Information on how to test custom management commands can be found in the

Overriding commands
===================
Django registers the built-in commands and then searches for commands in
:setting:`INSTALLED_APPS` in reverse. During the search, if a command name
duplicates an already registered command, the newly discovered command
overrides the first.
In other words, to override a command, the new command must have the same name
and its app must be before the overridden command's app in
:setting:`INSTALLED_APPS`.
Management commands from third-party apps that have been unintentionally
overridden can be made available under a new name by creating a new command in
one of your project's apps (ordered before the third-party app in
:setting:`INSTALLED_APPS`) which imports the ``Command`` of the overridden
command.
