# Test::Carp(3pm)

test your code for calls to Carp functions

## 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 ?
