count number of children returned and push the children attribute into array using Cypress

I am trying to count the number of children returned when doing

cy.xpath(NODE_PREVIEW_PANEL).children('data-testid')

So that I can use the count to pass all the values into an array sequentially avoiding the async of .each() function.

How can I get the count of children here?

(or you can suggest a totally different solution)

Solution

  • One way I use successfully is to use reference variable

    let variablesToValidate = {
    numberOfChildren: 0,
    attributes: []
}
cy.xpath(NODE_PREVIEW_PANEL)
    .children('data-testid')
    .each(($element, index, $array) =>{
        cy.wrap($element)
            .should('have.attr', 'attributeName')
            .then(atrributeValue => variablesToValidate.attributes.push(atrributeValue))
    })
    .then($array => variablesToValidate.numberOfChildren = $array.length)
