How to check if element exists using Cypress.io

Question

How to check if element is present or not, so that certain steps can be performed if element is present. Else certain different steps can be performed if element is not present.

I tried something like below but it didn't work:

Cypress.Commands.add('deleteSometheingFunction', () => {   cy.get('body').then($body => {     if ($body.find(selectors.ruleCard).length) {       let count = 0;       cy.get(selectors.ruleCard)         .each(() => count++)         .then(() => {           while (count-- > 0) {             cy.get('body')             // ...             // ...           }         });     }   });   }); 

I am looking for a simple solution, which can be incorporated with simple javascript if else block or then() section of the promise

Something similar to Webdriver protocol's below implementions:

1. driver.findElements(By.yourLocator).size() > 0
2. check for presenece of element in wait

Kindly advise. Thanks

I'll just add that if you decide to do if condition by checking the .length property of cy.find command, you need to respect the asynchronous nature of cypress.

Example: Following condition evaluates as false despite appDrawerOpener button exists

    if (cy.find("button[data-cy=appDrawerOpener]").length > 0)    //evaluates as false 

But this one evaluates as true because $body variable is already resolved as you're in .then() part of the promise:

    cy.get("body").then($body => {         if ($body.find("button[data-cy=appDrawerOpener]").length > 0) {                //evaluates as true         }     }); 

Read more in Cypress documentation on conditional testing

Answer 2

it has been questioned before: Conditional statement in cypress

Thus you can basically try this:

cy.get('header').then(($a) => {          if ($a.text().includes('Account')) {             cy.contains('Account')             .click({force:true})         } else if ($a.text().includes('Sign')) {              cy.contains('Sign In')             .click({force:true})           } else {             cy.get('.navUser-item--account .navUser-action').click({force:true})         }     })
