Cannot get lesson 2 tests to initiate.

[Connor-Flewitt]

I have installed yarn using yarn install and checked it was successful using yarn version. I then use yarn dev within the CLI of visual studio, to build the project and start the server.
I then try to run yarn test-routes to check my code against the test criteria (at this stage I haven't written any code, but I have the lesson 2 directory open in VS code, I just want to check the test is working), but receive the following error:

'Connors-MBP:api-design-node-v3-lesson-2 connorflewitt$ yarn test-routes

$ npm run test -t router

Is anyone able to recreate and/or solve this issue?

Exactly the same is happening to me.

Try removing cross-env from the test script inside your package.json file

Branch: lesson-2 or lesson-2-solution

changes to be made in filename: package.json

Before:

"scripts": {
"build": "babel src --out-dir dist",
"test": "cross-env NODE_ENV=testing jest --forceExit --detectOpenHandles --silent",
"test-routes": "npm run test -t router",
"test-models": "npm run test -t model",
"test-controllers": "npm run test -t controllers",
"test-auth": "npm run test -t Authentication:",
"dev": "nodemon --exec npm run restart",
"restart": "rimraf dist && npm run build && npm run start",
"start": "node dist/index.js"
}

After:

"scripts": {
"build": "babel src --out-dir dist",
"test": "NODE_ENV=testing jest --forceExit --detectOpenHandles --silent",
"test-routes": "npm run test -t router",
"test-models": "npm run test -t model",
"test-controllers": "npm run test -t controllers",
"test-auth": "npm run test -t Authentication:",
"dev": "nodemon --exec npm run restart",
"restart": "rimraf dist && npm run build && npm run start",
"start": "node dist/index.js"
}

Please let me know if this doesn't work out!

Updating Jest to the latest version fixed the issue for me.

$npm remove jest
$ npm install jest --save
