/**
* Test the Joomla\Log\Log::setInstance method to make sure that if we set a logger instance Joomla\Log\Log is actually going
* to use it. We accomplish this by setting an instance of LogInspector and then performing some
* operations using Joomla\Log\Log::addLogger() to alter the state of the internal instance. We then check that the
* LogInspector instance we created (and set) has the same values we would expect for lookup and configuration
* so we can assert that the operations we performed using Joomla\Log\Log::addLogger() were actually performed on our
* instance of LogInspector that was set.
