TypeError: Cannot read property 'getAllByTestId' of undefined

expect(
    wrapper.getAllByTestId('data-testid')
)

where

wrapper = render(
    <Router>
        <SomeFormComponent>
    </Router>
)

render imported from @testing-library/react and Router is MemoryRouter imported from react-router-dom

Looks like it's do to with number inputs specifically :)

I am attempting to reproduce this:

  describe('Repro', () => {
    it('should render', () => {
      wrapper = render(
        <Router>
          <NumberInput
            data-testid="blah"
            name="number-input"
            onChange={onChangeSpy}
          />
        </Router>
      )

      expect(wrapper.getAllByTestId('blah')).toHaveLength(1)
    })
  })

The test passes. Are you able to provide a failing test?

This is because NumberInput is dependent on the canvas API. We have worked around this by adding import 'jest-canvas-mock' to setupTests.ts.
