In Cypress how to count a selection of items and get the length?
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.$()
method of notation.
Reference: https://docs.cypress.io/guides/references/assertions.html#Length
You can also get the length of a selection of items through its property, for example:
cy.get('.datatable').find('tr').its('length').should('eq', 4)
cy.get('.datatable').find('tr').its('length').should('be.gte', 4)
In addition to should('have.length', 4)
I tested with Cypress version 3.1.0 and 3.2.0.
if you want more flexible and have a dynamic result use this.
cy.get('.listings-grid')
.find('.listing')
.then(listing => {
const listingCount = Cypress.$(listing).length;
expect(listing).to.have.length(listingCount);
});
