Based on the answer about Vuex, I did that, which works:
// after createStore(...)if (window.Cypress) { window.__store__ = store;}// in cypress testscy.window().should('have.property', '__store__');cy.window().its('__store__') .then( store => store.dispatch({ type: 'UPDATE_CURRENT_PROFILE' }) );
Don't forget to cy.visit('anyRoute')
before doing anything with the store, so that React app is started and redux store is already created when you try to access it.
