I got these scripts

{
    "test": "mocha --require babel-core/register src/**/*.test.js",
    "test:watch": "yarn test --watch"
}

and they work perfect on mocha 5.0.5, but i just created a new project and installed mocha 5.1.0 and the npm run test:watch command doesn't work. I mean it doesnt give any error, it executes the tests and finish the process, if i have to run the tests again i have to run the command again and again.

Workaround: Going back to 5.0.5 for now.
