Make sure Jest's configuration does not exclude this directory.
To set up Jest, make sure a package.json file exists.

jest.config.js根目录下面没有components目录

module.exports = {
  verbose: true,
-   roots: ['<rootDir>/components'],
+  roots: ['<rootDir>/components', '<rootDir>/src'],
  moduleNameMapper: {
    '\\.(css|less|scss)$': 'identity-obj-proxy',
    '^components$': '<rootDir>/components/index.tsx',
    '^components(.*)$': '<rootDir>/components/$1',
  },
  testRegex: '(/test/.*|\\.(test|spec))\\.(ts|tsx|js)$',
  moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx'],
  testPathIgnorePatterns: ['/node_modules/', '/lib/', '/esm/', '/dist/'],
  preset: 'ts-jest',
  testEnvironment: 'jsdom',
};

之前把文档站点换成 dumi，源文件的文件夹名称也改了，这里漏掉了，感谢指出，我抽空改一下
