Expanding on @Prophet's answer:

I would test the placeholder and the value of the input, in that order.

cy.get('your textarea selector')
.should('have.attr','placeholder','Enter a comment.')
.type('stackoverflow')
.should('have.value','stackoverflow')

Edit: Checking if the textarea is empty before typing (more robust test). Another option could be doing a .clear before the .type

cy.get('your textarea selector')
.should('have.attr','placeholder','Enter a comment.')
.should('have.value','')
.type('stackoverflow')
.should('have.value','stackoverflow')

You can get the value attribute of that textarea element.
Something like the following:

theValue = textarea.getAttribute('value')
