How to test meta.valid react final form

Question

I am using react-final-form to validate the input field as below:

buildInputComponent() {
return (
  <InputField
    id="input-field"
    label="description"
    isInvalid={meta.touched && !meta.valid}
    error={meta.error}
    value=input.value
    required
    onChange={(event) => {
      input.onChange(event.target.value);
    }}
  />);
}

i have tested it as follows:

it('sets the frequency state to the value in the frequency select', () 
=>   {
       const inputValue = '30';
       testInput.find('input-field').find('input').hostNodes()
          .simulate('change', { target: { value: inputValue } });
     testInput.update();

   expect(testInput.find('ReactFinalForm').instance().state.schedule.frequency).toEqual(frequency);

  });'

This covers the test for meta.touched, but the coverage report shows it does not cover the test for !meta.valid I have no idea how to cover the test for !meta.valid I tried having empty field as below:

testInput.find('input-field').find('input').hostNodes()
      .simulate('change', { target: { value: frequency } });

But this did not cover it, Please help

I suspect that your touched is always false because you are not focusing and blurring the field, ergo the latter half of the && is never evaluated.
