What is 'testRoom' in Licode ? When and where is it created?

1

There are a lot of references to testRoom when creating a token, however I could not find anything about it in database or elsewhere.

For example:

if (currentService.testRoom !== undefined) {
    tr = currentService.testRoom._id;
}

code snippet above checks for a testRoom in a service object and uses it’s id. Can anyone enlighten me on this ?
