Difference between JQuery vs Cypress

jQuery Cypress Test Automation Software Testing

Cypress can work on JQuery objects and call its methods. Thus Cypress can act upon both Cypress and non- Cypress commands. Cypress is asynchronous in nature. It is handled by resolving promises for every Cypress command. This whole process is taken care of by Cypress internally and wrapped and hidden from the end user.

However while dealing with JQuery methods, the promise cannot be resolved internally by Cypress and we need to manually resolve them with the help of the then() method in the code.

Let us take the example of text() method which is a non-Cypress command and is based on JQuery.

Example

Code Implementation to handle promise for JQuery.

// test suite
describe('Tutorialspoint Test', function () {
   // test case
   it('Test Case1', function (){
      // test step to launch a URL
      cy.visit("https://www.tutorialspoint.com/index.htm");
      // enter test in the edit box
      // assertion to validate the number of child elements
      cy.get('#gs_50d > tbody > tr > td'). should('have.length',2);
      // locate element with get and find method
      cy.get('#gs_50d > tbody > tr > td'). find('input')
      //enter test in the edit box
      .type('Cypress');
      //iterate the list items with each command
      cy.get('.mui-tabs__bar.mui-tabs__bar_1.mui-tabs__bar--justified')
      .find('li').each(($el, index, $list) => {
         // extract text with text() method
         const txt = $el.find('a').text();
         if ( txt.includes('Deve')){
            $el.click();
         }
      })
      //handling promise with then() for non in built Cypress function
      cy.get('mui-container > h4').then(function(heading){
         cy.log(heading.text());
      })
   });
});

On running the above block of code, Cypress Test runner gives the below output. Please note the log printed with text() method handled with then().
