How to set multiple environment variables in a single line on Windows?

I'm working on a Node.js project and using Jest as the test framework. This project runs on Windows as it happens, and I'm having a heck of a time setting more than one environment variable on the command line.

Here's the relevant line in package.json

  "scripts": {
     "test": "SET NODE_ENV=test & SET DB_URI=postgresql://<database stuff>> & jest -t Suite1 --watch --verbose false"
  },

As can be seen above, I'm setting both a NODE_ENV and DB_URI environment variable prior to running jest via npm run test.

My problem is the that DB_URI environment variable doesn't appear to be set when jest runs. The error I get back from jest makes it obvious it can't find it. I do know that the first, NODE_ENV environment variable is set ok, but am not sure what's wrong with the second one, did I get the syntax wrong somehow? Is anyone with jest experience on Windows doing something similar to what I'm trying?

If you are setting the environment variables from powershell you can do like so:

cmd /K "set f=df & echo %f%"

The output will be "df"

I'd suggest you to add cross-env. It should be able to set multiple environment variables for Windows and POSIX

package.json 
{
  // ...
  "scripts": {
    "test": "cross-env NODE_ENV=test DB_URI=postgresql://<database stuff>> jest -t Suite1 --watch --verbose false"
  },
  "devDependencies": {
    "cross-env": "^6.0.0"
  }
}

Just make the following change:

Use &&, also you need to remove the white space before and after the "&&".

"scripts": {
     "test": "SET NODE_ENV=test&&SET DB_URI=postgresql://<database stuff>>&&jest -t Suite1 --watch --verbose false"
  },
