Testing collection security.

[ghost]

Hello everybody.

I'm trying to have tested my collection security, for that I have the following:

if (!(typeof MochaWeb === 'undefined')) {
MochaWeb.testOnly(function () {

            before(function(done) {
                    Meteor.logout(function(error) {
                        if(error) {
                            testLog.error('problem trying to logout', error.toString());
                        }
                        done();
                    });
            });

           describe("guest user cannot perform collection operations", function() {

                it("guest users cannot insert any data", function() {

                    // this is an object that complains with Parts SimpleSchema
                    var newPart = wolfSettings.dataset.partNotInserted;

                    try {
                        var result = Parts.insert(newPart);
                        chai.expect(result).is.not.ok;

                    } catch(e) {
                        chai.assert.isTrue(false, "exception was thrown " + e.message);
                    }

                });

          });

});
}

The problem is the tests is always failing, Part seems to be inserted into the database.
"exception was thrown expected 'yGu4Nu3G6N9MisAkC' to be falsy: expected false to be true"

Is the meteor mirror copying the collections without the allow security defined on the main collection?

Many thanks,
