NAME
Test::Spy::Observer - method observer
SYNOPSIS
$spy->set_base($base_object);
my $method = $spy->add_observer('method_name');
ok !$method->was_called;DESCRIPTION
This class objects let you examine call data of a specific method without actually replacing its behavior.
Observer is similar to Test::Spy::Method, but it does not actually mock what the method is doing, only attaches itself to what already exists. For this reason, it makes sense to use it together with "base" in Test::Spy.
Call history methods
These methods are the same as documented in "Call history methods" in Test::Spy, but when called on this class objects, you don't need to setup "context" in Test::Spy.
