mongod-run

Runs mongod. Useful when testing APIs.

Motivation

When running tests for APIs that are backed by a database, we usually either have the DB up as a service somewhere or do this extra step of bringing it up before running the tests. I didn't want to do any of these, so I wrote mongod-run.

Example

Note: I focused mainly on getting it working with mocha, as this is what I've been testing with.

var mongod = require('mongod-run');
 
before(mongod.start);
after(mongod.stop);
afterEach(mongod.cleanup('mongodb://localhost:27017/example.test'));
 
describe('my app', function () {
  // ...
});

API

• start(callback): runs mongod and call the callback once it is up and running.
• stop(): kills the mongod process. This is automatically called if/when the test process exits.
• cleanup(url): performs a cleanup on the database specified by the given url.

Notes

The mongod process is being ran with the following command:

mongod -f . --dbpath=<temp_directory> --rest

The temporary directory is removed at the end – either via .stop() or process exit.

I have the feeling that customizing this command line might be something that people might want to do. If so, feel free to submit a pull request!
