@c9qsm62x It was added for coverage IIRC as those code paths still exist in the useInput hook.

I think the test has stopped doing what it was meant to since user-event was updated to v14 – fireEvent.keyDown(input, { key: 'Enter' }) probably makes more sense.

Test DatePicker › when a single date picker is rendered and the picker is opened › when Shift-Tab is pressed once › traps the focus within the picker

it looks like this behaviour has changed in V8
https://react-day-picker.js.org/basics/keyboard#example Having a look at this example it looks like when a date is in focus and you press shift+tab it will focus on the next month button.

Yep that test looks wrong now as the initial focus is now set to the selected date.

Should be something like this I think:

    describe('when Tab is pressed once', () => {
      beforeEach(async () => {
        await user.tab()
      })

      it('traps the focus within the picker', () => {
        expect(
          wrapper.getByLabelText(PREVIOUS_MONTH_BUTTON_LABEL)
        ).toHaveFocus()
      })

      describe('and Shift-Tab is then pressed once', () => {
        beforeEach(() => {
          return user.tab({ shift: true })
        })

        it('still traps the focus within the picker', () => {
          expect(
            wrapper.getByRole('button', { name: '5th December (Thursday)' })
          ).toHaveFocus()
        })
      })
    })

Closing for now because it's very stale - hoping to come back to this soon.
