Cypress - Assertions

You want to assert that an array items contains exactly 3 elements and includes the string "book". Which of the following is the correct way to write this using expect()?

Aexpect(items).to.have.length(3).include('book')

Bexpect(items).to.have.length(3).and.include('book')

Cexpect(items).to.have.lengthOf(3).and.to.include('book')

Dexpect(items).to.include('book').and.to.have.length(3)

Step-by-Step Solution

Solution:

Step 1: Check chaining syntax for length and inclusion
Chaining with .and. is correct to combine assertions.
Step 2: Verify method names and order
to.have.length(3) and include('book') are valid; chaining order is flexible but .and. is needed.
Final Answer:
expect(items).to.have.length(3).and.include('book') -> Option B
Quick Check:
Use .and. to chain multiple expect assertions [OK]

Quick Trick: Chain assertions with .and. for multiple checks [OK]

Common Mistakes:

Missing .and. between assertions
Using lengthOf instead of length
Wrong chaining order without .and.
