I am following module 2.2.3 on the Foundation Certificate course and get to this bit where it says to run the test using the code “node\_modules/jest/bin/jest.js src/ **tests** /exampleComponent.test.js”

When i open the terminal and add that code in, then all it does is open up the exampleComponent.test.js file and place the cursor at the start of that file. I cannot see any test run information anywhere.

What am I doing wrong?

Here is a screenshot of my VS Code with terminal once I have added that code:

That is odd behaviour. Not sure what is going on there exactly.

One suggestion would be to try installing jest globally with `npm install -g jest` and then attempt to run:

```auto
jest src/ __tests__ /exampleComponent.test.js

```

Try typing it in as well so that no hidden characters are appearing.

Thanks Mark. It turned out to be connected with my execution policy. After a bit of reading about that, I found that I had an undefined signature, which meant that it wouldnt let me run any scripts. I then corrected the signature for my currentuser and it has now let me run the test using your suggested code above.
