Test run successfully but if ran again and again then fails in between

[pmahit05]

My Test failing in between. It failing to find element but some times it runs without error.

I tried to perform same on google and found same issue.

describe('My First Test', () => {
 before(() => {
  cy.visit('https://www.google.com/');
 })

it('Search Validation', () => {
 cy.get('input[name="q"]').type('cypress');
 cy.get('form[name="f"]').submit();
 cy.get('a[href="https://docs.cypress.io/guides/overview/why-cypress.html"]').should('be.visible');
 cy.get('input[name="q"]').clear().type('Angular');
})
}) 

Above test fails in between saying form[name="f"] not found.
Any idea why this inconsistent behavior

Cypress version 5.6.0

Could be due to many reasons. Some backend calls that's not taken in to account etc..

The server requests don't always complete within the 5 seconds that Cypress is looking for the form to render.

So either assert on the server requests completely or give more time than 5 secs to find the form element, cy.get('form[name="f"]', { timeout: 30000 }).submit();

Passing
