I am using jest with react-testing-library for the most part without issues until I started to move to the screen > getByText/etc way of testing.
Test
describe('test the dashboard when loaded', () => {
it('is not loading', async () => {
render(<ComponentToTest />)
expect(screen.getByText(/loading/i)).not.toBeInTheDocument()
})
it('displays the case summary correctly', async () => {
const allCasesElement = getByTestId(/Timeline/i)
within(allCasesElement).findByText('30/12/2021')
within(allCasesElement).findByText('12:06')
within(allCasesElement).findByText('enums.case.VERIFICATION_GO_TO_COMPLETION')
})
})
Failure
TS2339: Property 'getByText' does not exist on type 'Screen'.
screen.getByText is not a function
