NAME ^

Test::Carp - test your code for calls to Carp functions

VERSION ^

This document describes Test::Carp version 0.2

SYNOPSIS ^

    use Test::More tests => 42;
    use Test::Carp;
    
    ok($x eq $y, "X does equal Y");
    does_carp(\&function);
    does_croak(\&function, 1, 2, 3);
    does_carp_that_matches(\&function, qr/whoopsy/);
    does_croak_that_matches(\&function, 1, 2, 3, qr/a likely story/);

DESCRIPTION ^

Call given code (with given arguments) and tests whether the given Carp function (or their imported versions) are called (with a given value) or not.

INTERFACE ^

All functions are put in the caller's name space during import(). If you'd rather use their full name space and not clutter up the current package with functions just:

  require Test::Carp;

or

  use Test::Carp ();

instead of

  use Test::Carp;

being ok() w/ ok()

Internally, Test::Carp uses Test::More::ok() (require()ing in Test::More if needed) when it needs to use an ok() function.

If you want to specify a different one for it to use simply supply a coderef in the use statement.

   use Test::Carp \&Test::Foo::ok;

The function should take the same args as Test::More::ok() and probably behave the same as well.

carp()/cluck() functions

does_carp()

Test whether the given code ref, when executed, calls carp().

Test fails if carp() is not called. There are 2 forms:

Without arguments to codreref:

   does_carp(sub {...});

With arge to coderef:

   does_carp(sub {...},"first arg to coderef", "second arg to coderef", ...);
does_carp_that_matches()

Test whether the given code ref, when executed, calls carp() with a specific message.

The test fails if carp() is not called with the given message.

The last argument should be a string or Regexp ref (i.e. qr//) to match the message against.

There are 2 forms:

Without arguments passed to codreref:

   does_carp(sub {...}, $match_me)

With arguments passed to coderef:

   does_carp(sub {...},"first arg to coderef", "second arg to coderef", ..., $match_me);
does_cluck

Like does_carp() but for cluck()

does_cluck_that_matches

Like does_carp_that_matches() but for cluck()

croak()/confess() functions

These functions stop running at the point it calls the [croak|cluck]() just like in normal code.

does_croak()

Like does_carp() but for croak()

does_croak_that_matches()

Like does_carp_that_matches() but for croak()

does_confess()

Like does_carp() but for confess()

does_confess_that_matches()

Like does_carp_that_matches() but for confess()

DIAGNOSTICS ^

Throws no warnings or errors of it's own.

CONFIGURATION AND ENVIRONMENT ^

Test::Carp requires no configuration files or environment variables.

DEPENDENCIES ^

Test::More for ok() unless you define a different ok() for it to use.

It uses Carp in order to ensure carp and corak are defined before it does what it does.

INCOMPATIBILITIES ^

None reported.

BUGS AND LIMITATIONS ^

No bugs have been reported.

Please report any bugs or feature requests to bug-test-carp@rt.cpan.org, or through the web interface at http://rt.cpan.org.

TODO ^

Corresponding does_not_* functions. (v0.2)

TODOs in 02.functions.t (v0.2)

Maybe count and overall call info type functions, depending on demand ?

Determine [what needs done/if it should be done/etc] to make the test syntax not require a codref ?

Add mostly-internal Carp functions like (short|long)mess[_heavy](), etc ?
