I would rather test this with something like 
````
users.each(function (user) {
    if (user.secretValue == '42') {
        expect(user.username).toEqual("Bill");
    } else {
        expect(user.username).toEqual("Bob");
    }
});

I know those assertion do exactly the same as yours, but here it as totally clear that if secretValue was 42 it should have been updated, and if not it should remain Bob
