Using Regular expressions inside the cy.contains()

Cypress allows the use of regular expressions inside contains() function.
As seen in the below example, you can search for the element containing text that starts with b and has one or more word characters (numbers, alphabets, and _)

cy.contains(/^b\w+/)

To ignore the Case Sensitivity while using regular expressions inside contains() function, use { matchCase: false }

cy.get(‘div’).contains(‘capital sentence’, { matchCase: false })
