Export node variable in windows like on mac

Question

I would like to pass variables to a mocha test, which is not as simple as expected. Passing a variable like this:

npm run test --scope=28

is not possible, because mocha will catch the input. I also tried to use the npm minimist package and using a user prompt failed also.

Anyway my colleagues are using a mac and are able to pass an env variable by using this command

export testscope="18" && npm run test

But unfortunately this will not work in Windows. So my question is, is there a similar export command for Windows?

Answer 1

You can use the CMD.EXE set command for this, acts like export on *NIX.

set testscope=18 && npm run test

You did not say which shell you are using, in PowerShell, you might want to do this:

$env:testscope= 18; npm run test

The OP finally decided on installing the Linux subsystem of Windows, to do this, you issue the following in Powershell ("opened as Administrator"):

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
