1. If user enters in the input field 'company' or 'test' i want Yup to mark this as failed validation.

2. If user enter companyThis or *test* (* === wild card), also want that to fail.

Can't seem to find that Yup has a method for this thing, so probably something custom?

Currently in Yup schema i have.

    const schema = yup.object().shape({
      username: yup
        .string()
        .min(4, 'User name to short')
        .matches(/^[A-Za-z0-9]+$/, 'Only numbers and letters are allowed')
        .required('Required'),
    });
