Context
There are 2 helpers to load a service:

• $example = service('example');
  
• $example = single_service('example');
  

Only the first will let you use the following when testing:
Services::injectMock('example', $example);

This is not clear in the documentation, I assumed mocking would work for all services:
Testing / Getting Started / Mocking Services

Feature Request:
The framework looks for all service mocks instigated, either for:

• a shared instance (e.g. service('example'))
  or
  
• a non-shared instance (e.g. single_service('example'))
  

My current (user-side) solution:
in app/Config/Services.php

PHP Code:

public static function example(bool $getShared = true)
{
    if ($getShared)
    {
        return static::getSharedInstance('example');
    }
    elseif (isset(static::$mocks['example']))
    {
        return static::$mocks['example'];
    }

    return new Example();
}
