Test

测试 stook 是一件非常简单的事，因为测试 stook 也就是在测试 react hooks。

推荐使用 react-hooks-testing-library工具来测试 stook。

安装依赖

npm install -D @testing-library/react-hooks react-test-renderer

例子

useCounter.ts

function useCounter() {

const [count, setCount] = useStore('Counter', 0)

const decrease = () => setCount(count - 1)

const increase = () => setCount(count + 1)

return { count, increase, decrease }

}

useCounter.test.ts

import { renderHook, act } from '@testing-library/react-hooks'

import useCounter from './useCounter'

test('should increment counter', () => {

const { result } = renderHook(() => useCounter())

act(() => {

result.current.increase()

})

expect(result.current.count).toBe(1)

})
