In Cypress how to count a selection of items and get the length?

Question

I\'m starting to learn Cypress. I have a 4 row table (with a class of datatable). I can verify the number of rows this way:

cy.get(\'.datatable\').find(\'tr\         


        

Answer 1

Found a solution, This works to check a count of items:

cy.get('.datatable').find('tr').should('have.length', 4)

This does not work with the Cypress.$() method of notation.
