Test namespace not defined for console command

I am having an issue running unit tests with Piwik. When attempting to run the tests via the console command, I receive an error message that,

There are no commands defined in the "tests" namespace.

Running ./console with no other arguments confirms that there is no test namespace.

How do I enable testing from the console?

Hi there,

please try again with Piwik from Git

if you still have a problem create a bug report at: Issues · matomo-org/piwik · GitHub and please put there your OS information

Thank you Matt. That fixed my problem.
