npm install --save-dev riot-testing-library

import render, {fireEvent} from 'riot-testing-library'
import TestTag from './test.tag'

test('should show count text  when rendered', () => {
  const {queryByTestId} = render(TestTag, {count: 10})
  expect(queryByTestId('count').textContent).toBe('10')
})

test('should add count when click add button text', () => {
  const {queryByTestId} = render(TestTag, {count: 1})
  expect(queryByTestId('count').textContent).toBe('1')
  fireEvent.click(queryByTestId('button'))
