描述问题

在使用create-react-app设置时，Storybook在使用addon-coverage时不生成覆盖率报告。

----------|---------|----------|---------|---------|-------------------
File      | % Stmts | % Branch | % Funcs | % Lines | Uncovered Line #s 
----------|---------|----------|---------|---------|-------------------
All files |       0 |        0 |       0 |       0 |                   
----------|---------|----------|---------|---------|-------------------

复现链接

由于在StackBlitz上Playwright失败，无法复现。

复现步骤

设置：在本地(sandbox/cra/default-ts/after-storybook)进行设置
安装“@storybook/test-runner”和“@storybook/addon-coverage”
在package.json的scripts部分中添加"test-storybook": "test-storybook -- --coverage"
在.storybook/main.ts的addons部分中添加“@storybook/addon-coverage”
为现有组件添加一个测试。
(重新)启动Storybook
运行npm run test-storybook

我希望能够得到一些覆盖率，但是一切都卡在0%上。

npm run test-storybook

> before-storybook@0.1.0 test-storybook
> test-storybook -- --coverage

免责声明：由于信息是自动生成的，可能存在不准确的情况。
要解决@storybook/addon-coverage与CRA设置不兼容的问题，请按照以下步骤操作：

更新.storybook/main.ts:

import type { StorybookConfig } from '@storybook/react-webpack5';

const config: StorybookConfig = {
  stories: [],
  addons: [
    '@storybook/addon-coverage',
  ],
};

export default config;

使用覆盖率运行测试运行器:

npm run test-storybook -- --coverage

生成LCOV报告:

npx nyc report --reporter=lcov -t coverage/storybook --report-dir coverage/storybook
