Number Of Children
<div id="parent">
<div>One</div>
<div>Two <strong>*</strong></div>
<div>Three</div>
<div>Four</div>
</div>
Let's confirm the number of immediate children of the parent element.
// using cy.children query command
cy.get('#parent').children().should('have.length', 4)
// using DOM property "childElementCount"
cy.get('#parent').should('have.prop', 'childElementCount', 4)
