class Civi not found

Question

I'm trying to use the Civi class to debug an extension with build kit, but after I add this line:

   `Civi::log()->info('Hello, log!');` 

to my class I get:

ampuser@58e3a823b9ee:/opt/buildkit/build/dmaster/sites/default/files/civicrm/ext/api4$ phpunit4 PHP Fatal error: Class 'Civi\API\V4\Civi' not found in /opt/buildkit/build/dmaster/sites/default/files/civicrm/ext/api4/Civi/API/V4/Action.php on line 117

I feel like this ought to work out of the box... am I doing something wrong?

This feels like a variant of this and this question ... but different in that I'm looking for the pattern to call a core class

Answer 1

Ok, so it turns out I was kinda doing something wrong...

What I needed was a simple \ prefix:

\Civi::log()->info('Hello, log!');
