The "check" option to the findOne operation allows the caller to specify a Javascript predicate function which is called with the object returned by the query; each time the operation is run, benchRun() asserts that the predicate function returns true.
However, this option does not work; whenever it is used, an error is always thrown with message "no createDirectClient in clientOnly". See the following shell session:
> benchRun({ops:[{op: "findOne", query: {}, ns: "test.foo", check: function(obj) { return true; }}], seconds: 5})
