Tests not runnable on running `npm run test` ( NODE_ENV not recognized)

Actual Behavior

The test and test:watch scripts in package.json use NODE_ENV=test jest directly. This syntax works on macOS/Linux shells but fails on Windows (CMD, PowerShell, Git Bash). As a result, tests cannot be executed on Windows machines.

• On Windows, running:

  npm run test
  

  produces:

  'NODE_ENV' is not recognized as an internal or external command,
  operable program or batch file.
  

• This makes tests not runnable on Windows environments.

Expected Behavior

• Running:

  npm run test
  

  should start Jest with NODE_ENV=test set correctly.
• Tests should run successfully across all operating systems.

Steps to reproduce

Steps:

1.Clone the repo on a Windows machine.
2. Run npm install
3.Run npm run test

Snippet:

// Paste your code here :)

Start in package.json by reviewing the test and test:watch scripts and their NODE_ENV assignment. Run npm run test on a Windows shell and a Unix-like shell to compare behavior. Done means both commands launch Jest successfully with NODE_ENV=test.
