# Input value
You can use the have.prop assertion to grab the text value and yield it to the next assertion.
<input id="user-ssn" value="123-45-6789" />
// it looks best if we know the exact value to check
cy.get('#user-ssn').should('have.value', '123-45-6789')
If we don't know the exact value to expect, we can grab the value property and check if it follows a regular expression.
cy.get('#user-ssn')
// you can invoke jQuery "val" method
// or use the "have.prop" assertion
.should('have.prop', 'value')
// yields the string value
.should('match', /^\d\d\d-\d\d-\d\d\d\d$/)
// alternate regular expression
.and('match', /^\d{3}-\d{2}-\d{4}$/)
