Cypress - Component Testing

What will happen if you run this Cypress test?

const onChange = cy.spy();
cy.mount();
cy.get('input').type('abc');
expect(onChange).to.have.callCount(3);

ATest passes because onChange is called 3 times for each character

BTest fails because callCount is not a valid assertion

CTest fails because onChange is called once only

DTest passes but callCount should be calledWith instead

Step-by-Step Solution

Solution:

Step 1: Understand typing triggers onChange
Typing 'abc' triggers onChange event 3 times, once per character.
Step 2: Verify assertion callCount usage
calledWith is for arguments; callCount checks number of calls, which is valid here.
Final Answer:
Test passes because onChange is called 3 times for each character -> Option A
Quick Check:
Typing triggers onChange calls = callCount 3 [OK]

Quick Trick: Typing triggers multiple onChange calls, count them correctly [OK]
