Input valueAsNumber example

If the input element has type "number" you can check its property valueAsNumber to avoid converting the string value into a number.

<input type="number" id="age" value="22" />
<input type="number" id="glass" value="0.5" />
  .should('have.value', '22')
  .and('have.prop', 'valueAsNumber', 22)

You can yield the property value to run more assertions

  // yields the value of the prop
  .should('have.prop', 'valueAsNumber')
  // if we only know the lower and upper limits
  .should('be.within', 15, 25)

It works with floating point values too.

  .should('have.value', '0.5')
  .and('have.prop', 'valueAsNumber', 0.5)
// if we know the value approximately
  .should('have.prop', 'valueAsNumber')
  .should('be.closeTo', 0.49, 0.1)
