Sub::Name - (re)name a sub SYNOPSIS
use Sub::Name; subname $name, $subref; $subref = subname foo => sub { ... }; DESCRIPTION
This module has only one function, which is also exported by default: subname NAME, CODEREF Assigns a new name to referenced sub. If package specification is omitted in the name, then the current package is used. The return value is the sub. The name is only used for informative routines (caller, Carp, etc). You won't be able to actually invoke the sub by the given name. To allow that, you need to do glob-assignment yourself. Note that for anonymous closures (subs that reference lexicals declared outside the sub itself) you can name each instance of the closure differently, which can be very useful for debugging. AUTHOR

Test::SubCalls - Track the number of times subs are called SYNOPSIS
use Test::SubCalls; # Start tracking calls to a named sub sub_track( 'Foo::foo' ); # Run some test code ... # Test that some sub deep in the codebase was called # a specific number of times. sub_calls( 'Foo::foo', 5 ); sub_calls( 'Foo::foo', 5, 'Use a custom test message' ); # Reset the counts for one or all subs sub_reset( 'Foo::foo' ); sub_reset_all(); DESCRIPTION
There are a number of different situations (like testing caching code) where you want to want to do a number of tests, and then verify that some underlying subroutine deep within the code was called a specific number of times. This module provides a number of functions for doing testing in this way in association with your normal Test::More (or similar) test scripts. FUNCTIONS
In the nature of test modules, all functions are exported by default. sub_track $subname The "sub_track" function creates a new call tracker for a named function. The sub to track must be provided by name, references to the function itself are insufficient. Returns true if added, or dies on error. sub_calls $subname, $expected_calls [, $message ] The "sub_calls" function is the primary (and only) testing function provided by "Test::SubCalls". A single call will represent one test in your plan. It takes the subroutine name as originally provided to "sub_track", the expected number of times the subroutine should have been called, and an optional test message. If no message is provided, a default message will be provided for you. Test is ok if the number of times the sub has been called matches the expected number, or not ok if not. sub_reset $subname To prevent repeat users from having to take before and after counts when they start testing from after zero, the "sub_reset" function has been provided to reset a sub call counter to zero. Returns true or dies if the sub name is invalid or not currently tracked. sub_reset_all Provided mainly as a convenience, the "sub_reset_all" function will reset all the counters currently defined. Returns true. SUPPORT
