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

One option is to use "have.length" ...

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

...another option is to use should

cy.get('.datatable tr').should(($tr) => {
    expect($tr).to.have.length(4)
})

...or then (synchronous queries)

cy.get('.datatable').then(($table) => {
  // synchronously query to find length of elements
  expect($table.find('td').length).to.equal(4)
})
