react+jest测试问题

Question

一直在报格式错误我也不知道为啥，我只是单纯想测试一下好难受

这是.babelrc文件内容
{

"@babel/preset-env",
"@babel/preset-react"

],
"plugins": [

[
  "@babel/plugin-proposal-decorators",
  {
    "legacy": true
  }
],
"@babel/plugin-transform-react-constant-elements",
"@babel/plugin-transform-react-inline-elements",
"@babel/plugin-syntax-dynamic-import",
"@babel/plugin-syntax-import-meta",
"@babel/plugin-proposal-class-properties",
"@babel/plugin-proposal-json-strings",
"@babel/plugin-proposal-function-sent",
"@babel/plugin-proposal-export-namespace-from",
"@babel/plugin-proposal-numeric-separator",
"@babel/plugin-proposal-throw-expressions",
"@babel/plugin-proposal-export-default-from",
"@babel/plugin-proposal-logical-assignment-operators",
"@babel/plugin-proposal-optional-chaining",
[
  "@babel/plugin-proposal-pipeline-operator",
  {
    "proposal": "minimal"
  }
],
"@babel/plugin-proposal-nullish-coalescing-operator",
"@babel/plugin-proposal-do-expressions",
"@babel/plugin-proposal-function-bind"

]
}

如果单从题目来看的话，单独的jest是不能测试react组件的
源码，版本，报错的完全截图，甚至一个可复现的demo 请放出来，这样您的问题，会被更多的人所回答。
