When testing applications, often you find yourself needing to provide functionality in your test environment that would usually be provided by external modules. Rather than munging the %INC by hand to mark these external modules as loaded, so they are not attempted to be loaded by perl, this module offers you a very simple way to mark modules as loaded and/or unloaded.

$bool=mark_as_loaded(PACKAGE); Marks the package as loaded to perl. "PACKAGE" can be a bareword or string. If the module is already loaded, "mark_as_loaded" will carp about this and tell you from where the "PACKAGE" has been loaded already. $bool=mark_as_unloaded(PACKAGE); Marks the package as unloaded to perl, which is the exact opposite of "mark_as_loaded". "PACKAGE" can be a bareword or string. If the module is already unloaded, "mark_as_unloaded" will carp about this and tell you the "PACKAGE" has been unloaded already. $loc=is_loaded(PACKAGE); "is_loaded" tells you if "PACKAGE" has been marked as loaded yet. "PACKAGE" can be a bareword or string. It returns falls if "PACKAGE" has not been loaded yet and the location from where it is said to be loaded on success.
