How can you assert that the URL does NOT contain the substring '/error' in Cypress?
AAll of the above
Bcy.url().should('not.contain', '/error')
Ccy.url().should('not.match', /\/error/)
Dcy.url().should('not.include', '/error')
Step-by-Step Solution
Solution:

  1. Step 1: Understand negation assertions

    Cypress supports negation by prefixing assertions with 'not.'.

  2. Step 2: Check each option validity

    cy.url().should('not.include', '/error') uses 'not.include', valid to check substring absence. cy.url().should('not.contain', '/error') uses 'not.contain', also valid synonym. cy.url().should('not.match', /\/error/) uses 'not.match' with regex, valid to check pattern absence.

  3. Final Answer:

    All of the above -> Option A

  4. Quick Check:

    Negation works with 'not.' prefix on assertions [OK]
Quick Trick: Prefix assertions with 'not.' to check absence [OK]
Common Mistakes:
  • Using '!' inside assertion string
  • Confusing 'not.include' and 'not.contain'
  • Not using regex correctly with 'not.match'
