All babel modules/plugins are on the latest version of babel v6. Mocha is on v4.0.1.
Setup:
// .babelrc
{
presets: [
"stage-3",
[
"env",
{
"targets": {
"browsers": [
"last 2 versions"
],
"node": "current"
}
}
]
"react"
],
plugins: ["transform-runtime", "syntax-dynamic-import"]
}
// mocha.opts
--recursive
--reporter progress
--require babel-polyfill
--require babel-register
--timeout 20000
So when I run my test suite I still get: error stack trace.
I would have to imagine it has something to do with babel-register and syntax-dynamic-import not working together correctly. Because when I use it with babel-loader in webpack I don't get any syntax errors on transpile.
This answer on babeljs slack from Satyajit Sahoo cleared things up for me:
syntax-dynamic-importwill only enable the syntax in babylon, which means it babylon can parse the code without syntax error. the codeimport(...)is still there, which node doesn’t understand and you still need to transpile it.dynamic-import-nodetranspiles theimport(...)torequirewhich node understands. On client, the transpilation step is not necessary since Webpack understands the syntax and does the bundling.
