我创建了样例react项目并添加了JEST和酶依赖性来测试我的组件。但是在运行测试套件时出现以下错误: 错误: 无法从“ App.js”中找到模块“组件/添加”
However, Jest was able to find:
'components/Add.js'
You might want to include a file extension in your import, or update your 'moduleFileExtensions', which is currently ['web.js', 'js', 'web.ts', 'ts', 'web.tsx', 'tsx', 'json', 'web.jsx', 'jsx', 'node'].
See https://jestjs.io/docs/en/configuration#modulefileextensions-array-string

您是否尝试过使用相对导入?
select product.id, name, hand, count(qty)
from product
left join stock on pid=product.id
让我知道是否有帮助:)

导入的编写方式,您可能在路径中使用别名。如果您使用的是webpack,请检查webpack.config.json中的resolve.alias
字段以确认这一点。
如果确实设置了别名,则还必须将它们添加到jest配置中。这是使用moduleNameMapper
完成的。例如,
{
"moduleNameMapper": {
"components/(.*)$": "<rootDir>/PATH_TO_COMPONENTS/$1",
}
}
