medium📝 Debug Q6 of 15
Cypress - Assertions
Identify the error in this Cypress code:
cy.get('div').should('have.class', 'container' && 'visible')
AMissing chaining of multiple should() calls
BWrong selector syntax
CIncorrect use of logical AND inside should() argument
DNo error, code is correct
Step-by-Step Solution
Solution:
  1. Step 1: Analyze the argument inside should()

    The expression 'container' && 'visible' evaluates to 'visible' in JavaScript, so only one class is checked.
  2. Step 2: Identify correct way to check multiple classes

    Multiple classes require separate assertions or chaining, not logical operators inside a string argument.
  3. Final Answer:

    Incorrect use of logical AND inside should() argument -> Option C
  4. Quick Check:

    Logical operators inside should() string argument cause errors [OK]
Quick Trick: Do not use logical operators inside should() string arguments [OK]
Common Mistakes:
  • Using && inside should() string argument
  • Expecting multiple classes checked in one string
  • Ignoring chaining for multiple assertions
