Checking length of element in beforeEach on Cypress
Solution 1:
Cypress commands are asynchronous. So when the test executes cy.visit("/") it does not mean that the next line will be executed after the page gets really loaded.
You can fix this as follows:
beforeEach(() => {
cy.visit("/").then(() => {
let count = Cypress.$('#emails').length
cy.log(count)
if(count == 0) {
createNewEmail()
}
})
}
