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

version 0.07

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!';

done_testing;

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".

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".

never_exec_ok { ... }

Runs the given code. If the code calls "exec", then the test will fail (but exec will be intercepted and not performed).

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.

Very similar to (and inspired) this module, but for "exit" testing instead of "exec".
Provides an interface to mocking "system", "qx" and "exec".
