify that a list item with class selected has a previous sibling with text "Home" and a next sibling with text "Contact". Which Cypress code correctly checks this?

hard

A. cy.get('.selected').prev().should('have.text', 'Home'); cy.get('.selected').next().should('have.text', 'Contact')

B. cy.get('.selected').prev().should('have.text', 'Home').next().should('have.text', 'Contact')

C. cy.get('.selected').prev().should('have.text', 'Contact').next().next().should('have.text', 'Home')

D. cy.get('.selected').prev().next().should('have.text', 'Contact')

Solution

1. Step 1: Understand chaining of prev() and next()

   Using prev() then next() on the same chain moves from previous element back to the selected element, not to the next sibling.

2. Step 2: Separate commands for previous and next siblings

   To check previous and next siblings independently, use separate cy.get('.selected') calls with prev() and next().

3. Final Answer:

   cy.get('.selected').prev().should('have.text', 'Home'); cy.get('.selected').next().should('have.text', 'Contact') -> Option A

4. Quick Check:

   Use separate calls for prev() and next() [OK]

Hint: Use separate cy.get() for prev() and next() checks [OK]

Common Mistakes:

• Chaining prev() and next() incorrectly
• Using next().next() instead of next()
• Assuming prev().next() gets next sibling
