mocha-mongo Build Status

Set of mongodb testing helpers for mocha

mocha's TDD testing style used here and only the test function is used

Initialization

var mongo = require('mongo-mocha')('mongodb://localhost');

Using the db in tests

var ready = mongo.ready(); //only need to create this once

test('using the db', ready(function(db, done) {

    db.collection('test').insert({hello: 'world'}, done);
}));

Use fresh collections without data

We need to ensure collections are cleaned before running the test.

var clean = mongo.cleanCollections(['coll1', 'coll2']); //only need to create this once

test('test using cleaned collections', clean(function(db, done) {

    db.collection('coll1').find().count(function(err, count) {

        assert.equal(count, 0);
        done();
    });
}));

Drop the whole db

var drop = mongo.drop(); //only need to create this once

test('test using a fresh db', drop(function(db, done) {

    db.collection('coll1').find().count(function(err, count) {

        assert.equal(count, 0);
        done();
    });
}));
