babel-register not working in mocha test, nodejs react

Question

Hi I am struggling for a week solving this Unexpected token 'import' error.

After tons of searching, now I know that this is a problem of babel-register which is not applying to mocha test, while webpack serve works fine.

At first I had an Unexpected token 'import' error when using antd library and I followed other solutions which told me to set .babelrc(setting node_modules: false)

But now I am getting same Unexpected token 'import' error from my test file. Please help me... This is not a duplicate and I've done almost every solution in the web related to this. I'm pretty sure that --require babel-register is not working in mocha test. Thank you.
