NAME

    Test::Exec - Test that some code calls exec without terminating testing

VERSION

    version 0.02_01

SYNOPSIS

     use Test::More;
     use Test::Exec;
     
     is_deeply exec_arrayref { exec 'foo', 'bar', 'baz' }, [qw( foo bar baz )], 'found exec!';
     is exec_arrayref { }, undef, 'did not exec!';

DESCRIPTION

    Test::Exec provides the most simple possible tools for testing code
    that might call exec, which would otherwise end your test by calling
    another program. This code should detect and capture exec calls, even
    if they are inside an eval.

    The concept was implementation was based on Test::Exit, but applied to
    exec instead of exit.

FUNCTIONS

 exec_arrayref

     exec_arrayref { ... }

    runs the given code. If the code calls exec, then this function will
    return an arrayref with its arguments. If the code never calls exec, it
    will return undef.

CAVEATS

    This module installs its own version of exec in CORE::GLOBAL::exec, and
    may interact badly with any other code that is also trying to do such
    things.

SEE ALSO

    Test::Exit

      Very similar to (and inspired) this module, but for exit testing
      instead of exec.

    Test::Mock::Cmd

      Provides an interface to mocking system, qx and exec.
