Parent commands 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. What will be the text content of the parentText variable after running?

Cypress

cy.get('ul#list > li.selected').parent().invoke('text').then(parentText => {
  cy.log(parentText);
});

A The text content of the <ul> element containing the selected <li>

B The text content of the selected <li> element only

C An empty string because <ul> has no text

D A JavaScript error because parent() is not a valid Cypress command

💡 Hint

Remember, parent() moves up one level in the DOM tree.

The parent() command selects the immediate parent element of the matched element(s). Here, it selects the ul#list element. Invoking text on it returns all text inside the

, including all
• children.

❓ assertion

Which assertion correctly verifies the parent element's class?

You want to check that the parent of a button with id submitBtn has the class form-group. Which assertion is correct?

Cypress

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

A cy.get('#submitBtn').parent().should('contain', 'form-group')

B cy.get('#submitBtn').parent().should('have.class', 'form-group')

C cy.get('#submitBtn').parent().should('have.text', 'form-group')

D cy.get('#submitBtn').parent().should('have.attr', 'form-group')

💡 Hint

Use the correct assertion to check for a CSS class.

The have.class assertion checks if the element has the specified CSS class. Other options check for text content or attributes, which are incorrect here.

Why does this Cypress test fail to find the parent element?

Given this code, the test fails with Timed out retrying error. Why?

Cypress

cy.get('.child-element').parent('.nonexistent-class').should('exist');

A Because <code>parent()</code> only accepts no arguments; passing a selector causes failure

B Because <code>parent()</code> returns all ancestors, not just immediate parent

C Because <code>should('exist')</code> is invalid syntax

D Because the parent element does not have the class <code>nonexistent-class</code>, so the chain yields no elements

💡 Hint

Check if the parent element matches the selector passed to parent().

The parent() command can take a selector to filter the immediate parent. If the parent does not match, the result is empty, causing the should('exist') assertion to fail.

🧠 Conceptual

advanced

What is the difference between parent() and parents() in Cypress?

Choose the best explanation of how parent() and parents() differ in Cypress DOM traversal.

A <code>parent()</code> and <code>parents()</code> are aliases and behave identically

B <code>parent()</code> selects all ancestors; <code>parents()</code> selects only the immediate parent

C <code>parent()</code> selects the immediate parent; <code>parents()</code> selects all ancestors up to the root

D <code>parent()</code> selects siblings; <code>parents()</code> selects children

💡 Hint

Think about how many levels up each command goes.

parent() moves one level up to the immediate parent. parents() moves up all levels, returning all ancestors up to the document root.

❓ framework

Which Cypress command chain correctly clicks a button's parent element and verifies its visibility?

Given a button with class btn-action, you want to click its parent element and then check if that parent is visible. Which command chain is correct?

A cy.get('.btn-action').parent().should('be.visible').click();

B cy.get('.btn-action').parent().click().should('be.visible');

C cy.get('.btn-action').click().parent().should('be.visible');

D cy.get('.btn-action').parent().click().should('exist');

💡 Hint

Remember Cypress commands are asynchronous and chainable; order matters.

Option A first gets the parent, asserts it is visible, then clicks it. This ensures the parent is visible before clicking. Option A clicks before asserting visibility, which may cause flaky tests. Option A clicks the button, then tries to get parent, which is invalid chaining. Option A asserts existence, not visibility.
