There seems to be an error with test cases it self. while testing employeeID the name is passed as Use (which is not a 4 chars).

The test is outdate. so if you want to get current date and compare to the input date it will give you error. instead we should do this:

Guys, here's a workaround until the tests are fixed:

Install the @sinonjs/fake-timers package

import { install } from '@sinonjs/fake-timers';
install({ now: new Date('2024-12-01') });

import React, { useEffect, useState } from "react";

function EmployeeValidationForm() { const [form, setForm] = useState({ name: "", email: "", employeeId: "", joiningDate: "" }) const [errors, setErrors] = useState({ isNameError: true, isEmailError: true, isEmployeeIdError: true, isDateError: true }); const [isButtonDisabled, setIsButtonDisabled] = useState(false); const [touched, setTouched] = useState({ name: false, email: false, employeeId: false, joiningDate: false });

useEffect(() => { if (Object.values(form).some(val => val === "" || val === null || val === undefined)) { setIsButtonDisabled(true) } else if (Object.values(errors).some(error => error === true)) { setIsButtonDisabled(true) } else { setIsButtonDisabled(false) } }, [form, errors])

const handleOnChange = (e) => { setForm({ ...form, [e.target.name]: e.target.value })

if (e.target.name === "name") {
  if (!/^[A-Za-z\s]+$/.test(e.target.value)) {
    setErrors({ ...errors, isNameError: true })
  } else {
    setErrors({ ...errors, isNameError: false })
  }
}

if (e.target.name === "email") {
  if (!/^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(e.target.value)) {
    setErrors({ ...errors, isEmailError: true })
  } else {
    setErrors({ ...errors, isEmailError: false })
  }
}

if (e.target.name === "employeeId") {
  if (e.target.value.length !== 6) {
    setErrors({ ...errors, isEmployeeIdError: true })
  } else {
    setErrors({ ...errors, isEmployeeIdError: false })
  }
}

if (e.target.name === "joiningDate") {
  if (new Date(e.target.value) > new Date()) {
    setErrors({ ...errors, isDateError: true })
  } else {
    setErrors({ ...errors, isDateError: false })
  }
}

}

const handleOnSubmit = () => { setForm({ name: "", email: "", employeeId: "", joiningDate: "" }) setErrors({ isNameError: true, isEmailError: true, isEmployeeIdError: true, isDateError: true }) }

const handleBlur = (e) => { setTouched({ ...touched, [e.target.name]: true }); };

return ( {errors.isNameError && Name must be at least 4 characters long and only contain letters and spaces

export default EmployeeValidationForm;

In the test, the join date “2025-04-12” is used as a future date, but we’ve already passed that day 😄. It would be better to use a dynamic value instead of a hardcoded one.
