Now days develoepr has to write test cases for their component code and for test their own functionality.

there are many tools in market like
Chai Moka Jasmine Karma Jest

but Cypress is single tool which is running on top of these above tools. becuase internally cypress use these mentioned tools including Jquery.

Cypress allow you to test your application e2e in browser with very smooth flow.

but sometime while working with cypress we need to get a element and match it's value with another element dynamically so how we can achive that

here I am going to show you how we can take innerText of any DOM element in cypress

cy.get(['YOUR_DOM_ELEMENT']).then(elm => {
  cy.get(['YOUR_DOM_ELEMENT']).should('has.text', elm[0].innerText)
});

I have a question regarding JavaScript.

is this good practice to add our own method in prototype class

like I have added my own custom method in String prototype class like this

String.prototype.mirror = function () {
  let str = this.toString() ;
 return str.split('').reverse().join('')
}

and now i am using my own method with any string value like

"hello".mirror()
"olleh"
