How to check the value is in object with Chai?

Question

Is it possible to test the value is contained within certain array with Chai assertion library?

Example:

var myObject = {
    a : 1,
    b : 2,
    c : 3
};
var myValue = 2;

I need to do something like this (however it is not working):

expect(myObject).values.to.contain(myValue);
//Error: Cannot read property 'to' of undefined

expect(myObject).to.contain(myValue);
//Error: Object #<Object> has no method 'indexOf'

How can I test this?

Answer 1

Alternatively if you want to check the value along with the property you can do

expect(myObject).to.have.property('b', myValue);

You won't need the plugin for this check.
