As a developer I want to create, register and authenticate/refresh MeLi Test accounts to test different parts of the app.

[tmilar]

Currently a test user account can be created using Mercadolibre API, but this retrieves only a {nickname, password} pair, and has some problems:

• The same test account can't be retrieved ever again
• Creation limited to 10 accounts per Client Owner (that is, per Application / MERCADOLIBRE_CLIENT_ID)
  • Accounts are only deleted automatically after 60 days of inactivity
• The Account access token can only be refreshed using client owner Application secret id.

Provide a tool/script to manage Mercadolibre Test accounts easily.
