Test::SubCalls - Track the number of times subs are called



NAME

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 cacheing 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 the Test::More manpage (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.
