Cypress.io: How To Send A Trigger Out Of Cy.then Or Cy.each Function?

Question

I try to verify weather if there have store keyword I want between the elements of pages. For example: store keyword = 'apple' the part structure of a page:

Solution 1:

What you're after is probably best solved by a recursive command/helper that crawls the pages until a store is found or until no other page/stores are left.

Below, the findStore is a function that calls _walkStores which is recursive. It crawls current page, and tries to load next page if nothing is found.
