Jest 24.1和babel 7.3.3在大多数测试中仍然存在问题

Question

好了，这几天我一直在为这件事发疯。因此，我最后将向StackOverflow的优秀人员寻求非常需要的帮助:)

Here is the error I'm getting => Identifier 'global' has already been declared

And it seems to not recognize the require keyword

所以目前，50%的测试套件通过了测试。

它似乎只在调用redux reducers的测试中抛出。因为对于几乎所有失败的测试，错误都是相同的。

这是我当前的babel.config.js

module.exports = function(api) {
    const isTest = api.env('test')

    const presets = [
        isTest && [
            '@babel/preset-env',
            {
                targets: {
                    node: 'current',
                },
            },
        ],
        [
            'next/babel',
            {
                'preset-env': {},
                'transform-runtime': {},
                'styled-jsx': {},
                'class-properties': {},
            },
        ],
    ].filter(Boolean)

    const plugins = ['babel-plugin-styled-components']

    return {
        presets,
        plugins,
        sourceType: 'unambiguous',
    }
}

并且依赖项在

    "devDependencies": {
        "@babel/core": "^7.3.3",
        "@babel/preset-env": "^7.3.1",
        "@cypress/snapshot": "^2.0.1",

Answer 1

好了，我现在已经解决了，这不是jest或巴别塔的问题。我有我想要的，一个保留的名称作为一个变量，它会抛出一个令人困惑的错误，因为自上一次巴别塔以来。
