Cypress - Assertions

Consider the code:

const list = ['apple', 'banana', 'cherry'];
expect(list).to.have.length(4);

What will happen when this assertion runs?

ATest passes because list length is 4

BTest passes because length is ignored

CSyntax error due to wrong method

DTest fails because list length is 3

Step-by-Step Solution

Solution:

Step 1: Check the actual length of the list
The list has 3 items, so its length is 3.
Step 2: Compare with expected length in assertion
The assertion expects length 4, which does not match actual length.
Final Answer:
Test fails because list length is 3 -> Option D
Quick Check:
Length mismatch = test fails [OK]

Quick Trick: Check actual length before asserting with to.have.length() [OK]

Common Mistakes:

Assuming length is 4 without counting
Confusing syntax with error
Ignoring assertion failure on mismatch
