javascript - Chai expect objects inside array to not include multiple properties

Question

How to assert that all objects inside array do not include multiple properties. Example all of them should not include keys "email" and "phone".

const myArray = [
   {name: "John Doe", email: "[email protected]", phone: "9xxxxxxxxxx"},
   {name: "Jane Doe", email: "[email protected]", phone: "9xxxxxxxxxx"},
   {name: "Johny Doe"}
]

// this seems to do what I want 
// but doesn't "something" check if any object passes the test?
expect(myArray).to.contain.something.that.does.not.include.any.keys("email", "phone")

Using chai-things.

You can filter your array for elements having both keys set:

myArray.filter(a => a.email && a.phone)

and expect the count is 0:

expect(myArray.filter(a => a.email && a.phone)).to.be.an('array').that.is.empty;
