bctest

A simple, small javascript framework to execute timed tests from within a mongoDB shell.

Basic use:

> use mydb;  // important to set your db ref
> load("bctest.js");
true
> BCTest.performTests([ { f: function() { db.getCollectionNames(); } } ])

In general, you'll want to set up your set of tests in a separate file and call BCTest.performTest() at the end of the script.
load() the file to run the tests, tweak, save, reload, etc.

$ cat bct1.js
tests = [
     {
       collection: "researchfacetsflat",
       f: function() {
             r = db.researchfacetsflat.aggregate([ {$group: {_id: ''} } ]);
             return r;
       }
     }
     ,{
       collection: "researchfacetsflat",
       f: function() {
             r = db.researchfacetsflat.aggregate([ {$group: {_id: {} } } ]);
             return r;
       }
     }
];
BCTest.performTests(tests);

A few simple per-item options:

{
     collection: ”name",  // if present, will be used to emit counts and indexes
     mute:true, // if true, skip this test
     solo:true, // If true, run only this test (and other soloed tests too)
     show:true, // if true, emit the returned variable from the test function
     //…
}
