不过，今天我将向你展示新出土的宝藏 —— **React 最为深藏不露的秘密**：

感谢 [Dan Abramov](https://medium.com/@dan_abramov)！

这就是函数式 setState 的强大之处 —— 在组件类**外部**声明 state 的更新逻辑，然后在组件类**内部**调用之。

    // 在组件类之外
    function increaseScore (state, props) {

  "onTestResult": Object {
    "called": true,
    "times": 1,
  },
  "onTestStart": Object {
    "called": true,
    "path": false,
  },
  "options": Object {
    "christoph": "pojer",
    "dmitrii": "abramov",
    "hello": "world",
  },
}
`;

exports[`Custom Reporters Integration TestReporter with all tests passing 1`] = `
Object {
  "onRunComplete": Object {
    "called": true,
    "numFailedTests": 0,

`components` and stateful parent components called `containers`.

### Could not find "store" in either the context or props

If you have context issues,

1. [Make sure you don’t have a duplicate instance of React](https://medium.com/@dan_abramov/two-weird-tricks-that-fix-react-7cf9bbdef375) on the page.
2. Make sure you didn’t forget to wrap your root or some other ancestor component in [`<Provider>`](#provider-store).
