cy.first(), cy.last(), cy.eq() in Cypress - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does cy.first() do in Cypress?

cy.first() selects the first element from a set of matched elements in the DOM.

Think of it like picking the first apple from a basket.

beginner

How does cy.last() differ from cy.first()?

cy.last() selects the last element from a set of matched elements, while cy.first() selects the first.

Imagine picking the last cookie from a jar instead of the first.

beginner

Explain the purpose of cy.eq(index).

cy.eq(index) selects the element at the given zero-based index from matched elements.

It's like choosing the 3rd book on a shelf by counting from the start.

beginner

What is the index base used by cy.eq()?

cy.eq() uses zero-based indexing, meaning the first element is at index 0.

So, cy.eq(0) is the same as cy.first().

beginner

Why is it useful to use cy.first(), cy.last(), or cy.eq() in tests?

They help you pick a specific element from many, making tests precise and reliable.

Like choosing the exact item you want to check in a list.

What does cy.first() select?

A An element by index

B The last element from matched elements

C The first element from matched elements

D All elements

cy.first() picks the first element only.

Which command selects the last element in a set?

A cy.eq(0)

B cy.last()

C cy.eq(-1)

D cy.first()

cy.last() selects the last element.

What index does cy.eq(2) select?

A Third element

B Second element

C First element

D Last element

Index 2 means the third element (zero-based counting).

If you want the second element, which command is correct?

A cy.eq(2)

B cy.last()

C cy.first()

D cy.eq(1)

Index 1 is the second element in zero-based indexing.

Which command is equivalent to cy.eq(0)?

A cy.first()

B cy.last()

C cy.eq(1)

D cy.eq(-1)

cy.first() selects the first element, same as cy.eq(0).

Describe how cy.first(), cy.last(), and cy.eq() help in selecting elements during testing.

Think about picking items from a list or basket.

Explain zero-based indexing in the context of cy.eq().

Remember how arrays count in programming.
