Hey,

I’m working on rewriting all the tests of all the requests but after 2 hours of searching the Internet, I can’t find a way to rewrite this test:

`tests["Name not null"] = response.name !== null && response.name !== ""`

If anyone has an idea to help me, I’ll be grateful.

Laurre

Hey @laureline.gagnon,

Welcome and thank you for posting your question ⭐

If I understand what you’re trying to achieve, would this work:

```
pm.test("Name not null", () => {
    pm.expect(response.name).to.not.be.null
    pm.expect(response.name).to.not.be.empty
}) 

```

I don’t really know the full context behind the question so this is only based on the limited information I have, happy to edit the response if this doesn’t work for you.

Thanks !  
That’s exactly what I want to do.  
Is there a list of all possible functions/commands following an expect?  
Because I didn’t find its possibilities during my research.

You’ll find all of the chai expect functions in the link that I provided in the answer 🙂
