cy.exist function to allow existence checking conditional testing

cy.exist conditional testing.js

// Anti-pattern conditional testing with Cypress
// Uses jQuery functionality to determine existence

// Add to your support folder
Cypress.Commands.add("exist", (selector) => {
  cy.get('body').should('exist').then(($body) => {
    return new Cypress.Promise((resolve, reject) => {
      if ($body.find(selector).length > 0) {
        console.log("cy.exist() - Matching element found in DOM!");
        resolve(true);
      } else {
        console.log("cy.exist() - Element did not exist!");
        resolve(false);
      }
    })
  })
})


// Add to your step definitions
cy.exist("#button1").then((exists) => {
  if (exists) {
    //element does exist
  } else {
    //element does not exist
  }
})
