I am trying to test my node.js code using Mocha, Sinon, and chai. 

var callback = function (err, resultSet) {
    should.exist(resultSet);
    stubbedExecuteSqlQuery.should.be.called;
    done();
};
stubbedExecuteSqlQuery.yields(null, expectedResultSet);
db.getResults(param1,param2, user, callback);

when the above code gets executed, it throws an error : 

Invalid Chai property: called. Did you mean "all"?

The code used to work fine on chai version ^3.5.0 but after my recent package upgrade to ^4.1.2 the code has stopped working and has started throwing such errors.

I tried searching for it on the internet but could not find any useful information.

Any help will be appreciated. Thanks in advance!

    According to Chai's current documentation, the syntax should be the following : `spy.should.have.been.called()`. Also you should take a look at the breaking changes of the different versions that you've skipped : http://www.chaijs.com/releases/ – boehm_s Jun 25 '18 at 13:51

    Does this answer your question? [Invalid Chai property when calling calledOnce](https://stackoverflow.com/questions/45314317/invalid-chai-property-when-calling-calledonce) – Sanderfish Jun 24 '21 at 19:07

I had a similar issue, I think it had something to do with using .yields I ended up using .calledOnce . Try the following:

assert(stubbedExecuteSqlQuery.calledOnce);

The upside with this is that if needed you can do .calledTwice etc..
