如何在 jest 的覆盖范围内忽略由 jest 生成的快照？

Question

我正在为 jest 设置一些新配置，我忽略了一些文件，例如 *.stories.js，但是当我使用 *.js.snap 或 *.snap 时，jest 无法正常工作.

我正在使用 react-scripts，同样使用 jest

例如，如果我只忽略 *.stories.js，如下命令所示：

react-scripts test --coverage --collectCoverageFrom=!src/**/*.stories.js

但是如果我添加 *.js.snap 找不到其他文件 snap

react-scripts test --coverage --collectCoverageFrom=!src/**/*.stories.js --collectCoverageFrom=!src/**/*.js.snap

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

我解决了确实在里面添加了配置package.json

  "jest": {
    "collectCoverageFrom": [
      "!<rootDir>/src/**/*.stories.js",
      "src/**/*.{js,jsx}",
      "!<rootDir>/node_modules/"
    ]
  },

如何在 jest 的覆盖范围内忽略由 jest 生成的快照？

How ignore snapshot generated by jest on jest's coverage?

javascript

testing

unit-testing

reactjs

jestjs
